Deep Cleaning A/C Unit

Dirty AC Coils

Deep Cleaning Service With Spring A/C Maintenance

How long has it been since an HVAC professional last serviced your A/C unit?  If your answer is years, you’ve likely got years of dirt caked onto your cooling fins.

Unionville Heating provides an exclusive service for deep-cleansing of your outdoor A/C unit. Cleaning will prolong the life of your air conditioning system. Extend your air conditioner’s efficiency and years of service by having it professionally deep-cleaned.

How And Why To Clean Your Air Conditioning Unit

Failure occurs because the unit is not clean, and you can extend its life by deep-cleaning it. Take it apart and wash it. Do this, and you’ll be cool for a long time.

Service begins by removing the grill and inspecting the wiring control box. Next, eliminate the dust blanket and clean the air conditioning coils. A/C coils extract heat from the house. The problem with a dirty A/C unit is that debris insulates the coils with caked-on layers of dust, preventing efficient cooling. You could save yourself two or three years of system replacement by performing a deep-clean service on your air conditioning unit. Deep-cleaning will extend the life of your unit. As we move towards recessionary times, repairing will be more cost-effective compared to replacement of the A/C.

Garage Heater Installation

Step 16 : Prepare for startup.

How do you install a furnace in a Garage?

Heating from a garage furnace is an excellent solution for expanding your living or working area during the cold months of the year. Turn your garage into a heated workshop, family play area or game day hangout.

A licensed HVAC contractor performs this How-To guide.

The gas furnace we chose is 96% efficient. That means of all the gas you buy to heat the space, only 4% will be expelled with the exhaust.
The Installation Manager visits the job site before the install date to consult on location and measurements for furnace placement and electrical and gas connection locations. The unit must have a dedicated circuit for power. The gas line is a continuous one-piece connection from the gas source to the furnace.

Step 16 : Prepare for startup.
Total Time Needed: 1 day

Required Tools:

- Pipe Wrenches
- Plyers
- Tin Snips
- Drill with masonry bit
- Hole Saw
- Ladder
- Scaffolding
- Electrical Testers/Multimeter
- Battery Powered/Cordless Drill
- Tape Measure
- Hammer
- Screw Drivers
- Hex Head Nut Drivers
- Caulking Gun

- Air Filter
- Hose clips and screws
- Caulk

Steps to install a garage furnace:

Step 1 : Select the right furnace for your application.
The Goodman furnace has tubular heat exchangers with high-efficiency intake and exhaust. This system is best if you are working with flammable vapours in your shop. Air intake draws from outside and exhaust gas vents to the outside. As a result, there is no open flame like some other propane garage heaters. Another advantage to using a residential-style furnace when heating a garage is the air filter. The homeowner can add a HEPA filter to trap dust particles and help keep the garage work area and the furnace blower clean and dirt-free.

Warm air blows out of the top of the furnace from the plenum and through a single large vent. This two-stage gas furnace has a high and low setting on the gas burner. It also has a quiet two-speed induced draft blower. The blower can output 743 CFM on low and 939 CFM on high. The entire garage air exchanges once every 10 minutes. If the garage thermostat is set for a lower temperature when not in use, it won’t take long to heat the garage to a higher temperature when needed.
Step 20 : Run furnace.

Bulletin – Indoor Air Quality for Residential Buildings

Air Filtration and Indoor Air Quality - Unionville Heating and Air Conditioning

Unionville Heating and Air Conditioning is continuously monitoring and gathering information to provide their customers with the best recommendations and implementation for residential HVAC systems.  Our goal for learning about advancements in technology is to apply these learnings to help keep us all safe. We care!

This bulletin is issued by ASHRAE to address the COVID-19 pandemic and it’s effects on HVAC

The American Society of Heating, Refrigerating and Air-Conditioning Engineers, (ASHRAE) is a global professional society of over 55,000 members committed to serve humanity by advancing the arts and sciences of heating, ventilation, air conditioning, refrigeration and their allied fields. ASHRAE has established a Task Force to help deploy technical resources to address the challenges of the COVID-19 pandemic and possible future epidemics as they relate to the effects of heating, ventilation, and air-conditioning (HVAC) systems on disease transmission. Guidance and building readiness information for different operational conditions have been developed for several building types, including commercial; residential; schools and universities; and healthcare facilities.

