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 Your Water Heater Needs Repair – And How We Fix It

No Hot Water or Inconsistent Heating

A faulty thermostat, heating element, or gas valve can cause temperature fluctuations. We diagnose and repair electric, gas, and tankless water heaters to restore consistent hot water.

Water Heater Leaks & Tank Damage

Leaks can result from corroded anode rods, faulty pressure relief valves, or cracked tanks. Our experts identify leaks, repair damaged components, and recommend water heater tank repair or replacement.

Pilot Light Won’t Stay Lit

A failing thermocouple, gas control valve, or dirty burner can prevent ignition. We clean and replace faulty components to ensure safe and efficient gas water heater operation.

Discolored or Rusty Water

Rusty or cloudy water indicates tank corrosion or anode rod failure. We replace worn anode rods, flush the system, and check for internal rusting to improve water quality.

Strange Noises

Popping or rumbling sounds signal sediment buildup in the tank. Our technicians flush the system, inspect heating elements, and perform descaling to enhance efficiency and eliminate noise.

Smelly or Foul-Tasting Water

A bacterial buildup in the tank can produce a rotten egg smell. We treat the system with anode rod replacements, deep flushing, and water quality testing to eliminate odors.

Heater Taking Too Long to Reheat

Slow reheating can result from a damaged dip tube, thermostat malfunction, or weak heating element. Our experts replace faulty parts to restore fast and efficient water heating.

Water Pressure Issues

Clogged inlet valves, sediment buildup, or corroded pipes can reduce water pressure. We flush the system and clear blockages for steady, high-pressure hot water flow.

Frequently Asked Questions

Is it worth it to repair a hot water heater?

Yes, if the issue is minor, like a faulty thermostat, heating element, or pressure valve. If your unit is over 10 years old and frequently breaks down, replacement may be a better option.

The most common issues include no hot water, inconsistent heating, leaks, sediment buildup, and pilot light failures. These problems often stem from worn-out parts or poor maintenance.

Labor costs typically range from $300 to $1,000, depending on the heater installation complexity and type. Gas, tankless, or commercial water heaters usually require more labor than basic electric models.

Most tank water heaters last 8-12 years, while tankless models can last 15-20 years. Regular maintenance, such as flushing the system and replacing anode rods, can extend its lifespan.

Usually not. A water heater that old is less efficient, prone to leaks, and at risk of sudden failure. In most cases, a new energy-efficient model will save more money in the long run.

The main causes are corrosion, sediment buildup, pressure valve failures, thermostat malfunctions, and heating element wear. Lack of regular maintenance speeds up failure.

If you notice frequent leaks, rust-colored water, inconsistent heating, or rising energy bills, repairs may help. If it’s over 10 years old, a replacement may be more cost-effective.

Simple fixes like replacing the thermostat or flushing the tank can be DIY. However, gas valve issues, electrical repairs, and tank leaks should be handled by a licensed professional.

Most repairs take 1-3 hours, depending on the issue. Replacing heating elements, thermostats, or pilot lights is quick, while leak repairs or complex electrical work may take longer.

Yes! We provide 24/7 emergency water heater repair for leaks, no hot water, gas valve malfunctions, and pressure relief failures to restore hot water fast.
