Thanks buddy
Technician was very professional, found that I had an igniter problem, had a spare part with him and solved the problem within an hour.
Reasonable pricing and very professional. Highly recommended!!!
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.
Fast AC Solutions
Our Comprehensive AC Maintenance & Tune-Up Services
Complete System Inspection & Function Testing
HVAC Group run full diagnostic tests on your air conditioning unit, checking compressor strength, refrigerant levels, and airflow to catch any problems early before they grow into major repairs.
Air Filter Cleaning or Replacement
Dirty filters reduce cooling and air quality. We clean or replace your system’s filters — whether HEPA, pleated, or standard — to restore airflow and improve efficiency.
Evaporator & Condenser Coil Cleaning
Dusty coils can choke your system. We scrub buildup off the evaporator and condenser coils to increase energy efficiency and lower operating strain on your AC.
Refrigerant Pressure Check & Leak Testing
Low refrigerant equals weak cooling. We measure charge levels, find leaks, and top up refrigerant (R-410A, R-32) to restore cool air and protect your compressor.
Thermostat Calibration & Smart System Testing
We adjust your thermostat for precise control and inspect smart or zoned systems to make sure you get even, consistent temperature throughout your home.
Ductwork Inspection & Airflow Balancing
Leaky or blocked ducts reduce cooling and waste energy. We inspect and adjust ductwork, vents, and returns to maintain even airflow and room-to-room comfort.
Electrical Connection & Safety Checks
Loose wires can cause shorts or fire hazards. We test capacitors, contactors, breakers, and wiring connections for safe and reliable operation.
Blower Motor & Fan Blade Cleaning
A dirty blower or misaligned fan blade affects air movement. We clean, lubricate, and test your blower system for steady airflow and reduced wear.

When to Schedule AC Maintenance – Key Warning Signs
Sometimes your system tells you it’s time for a home air conditioner tune-up — if you know what to watch for.
Weak Airflow
Poor airflow could mean blocked ducts or a blower issue.
Strange Smells
Musty or burning smells may indicate mould, wiring problems, or dirt buildup.
Warm Air
If your AC blows warm air, it could be a refrigerant or thermostat problem.
High Energy Bills
A spike in your hydro bill means your AC might be working overtime.
Frequent Cycling
If your AC keeps turning on and off, it’s likely overdue for a tune-up.
Noisy Operation
Rattling, grinding, or banging usually signals worn or loose parts.

An AC should reduce indoor humidity — if it doesn’t, call us.

Frequently Asked Questions
What maintenance should be done on an AC unit?
Maintenance includes filter cleaning, coil inspection, refrigerant level checks, thermostat calibration, ductwork testing, and electrical safety checks.
How frequently should AC be serviced?
We recommend aircon servicing once a year, ideally in spring before peak summer usage. Commercial systems may need service quarterly.
How much does it cost to repair AC in Mississauga?
Air conditioning repair costs in Mississauga typically range from $150 to $700, depending on the issue. Contact us for a free diagnosis and honest pricing.
How often do I need to clean my AC?
Air filters should be cleaned or replaced every 1–3 months. Coils and internal components should be cleaned annually during your tune-up.
How do I know if my AC needs service?
Warning signs include weak airflow, warm air, high energy bills, strange noises, bad smells, or frequent cycling. If you notice any of these, call us.
What happens if AC is not serviced?
Lack of aircon servicing reduces efficiency, higher bills, poor cooling, system strain, dirty air, and potential breakdowns or part failures.
Is AC service worth it?
Yes — regular air conditioner maintenance extends system life, reduces energy costs, improves cooling, and avoids expensive repairs in the long run.
How often should AC gas be refilled?
Ideally, never use AC refrigerant (gas), which doesn’t run out unless there’s a leak. If cooling drops, we’ll check levels and recharge only if needed.
Is there anything I need to prepare before the technician arrives?
Just clear the area around the unit and make sure there’s access to your thermostat and electrical panel.
When is the best time for AC tune ups?
Spring is ideal — before your system has to work overtime in the summer.