Home is usually the safest indoor space and we stay there as much as possible to protect ourselves and to help mitigate the spread of COVID-19. ASHRAE recommends following CDC guidance on minimizing contact, wearing cloth face masks and creating a household plan. ASHRAE’s residential building guidance supplements the CDC guidance with general recommendations for minimizing virus transmission through the air using the home’s HVAC equipment and controls. ASHRAE’s website provides additional details and the most up-to-date information on residential buildings, as well as answers to Frequently Asked Questions. Please consult the full guidance for important details and consider reaching out to qualified design professionals for detailed analysis as needed.

  • Maintain thermal comfort: Avoid extremes of temperature by operating and maintaining the building and the heating and cooling equipment to keep temperature and humidity in normal ranges, which are generally 68-78 Fahrenheit (20-25 Celsius) and 40-60% relative humidity.
  • Filtration for Homes with Forced-Air Systems: Upgrade filters to high-efficiency filters (MERV 13 or the best the system can accommodate), if practical. Adjust the fan setting to run even if not currently heating or cooling.
  • Ventilation (with outdoor air): Increase mechanical ventilation, if practical. If the house is not equipped with a mechanical system that provides whole house ventilation opening multiple windows is an acceptable alternative for a single-family home. Whole-house “summer cooling” fans or economizers may also be used to increase outdoor air ventilation. Weather may make this impractical at times.
  • Restrooms: Operate exhaust fans in bathrooms, toilets and lavatories preferably continuously. Toilet lids should normally remain closed, especially prior to flushing. Do not allow plumbing traps to become dry.
  • Air Purifiers: Stand-alone air cleaners (often called air purifiers) with HEPA particle filters can help remove suspended small airborne particles that can contain viruses and the fine particles typical of wildfires. When either is a risk, operate the device(s) continuously. In general, the larger the flow the better. Those with ultraviolet disinfection can further reduce virus risk.
  • Multi-Family Homes: Minimize the use of open windows to limit the potential transfer of infective air from nearby apartments. Seal any large openings in walls or ceilings or gaps around plumbing or electrical penetrations that could allow air to flow into the dwelling unit from other units in the building.
  • Create an Isolation Space for Infected Household Members: Barriers should be used between the isolated and common spaces. The isolation space should have flow into it from other spaces which can be achieved using exhaust fans temporarily installed in windows or bathroom exhaust fans if the isolation space has its own bathroom. Air purifiers should be considered.
  • Create a Protected Space for High-Risk Household Members: Barriers should be used between the protected and common spaces. The protected space should have air flow out of it to other spaces which can be achieved using supply fans temporarily installed in windows. Air purifiers should be considered.

The information above is provided as a service to the public. While every effort is made to provide accurate and reliable information, this is advisory, and is provided for informational purposes only. They are not intended and should not be relied upon as official statements of ASHRAE.

Government of Canada COVID-19: Guidance on indoor ventilation during the pandemic

Replace filter with a high MERV rating

The Public Health Agency of Canada (PHAC) has developed a guide to inform Canadians about how indoor ventilation, combined with other recommended public health measures, can reduce the spread of COVID-19. The guide also provides practical tips on improving indoor air, ventilation and filtration to help reduce the spread of COVID-19.

The complete content of this guide is available on the Government of Canada website.

Please read the key messages

  • Limit indoor gatherings
  • Open windows and doors
  • Consult an HVAC professional
  • Consider avoiding the area

Influence of ventilation on risk of aerosol transmission

If a person who is infected is in an indoor space, build-up of viral particles will depend on:

  • how infectious the person is
  • the activities the person undertakes
  • the size of the space and its ventilation

The smaller the room, the faster the build-up of particles containing SARS-CoV-2 virus. In larger spaces, it may take longer for virus-containing aerosols to build up throughout the room. Good ventilation will:

  • move outdoor air into the space
  • dilute potentially contaminated air
  • remove contaminated air through vents or open windows

In any size of room, close proximity can result in high-risk exposure, regardless of ventilation.


