The 5 Best Contractors for HVAC in Oakville

It is inevitable that, at one point, every homeowner will require the work of an HVAC contractor. These contractors are professionally trained in many areas of home comfort. HVAC  stands for heating, ventilation, and air conditioning. These systems can include boilers, furnaces, water heaters, and air conditioners. Along with those often necessary HVAC systems are many other areas of home comfort. These all require trained and licensed HVAC professionals when it comes to installations, repairs, and maintenance as well.

And when you are ready to choose the right contractor for your home, the number of contractors in the GTA might make the process overwhelming. Along with our list of the best contractors for HVAC in Oakville, we provide a guide to choosing the right HVAC contractor. This guide may also help select contractors for other home renovation projects.

Finding the right HVAC contractor for your home comfort needs

There will be many ways to assess which contractor is right for you. Below is a list of things to look for in your following HVAC contractor.

Training and credentials

Never hesitate to inquire about a contractor’s training or credentials. Regarding residential HVAC, technicians must be certified to perform installations, repairs, and maintenance. Ontario considers these “Heating, Refrigeration, and Air Conditioning Technician” certification programs. This is considered industry training. Plus, many HVAC contractors will have technicians with factory-specific training. This gives technicians specific training on different HVAC brands and manufacturers. Additional credentials to look for could include awards, further training in HVAC-related areas, or additional safety training.

HVAC services offered

Some HVAC contractors focus closely on furnace, water, or boiler heating, ventilation, and air conditioning. There are also contractors for HVAC in Oakville which offer a variety of other HVAC services. For example, one company might specialize in heat pump conversion. The one you hire for your home comfort will, of course, depend upon the services provided by each contractor. In addition to repairs, installations, or maintenance for the more common HVAC systems, homeowners may require a contractor for gas fitting (gas furnaces, fireplaces, garage heating), appliance installation, or creating a more energy-efficient home.

Payment options or flexibility

HVAC investments are, at times, significant. Many contractors in the GTA and Oakville area recognize the high cost that can come with a brand new air conditioning system, furnace replacement, or hot water heater replacement, for example. HVAC contractors may offer various ways to help keep everything within budget. Those could include financing options, different payment plans, promotions and discounts, or government green home incentive grants.


Even with a brand new HVAC company, the technicians and owners likely have experience through previous work or education. An HVAC contractor’s expertise is usually accessible through the company website or online presence. This could look like online reviews, website information, or online portfolios. Never hesitate to ask about your experience or any of these parts of an HVAC company. Owners, technicians, and other professionals are likely happy to share this information.

Customer Feedback

My husband and I bought a new house, but the one thing it was missing was a finished basement. We were determined to add an extra bedroom, a living room, and a laundry room, but our skills didn’t take us so far. Eventually, we buckled down and decided to hire somebody to finish this up for us. Damon was the clear choice and he was such a pleasure to work with. Our basement is our new favorite spot! Thanks Aireno!
