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.

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.

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.

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.

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.

Regulations Amending the Energy Efficiency of Gas Furnaces

Regulations Amending the Energy Efficiency Regulations

Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) has sent a message to manufacturers and installers of gas furnaces in Canada.

What this means to Canadian consumers:

Gas furnaces installed in Canada effective December 12, 2019 must meet the new minimum requirements as described in the Energy Efficiency Act. Consumers need to be aware that less efficient units may be flooding the market in manufacturer’s attempts to liquidate their old stock.

Message from the HRAI: This message is intended to clarify the new requirements for residential gas furnaces contained in Amendment 15 to the federal Energy Efficiency Regulations, which was published in the Canada Gazette II on June 12, 2019. NRCan has advised HRAI that they have been hearing about some confusion in the field about the new requirements.

The federal government has set the new minimum standard for gas furnaces at 95% AFUE. Effective December 12, 2019, any product with a date of manufacture after July 3, 2019, must meet the 95% AFUE level.

As an example, after December 12, 2019, a 90% AFUE furnace that was manufactured on August 2nd cannot be shipped into the country or across provincial borders for the purpose of sale or lease.

For product manufactured in Canada, shipments will be subject to the federal regulation at any provincial border. Where provincial regulations exist for those products, they would apply well.