There are many ways to improve ventilation to mitigate the transmission of infectious diseases. The most appropriate measures depend on the characteristics of the particular setting. One way to improve ventilation is by opening exterior doors and windows for a few minutes, ideally with more than one open at a time.

Opening windows in winter may not always be comfortable or possible. Doing so for a few minutes at a time during the day can still improve air quality, with minimal impact on the indoor temperature. If occupants will be indoors for longer periods, for example at schools, occupants should have regular outdoor breaks, to allow for ventilation of the room.

An HVAC system will exchange indoor air a certain number of times per hour as a part of regular operation. To increase ventilation, run your HVAC system fan continuously at a low speed to provide air movement and filtration without unwanted draft. Within non-residential buildings, run the system for 2 hours at maximum outside airflow before and after the building is occupied. Bathroom and kitchen exhaust fans that are vented to the outside can also be used to help remove potentially contaminated air, where appropriate.

Most HVAC systems will recirculate some air through the indoor space, making it important to:

  • ensure that filters are well sealed without a bypass
  • clean or change your filters regularly per manufacturer’s recommendations
  • select filters with higher MERV ratings that are more efficient at removing particles

This should be done within the specifications of your HVAC system and in consultation with an HVAC professional.

Portable or ceiling fans, or single unit air conditioners may circulate air within the room, but they do not exchange air or improve ventilation. If using a window air conditioner unit or a fan is necessary, aim the air stream away from people to reduce the spread of potentially infectious droplets or particles.

Please contact us if you have any concerns or questions about how to improve your indoor air quality.  We are happy to provide a free no-contact consultation.

Paperless Business is Green and Efficient

paperless office at Unionville Heating and Air Conditioning

John St. Germain was interviewed after Unionville Heating and Air Conditioning won the Reader’s Choice Awards. Read the article on Markham Review

From tap debit cards to Apple Pay and e-transfers to direct withdrawals, cash is playing less and less of a role in commerce today.

One Markham business is looking to do the same thing with paper.

After a two-year long migration process, Unionville Heating and Air Conditioning has gone completely paperless—an effort spurned by a desire to reduce both the company’s carbon footprint and operating costs.

Now in its 32nd year, the award-winning residential heating and air conditioning installation and service company has eliminated its paper trail not only for invoices and purchase orders—but even promotional materials like brochures and business cards.

For the majority of the company’s 14,000 customers, dealings—including quotes, invoices and receipts—are electronic.

Unionville Heating and Air Conditioning president John St. Germain said that they’ll still make accommodations for non-connected customers, in particular computer-less elderly clients, but most have welcomed the change.

“It’s either you keep up to the crowd or you fall behind,” St. Germain said. “It’s one or the other. At the end of the day, everybody else is moving forward. Times are changing, and where people pick up the telephone and make phone calls these days to say ‘Hi, how are you?’—those days are gone. They’re texting now, and sending emails.”

The company tested out an automated phone system, but scrapped the service last month on account of it being too impersonal.

It was one of a few missteps along the way for the company that decided to undertake this evolution on its own.

St. Germain—who, ironically, describes himself as “old school” with technology—and his team decided to keep the process organic rather than hiring a consultant.

Though “a few mistakes” were made, he said that the cost savings—and final product—make it worthwhile.

“The whole idea behind going electronic and putting everybody on computer systems or tablets is to reduce our costs so that we can keep that reduction and pass it on down to our consumers,” he said. “We try to do our best to save the customer some money and stay in business.”

One major phase of the process was the closure, and subsequent decentralization, of the company’s Unionville office, spurned by a spike in rent costs when a new landlord took ownership of the office’s building.

Now, the company’s employees work from home—cutting down on commuting time and costs—with service technicians going directly from home to customers rather than making an unnecessary trip to the office beforehand.

