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 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!

I had an issue with my Rheem furnace not heating, so I reached out to HVAC-group for assistance. The technician was quick to identify the problem as a faulty flame sensor. The service was prompt, efficient, and ultimately effective. I'm very pleased with their work and would highly recommend their services to anyone facing HVAC issues.

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.

Old AC Costing You More? Here’s When to Upgrade

Frequent Breakdowns

If your AC constantly needs repairs, from capacitor failures to compressor malfunctions, a replacement may be more cost-effective than ongoing service calls.

Costly Repairs

Major fixes like compressor replacements, refrigerant leaks, or motor failures can add up. If repair costs approach the price of a new unit, upgrading makes financial sense.

Poor Cooling Performance

If your AC struggles to reach or maintain the set temperature, issues with refrigerant levels, coil efficiency, or thermostat calibration could indicate it’s time for an upgrade.

Inconsistent Airflow

Hot and cold spots in your home may be caused by failing blower motors, leaky ducts, or restricted airflow. A new system with proper ductwork optimization ensures even cooling.

Outdated or Inefficient System

Older AC units with low SEER ratings and single-stage compressors waste energy. Upgrading to a high-efficiency model reduces electricity use and enhances cooling.

Rising Energy Bills

Aging systems lose efficiency over time, forcing them to work harder. High-SEER-rated ACs with variable-speed compressors reduce energy waste and operating costs.

Strange Noises

Unusual grinding, buzzing, or rattling sounds could mean motor wear, loose components, or a failing compressor—signs it’s time to consider a new system.

Unpleasant Odors

Musty or burnt smells from your AC could indicate mould in the condensate drain, electrical issues, or refrigerant leaks. A new unit ensures cleaner, fresher air.

Unit is Over 10-15 Years Old

Most ACs last 12-15 years. If yours is nearing the end of its lifespan, a new energy-efficient system will provide better cooling, improved air quality, and lower AC maintenance costs.

Frequently Asked Questions

How much should it cost to replace an AC unit?

The cost of replacing an AC unit varies based on system size, SEER rating, and installation complexity. In Mississauga, prices typically range from $3,000 to $7,500 for residential systems and higher for commercial units.

The $5,000 rule helps determine whether to repair or replace an AC unit. Multiply the cost of the repair by the age of the unit—if it exceeds $5,000, replacing the system is often the better option.

Air conditioner installation costs depend on unit type (central, ductless, or commercial), ductwork modifications, and smart thermostat integration. Expect prices from $2,500 to $10,000 depending on system efficiency and home size.

 The 3-minute rule ensures compressor protection by preventing rapid on-off cycling. If an Air conditioner is turned off, wait at least 3 minutes before restarting to avoid pressure buildup that can damage the unit.

After ac installation, wait at least 24 hours before turning on your new AC if it was placed on its side during transport. For standard installs, a technician will ensure the system is ready to run immediately.

Proper AC sizing depends on home square footage, insulation levels, window placement, and climate conditions. Our experts perform manual J load calculations to determine the ideal system for your space.

 A standard central AC installation takes 4 to 8 hours, while a ductless mini-split setup may take a full day. Complex projects, like zoning system integration or duct modifications, can take longer.

Yes, most municipalities, including Mississauga, require a permit for new air conditioner installations to ensure compliance with building codes and energy efficiency standards. We handle all necessary permits.

A new energy-efficient AC lowers utility bills, improves cooling performance, reduces noise levels, and enhances indoor air quality. It also prevents costly repairs and increases home resale value.

AC installation requires electrical connections, refrigerant handling, and ductwork integration, which should be performed by a licensed HVAC professional to ensure efficiency, safety, and warranty coverage.
