HVAC Group came recommended by a friend when our AC stopped working on a 38 degree day. We had called other services and either couldn't get through or everyone was booked. When I spoke to Yiri he said it was so busy they were booked until next week (which I expected as every other place said the same thing). But he stayed on the phone to ask a few questions about the unit. He was kind, and you can just tell when someone actually cares - he didn't have to talk me through the possible issues etc. He ended up sending someone out that evening who fixed it within 15 minutes. We are so appreciated of the service- both the actual work done and the customer care. Highly recommend. Thank you to both Yiris!

HVAC Group responded quickly and had my noisy air conditioner fixed within a day. Their professionalism and customer-first approach really stood out. They go above and beyond—highly recommended!
Response from the owner 03:37 11 Jun 25
Thank you for the great review! We’re glad we could help with your noisy air conditioner so quickly. When you contacted us about your Lennox AC making unusual noise, our technician arrived the same day and found the outdoor condenser was clogged and the fan motor was extremely noisy. Since the AC parts warranty was still valid, we replaced the faulty motor and thoroughly cleaned the unit to restore quiet and efficient operation.We appreciate you choosing HVAC Group for your local AC repair in Mississauga. Your comfort is our priority!

HVAC group has been absolutely fantastic to help us replace our air conditioner. From diagnosing to replacement took only 2 days (since the replacement unit was in stock). This is especially appreciated as the weather was getting hot fast and I have a newborn baby that cries in the heat. Yura is extremely knowledgeable and Yuriy installed the unit professionally with no interruption and minimal noise to our house’s activities. Thank you for your help! HVAC group comes highly recommended and I’ll be reaching out to them for routine maintenance!

Yuri is a true professional and is a very knowledgeable expert about furnaces.
I called him for advice when another well known Hvac company wrongly diagnosed my Trane furnace blower noise and told me I needed to undergo a $1500 repair. Yuri quickly assessed the problem and voila no more blower motor problems. All for $140!!
Thank you Yuri! I highly recommend your service, honesty and expertise.

Signs You Need a New Water Heater – Don’t Wait Until It Fails!

Lack of Hot Water

Inconsistent heating or sudden cold showers often indicate sediment buildup, failing heating elements, or a deteriorating dip tube. Our experts diagnose and replace your system for reliable hot water.

An aging water heater loses efficiency, working harder to heat water. Sediment accumulation, worn-out insulation, or thermostat malfunctions can spike energy costs. Upgrading reduces consumption and saves money.

A leaking water heater signals corrosion, faulty pressure relief valves, or internal tank failure. We inspect for cracks, replace worn seals, and install new, high-efficiency systems to prevent damage.

Banging, popping, or rumbling sounds stem from sediment buildup overheating the tank. This strains components and leads to inefficiency. Our specialists flush tanks or replace failing units for quiet operation.

Discolored or metallic-smelling water indicates anode rod corrosion or internal tank rusting. Ignoring it leads to leaks and contamination. We install corrosion-resistant models for long-term reliability.
