The Importance of Regular Propane Furnace Servicing For Rural Homeowners in Surrounding Stouffville, Goodwood, and Uxbridge


For rural homeowners in the beautiful areas surrounding Stouffville, Goodwood, and Uxbridge, a propane furnace is a reliable, efficient, and cost-effective solution for heating your home. However, regular servicing is crucial to ensure your propane furnace continues to perform at its best. This article will discuss the benefits of regular propane furnace servicing and why it’s essential for rural homeowners like you.

  1. Maintaining Energy Efficiency

One of the main benefits of a propane furnace is its energy efficiency. Regular servicing helps maintain this efficiency by ensuring all components are clean and functioning optimally. Servicing helps reduce your energy consumption and keeps your heating costs under control.

  1. Prolonging the Lifespan of Your Furnace

Routine maintenance can significantly extend the life of your propane furnace. By identifying and addressing potential issues early, you can avoid costly breakdowns and keep your furnace running smoothly for years.

  1. Ensuring Safe Operation

Safety is a top priority when it comes to any heating system. Regular servicing of your propane furnace allows technicians to inspect critical components, such as the heat exchanger, burner, and venting system, for any signs of wear or damage. Propane furnace service helps ensure the safe operation of your furnace and prevents potential hazards like carbon monoxide leaks.

  1. Maintaining Consistent Performance

A well-maintained propane furnace delivers consistent heat, keeping your home comfortable throughout the colder months. In addition, regular servicing ensures that your furnace operates at peak performance, providing you with uninterrupted warmth when you need it most.

  1. Avoiding Unexpected Breakdowns

Unexpected furnace breakdowns can be costly and inconvenient, especially during winter. However, by scheduling regular maintenance, you can catch potential issues before they become significant problems, reducing the risk of sudden breakdowns and ensuring your home stays warm and cozy.

  1. Protecting Your Warranty

Many propane furnace manufacturers require regular servicing as a condition of their warranty coverage. Adhering to the recommended maintenance schedule ensures that your furnace remains covered under warranty, protecting your investment.


Regular servicing of your propane furnace is essential for rural homeowners in Stouffville, Goodwood, and Uxbridge. By prioritizing maintenance, you can enjoy the energy efficiency, safety, and consistent performance of a propane furnace while prolonging its lifespan and protecting your warranty.

If your propane furnace is due for servicing or you’d like to learn more about the benefits of regular maintenance, don’t hesitate to contact our team of HVAC experts. We’re here to help you keep your home warm and comfortable all winter long, providing expert advice and professional service you can trust.

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
- Level
- Shears
- Folding Bar
- Hand Seamers

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.

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.

Message from Unionville Heating and Air Conditioning President: COVID-19

Message from Unionville Heating and Air Conditioning President about covid-19

At Unionville Heating and Air Conditioning, the safety and well-being of both our Customers and our Service Technicians is always our top priority. Rest assured that we are actively monitoring the COVID-19 situation and are taking precautionary measures to aid in keeping our communities safe. As an essential service to our customers, we are committed to implementing best practices to help prevent the spread of disease and ensure we can continue to provide a high level of service.

We are confident in our plans to safeguard the health and safety of our customers and employees.  For more information about COVID-19, please visit Health Canada and Ontario Ministry of Health websites for ongoing updates.

To help with prevention, we are taking the following precautionary measures to protect our Customers

Addressing in-home customer service:

How we can all keep safe

Service Technicians will be keeping recommended safe social distance and will not be shaking hands with customers, as suggested by the Public Health Agency of Canada.  Our Service Technicians have been equipped with an ample supply of:

  • hand sanitizers
  • disinfectant wipes
  • masks
  • single-use gloves
  • boot covers

Any Service Technician who has flu like symptoms will be asked to contact the Public Health Agency and follow the COVID-19 testing protocol, including self-isolation where required.

Precaution questions

Customers need to inform us at time of placing an order if they are if they are sick or have been out of the country.  Have had any visitors to their home who have been sick. Are they in self isolation and for how long. Please be prepared to answer brief health and safety questions related to COVID-19 with our Unionville Heating and Air Conditioning Service Technicians

Instructions for a service visit

We are asking customers to wash and or sanitize all door entry handles.  All cheque payments should be put in a sealed envelope and given to the tech. We are following government protocol on social distancing and doing our part daily to flatten the curve as recommended by Health Canada.

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.

Cost to remove an old furnace

recycling old furnace and air conditioning parts

How much does it cost to remove an old furnace?

With Unionville Heating and Air Conditioning there is no additional charge to remove and dispose of your old HVAC parts.  We care about the environment and would not leave you with the burden of having to remove your old furnace.  Old furnace and A/C removal cost is free with Unionville Heating.

Once your new A/C or furnace is installed, we’ll take your old unit away.  You recycle every week at the curb side separating cardboard, cans and glass.  However municipal waste collectors will not pick up your old furnace or air unit.  Just because an item doesn’t belong in your recycling bin doesn’t mean that you can’t get rid of it responsibly.  Unionville Heating and Air Conditioning will do that for you.

We make sure your old furnace or air conditioning unit doesn’t end up in the land fill.  We separate the components and work with a recycling expert to ensure the materials enter the recovery stream according to the type of waste.

Unionville Heating has been recycling furnace and air conditioning units for over 35 years.  We have recovered close to 20 tons of refrigerant since then.

Regular maintenance benefits.

Regular inspection, old furnace repair, or replacement is important. Repairs will give you better furnace service life.  A new furnace will provide safe and cost-effective heating that you may not have realized you were living without.

Have your furnace and air conditioning unit serviced once a year. Find a company you trust and stick with them.  The cheapest guy on the block is probably not going to do the best job, so look for a professional, not just Jimmy down the street who is HVAC certified.  Keep records of HVAC service. One day if you sell the house, documents of well-maintained large components will help with the salability of the home.
