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!
Response from the owner 22:00 04 Jun 25
Thank you so much for the wonderful 5-star review! We’re thrilled to hear you were happy with your Lennox AC installation experience. We understand how important a cool home is—especially with a newborn—and we’re glad we could respond quickly and get everything running smoothly in just two days. Yura and Yuriy truly appreciate your kind words. We’re always here when you need us, and we look forward to helping with your future maintenance needs. Thanks again for trusting HVAC Group!

I came from vacation to a broken furnace and a cold house. I called HVAC group late at night and they were able to send someone the next morning.

Technician was very professional, found that I had an igniter problem, had a spare part with him and solved the problem within an hour.

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.

How to Tell If Your Air Conditioner Needs Professional Attention

Insufficient Cooling

If your AC fails to maintain set temperatures, it could indicate refrigerant leaks, dirty evaporator coils, or a malfunctioning compressor. Professional diagnostics can pinpoint the issue.

Unusual Noises

Hearing buzzing, grinding, or squealing sounds? These noises may signal issues with the fan motor, blower assembly, or a failing capacitor needing immediate attention.

Weak or No Airflow

Obstructed air ducts, clogged filters, or a failing blower motor can cause poor airflow. Regular air conditioner maintenance ensures optimal airflow and prevents system strain.

Rising Energy Bills

Unexpectedly high energy bills may result from reduced system efficiency, caused by dirty coils, worn components, or an improperly calibrated thermostat.

Water Leaks or Excessive Moisture

Leaking AC units often indicate clogged condensate drains or damaged drain pans. Excessive moisture can also stem from refrigerant issues, requiring professional inspection.

Bad Odors

Musty smells signal mould or mildew in the system, while burning odours could indicate overheating electrical components. Address these issues promptly for better air quality.

Frequent Cycling On and Off

Short cycling may result from thermostat miscalibration, improper system sizing, or a failing compressor. This can lead to energy waste and premature wear.

Poor Indoor Air Quality

Dust, allergens, and pollutants may enter your home if air filters, ductwork, or ventilation systems are not functioning properly. Professional care ensures cleaner, healthier air.

Thermostat Issues

Inaccurate or unresponsive thermostats can disrupt cooling. Issues may include sensor misalignment, outdated technology, or electrical malfunctions.

Age of the System

Systems older than 10-15 years may struggle with efficiency, outdated SEER ratings, and frequent repairs. Upgrading to a modern unit can reduce costs and improve performance.