Without paperwork to pick-up and drop-off, this is much easier to facilitate.

Beyond the environmental and economic impacts, St. Germain said it has also simplified the business a fair bit.

Under the previous model—which involved a lot of paperwork being mailed—things were lost and wires were crossed. Now, he says, things are much more streamlined.

“I don’t confuse my customers, I don’t confuse myself, and we stay efficient,” he said.

Furnace Backup Power During Electricity Outage

Get backup power to your furnace during a power outage

Get backup power to your furnace during a power outage.

All you need is CarGenerator™ and an extension cord.  When the power goes out due to high winds, heavy rain or ice, just plug in CarGenerator.

You already own 75% of a backup generator, sitting right there in your driveway! Add CarGenerator to your vehicle, and you have the world’s most reliable, longest running, ultralight, no maintenance backup power solution.

Your car equipped with CarGenerator is a backup generator and will run 1000W of appliances and devices.

  • Your home furnace and sump pump, to keep your house warm and dry when the power goes out.
  • Your fridge, to keep the food (and beer) cold in the summer weather
  • A few lights and TV’s, computers, and more
  • Medical devices: if you haven’t been camping in a while because you need your CPAP, oxygen machine, and other medical device, now you can go!

Modern furnaces are constructed with electronic circuit boards and are sensitive to the quality of electrical power.  Like most electronics a furnace requires pure sine wave clean power. CarGenerator provides this type of power which makes it safe to run with sensitive electronics.

How much power can this provide?

The amount of power provided varies by vehicle. The first and most important goal is to power your gas furnace to keep your house warm. CarGenerator testing shows that a typical furnace needs between 100-400 watts of solid power to run. After that everything else is a bonus up to the maximum your vehicle can provide. Once your furnace is running and you see how much power it uses, you can then add cellphone chargers, laptops, ipads, tablets, computers, a few lights, fridges and freezers depending on what your car provides. You can also rotate devices in shifts, so plug in fridges/ freezers for a few hours then switch to power other devices for a few hours to maximize your available power.

Unionville Heating and Air Conditioning is currently offering a discount on the all CarGenerator All Weather 1000W unit (regular price $895) for purchase at $795 when accompanied by a new furnace purchase.

Spring Air Conditioning Service

A message from the President of Unionville Heating Ltd. John St Germain

Important Information To Customers

We remind you to obtain a spring air conditioning service.  Perform an AC service now.   It is most important for units that are builder installed and over 3 years old without ever being serviced.  You could be in for a long wait when the first heat wave arrives in Ontario and your unit doesn’t work.

We receive the same phone calls every year for the last 35 years from customers saying “We had our unit installed 3 years ago and now it’s not working. We called the guy but he is not answering his phone or the number is out of service. My AC unit is still under warranty”

You can save money on the original purchase by buying the lower priced model from an entry level contractor. As a result,  homeowners will now need to spend more money to get the system working properly or replace it altogether.

Get cooled off, Not ripped off

This year is very different from years past, due to the outbreak pandemic.

Now more than ever is the time that we need our air conditioning systems working at their peak performance.  Service your AC unit before the upcoming summer months by a reputable company you see in the community.

Our company usually starts our spring air conditioning service in mid-April.

Covid-19 has changed that.

We service our contract customers’ units by cleaning, testing and running efficiently before the heat hits.

Your home is your castle this year in particular.  People are spending less money on travelling.  Isolation orders have changed our lives.

Be proactive now and stay ahead of the curve.  Decide to have your air conditioning serviced for this cooling season if it’s been over three to five years.

As the owner of Unionville Heating, I see the rush hit every year.

People wait for the first heat wave and end up last in line for service from a qualified and respected company. In light of that, some people opt to work with any contractor, one that can be in your home in a few hours. Unfortunately for these customers, they set themselves up for disappointment and waste their money on cut rate pricing and poor workmanship.

Skilled labour is not cheap and cheap labour is not skilled.

