HVAC problems?

Do you have HVAC problems? Get comfortable finding a contractor

It keeps you warm in icy winter and cool in the summer heat, but how much do you really know about your HVAC? Sure, you control it with the thermostat on your wall, but let’s face it, there was also a time you weren’t entirely sure what HVAC stood for. Don’t worry, you’re not the only one (it’s Heating, Ventilation and Air Conditioning, by the way).

While the ‘heat’ and ‘cool’ options are simple, your HVAC is actually quite a complex system. That’s why it’s important to choose a qualified professional when it comes to installation, replacement, and upgrades. To help give you the edge on finding a contractor, we asked Warren Heeley, president of the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI), what homeowners need to know.

What’s the difference between qualified and unqualified contractors?
With the complexity of the equipment and the training requirements dictated by the province, qualified HVAC contractors must have proper licenses to cover both the business and their individual technicians, as well as insurance to protect themselves and their clients. Certified contractors can also offer energy-efficiency rebates to help offset some of the costs for upgrading to new equipment.

How can homeowners make sure they’re dealing with a qualified professional?
A little research goes a long way. When you talk to potential contractors, explore their qualifications to ensure they can get your job done right. The performance level of your HVAC system is directly related to how well it’s installed, so it’s good to learn what needs to be done to your HVAC system, the range of available systems, and what you should be looking for. Then get a quote from at least two or three contractors and make sure these companies provide you with thorough information about their recommendations and qualifications.

What problems do you face using an unqualified contractor?
If you use an unqualified contractor, you take the risk that your HVAC won’t operate properly. This can result in a variety of problems from uncomfortable temperatures to increased energy use. In addition to making your dollar spend worthwhile, it’s comforting to know that qualified heating and air conditioning contractors must comply with a range of different regulations related to energy, safety standards, and environmental requirements on an ongoing basis.

What does price have to do with finding the right HVAC contractor?
There can be a significant cost involved to ensure an HVAC system is installed and operating properly. If you get quotes from qualified contractors, they should be in the same price range. If one of the prices is significantly lower than the others, remember that ‘if it sounds too good to be true, it probably is.’ And don’t be afraid to ask questions and negotiate if you don’t think the price is right.

What’s ultimately at stake here?
When it comes to your HVAC, you’re investing in a core piece of your home that will last between 10 to 20 years – if it’s installed properly. By taking the time to find a qualified contractor, you can be confident the hard stuff was taken care of by a pro and focus on impressing everyone with your comfortable home.
