We have used Ashton for duct cleaning service in the past so it was our only call to get the job done this year. From the warm reception to our phone call until the ducts were cleaned today the communication was excellent. The quality of the service provided by Josh, your service technician, was exceptional. The level of service provided from initial contact to job completion is the reason we chose Ashton again. If you want quality service at a fair price contact Ashton. Ted.

AC Services We Offer in Ajax

Air Conditioner Repairs

When your AC stops cooling, short-cycles, trips the breaker, or quits on the hottest day, we’re there in a hurry.

Common culprits in Ajax: refrigerant leaks in older systems, capacitor failures during heat waves, and undersized units straining in bigger two-storey homes.

We find the real problem with advanced diagnostics, explain what caused it, and if it makes sense we repair it with transparent flat-rate pricing- we don’t upsell unnecessary replacements.

Our Diagnostic Service Calls are $135+HST. Parts and Repairs are extra.

Air Conditioner Sales and Installation

We offer free no-pressure, in-home AC installation consultations in Ajax.

We size your system based on what your home actually needs- so you get the whole home comfort you deserve.

HVAC Appliance purchases are a big decision that you should feel confident about. Get personalized options that fit your needs and budget, with everything explained so you can make the right choice.

Central Heat Pump Cooling

Heat pumps heat and cool your home from one system and Ajax’s newer, well-insulated builds are often perfect candidates.

But we won’t recommend one unless it makes sense for your home. We’ll honestly assess whether a heat pump works for you, what backup heat you need, and whether your ductwork and insulation are ready or need upgrades first. You may even qualify for grants up to $5,000.

Ductless Heat Pump Split Systems

Ductless split systems heat and cool without needing ductwork. Ductless split systems are ideal for Ajax’s older homes or when you need to cool a specific room or space that’s hard to keep comfortable. We’ll explain the pros and cons honestly and help you decide if a ductless system makes sense for your home. No pressure, just straightforward advice so you can make a choice you feel confident about.

If you require expert advice on AC repair in Ajax, our knowledgeable team is here to help.

Aeroseal Duct Sealing For Uneven Cooling and Airflow

Second floor too hot? Basement never right? That one room upstairs that won’t cool? This is common in Ajax’s bigger homes and older homes with leaky ductwork.

A bigger AC unit usually won’t fix it. We’ll check your damper settings and duct connections first, then honestly assess whether Aeroseal Duct Sealing is right for you. It seals up to 90% of ductwork leaks in one visit, includes whole-home duct cleaning, and works from the inside out.