Plan ahead, do your research and you’ll find that our company will be here to take the best care of your home and your family because “WE CARE”

Indoor Air Quality and Safety during COVID-19

Spring Air Conditioning service, air circulation improves Indoor Air Quality

Spending More Time Indoors Due to Self-Isolation

With regard to COVID-19 and the effects on people in our community, President of Unionville Heating John St.Germain says,

“We care about our staff, and we care about our customers. Unionville Heating and Air Conditioning is open for business and here to help. We are spending more time in our homes now, more than any other time over the last ten years.  As a result of spending all this time inside, Indoor Air Quality (IAQ) is an important issue that customers need to know about.  Proper ventilation, filtration and cleaning are necessary to be healthy and safe indoors.”


The Government of Canada provides information about ways improve or maintain good IAQ.

Here are 8 things you can do right away to improve the air quality in your home:

  1. Make sure your furnace is well-maintained to prevent carbon monoxide (CO) accumulation.
  2. Change the furnace/AC filter regularly. It is important to replace or clean filters regularly as per manufacturers’ instructions. Removal rates for filters can change over time. Don’t forget about other portable air filters in the house.
  3. Use the exhaust fan in the bathroom when showering or bathing to reduce humidity and prevent mould growth.
  4. Use your range hood to reduce your exposure to pollutants from your gas stove such as nitrogen dioxide (NO2) and humidity from cooking activities.
  5. Install at least one CSA-approved carbon monoxide (CO) alarm close to bedrooms.
  6. Ventilate your home by making sure there is good air circulation and control the humidity.
  7. Outdoor particulate matter levels may often be higher than indoor levels. Therefore, natural ventilation (from an open window or door) may not always be effective in reducing indoor levels. This is especially the case on poor air quality days, so use an air conditioner when it is smoggy outside, if possible.
  8. Regular house cleaning using a mix of methods can help improve indoor air quality. Keep your rugs and carpets clean.  Clean hardwood and tile floors with a damp mop.


Spring Service

Servicing your air conditioning unit at some point in the near future will likely become necessary.  There is typically a rush when the first hot day arrives.  That’s usually the first nice warm day in the spring where everyone will want to turn on their air conditioning units.  It’s at that point Unionville Heating receive requests for an incredible amount of service calls.

John is hoping that customers will take a proactive approach with regards to keeping safe, and offered this advice to homeowners with AC units,

“If this physical distancing and isolation continues into the late summer as some are predicting, the last thing we want on the first heat wave, is 300 ‘no-cooling’ phone calls. People need to know they can pre-book their AC service on-line and stay ahead of the curve. If we all do our part, we can help to flatten the curve and provide a healthy environment to our customers while in isolation in their homes over the next few months.”


To keep us all safe, Unionville Heating has prepared this information we would like you to know:

  • Our staff is trained and have all the necessary tools to protect themselves, their families and our customers.
  • Important! Safety is our first priority in responding to any service call.


We have developed the following processes to ensure we all stay safe:

All customers calling in for service must follow our safety processes or we will reserve the right to refuse service.


Process at time of booking:

Answering the pre-appointment questions:

  • Has anyone in the home been out of the country in the last 2 weeks?
  • Have they been in the company with anyone who has been out of the country in the last 2 weeks
  • Is anyone in the house sick or coughing?


Process for service call at your home:

  • Everyone maintains a 2 metre distance from our techs while in their homes.
  • The customer must prepare and sanitize all door entries to the furnace and outdoor A/C units.
  • Absolutely no contact by shaking hands or coughing or sneezing within the 2 metre distance.
  • The company will supply any and all protective gear and or disinfectants necessary to do our job safely.
  • When we arrive to your home, we call you from the driveway and ask to allow us entry and to be sure we are aware of our social distancing and safety process.
  • We will send an invoice after the service or you can pay by e-transfer

Maintain Good IAQ in Your Home

As a result of self-isolation, the indoor air quality of our homes has become a more important issue since we are spending more time indoors.  Unionville Heating can provide your spring air conditioning service in a safe way and in a timely way if you schedule your appointment before the rush.

Call our office (905-479-1290) or book online.
