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 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.

Types of Water Heaters We Service – Electric, Gas, And Others

Traditional Tank Water Heaters

We service standard tank water heaters, ensuring anode rod protection, thermostat accuracy, and sediment flushing. Our preventative maintenance extends lifespan, improves efficiency, and prevents breakdowns.

Tankless Water Heaters

Tankless systems require descaling, flow rate optimization, and heat exchanger cleaning. We prevent mineral buildup, ignition failures, and pressure issues, ensuring continuous hot water and energy savings.

Electric Water Heaters

We inspect heating elements, thermostats, wiring, and insulation to ensure your electric water heater runs at peak efficiency. Routine maintenance reduces power consumption and extends system life.

Gas Water Heaters

Gas water heaters need burner inspections, pilot light adjustments, and venting checks for safety. We ensure proper gas flow, carbon monoxide protection, and combustion efficiency to prevent hazards.

Hybrid Models

Hybrid water heaters use heat pump technology for maximum efficiency. We service compressors, refrigerant levels, and heating elements to ensure optimal performance, energy savings, and extended system life.

Signs Your Water Heater Needs Maintenance – Don’t Ignore These Red Flags!

Fluctuating Water Temperature

Inconsistent water temperature signals thermostat failure, sediment buildup, or a failing heating element. Our technicians diagnose and calibrate your system for steady, energy-efficient heating.

Loud noises indicate excessive sediment buildup in the tank, causing overheating and stress on components. We flush out debris, inspect the anode rod, and restore efficiency before damage worsens.

Rusty or brown water indicates corrosion inside your tank or a failing anode rod. Our experts replace worn components, flush the system, and restore clean, safe, high-quality hot water for your home.

Leaks can stem from excessive pressure, a failing pressure relief valve, or internal corrosion. Our team seals fittings, tests valves, and prevents further water damage with expert servicing.

An inefficient water heater works harder, consuming more energy. Our comprehensive tune-ups optimize burner efficiency, calibrate thermostats, and remove obstructions, lowering your monthly costs.

Frequently Asked Questions

What maintenance should you do on a water heater?

Regular maintenance includes flushing sediment buildup, testing the pressure relief valve, inspecting the anode rod, checking gas and electrical connections, and calibrating the thermostat.

While you can flush a water heater yourself, improper draining can damage heating elements or leave sediment behind. A professional service ensures thorough flushing, safety checks, and efficiency optimization.

If your water heater is over 10 years old, flushing may not be effective if the tank is heavily corroded. A professional inspection can determine whether a flush or a replacement is the best option.

Signs include fluctuating water temperature, unusual noises, rusty water, rising energy bills, or visible leaks. If you notice these issues, a professional inspection is recommended.

Flushing removes sediment buildup while draining only empties the tank. Flushing is the best method to keep the system clean, improve efficiency, and prevent damage to heating elements.

Annual maintenance is recommended for tank water heaters, while tankless models should be descaled every 6 to 12 months, especially in areas with hard water.

Yes! Removing sediment buildup, checking gas/electrical connections, and calibrating thermostats helps your heater use less energy, reducing utility costs.

Without maintenance, sediment buildup, corrosion, leaks, and efficiency loss can lead to higher energy bills, unexpected breakdowns, and costly repairs or replacements.

Yes, tankless systems require descaling to remove mineral deposits that reduce efficiency and block water flow. Without maintenance, they can overheat or fail prematurely.

A standard maintenance service takes 60–90 minutes, depending on the unit type and condition. More complex tasks like anode rod replacement or deep descaling may take longer.
