Why Ajax Homeowners Choose Walchuk Heating & Cooling
01

Every visit is handled by licensed, insured HVAC technicians who work on furnaces, air conditioners, heat pumps, and boilers every day. We are a fully licensed and insured mechanical company with TSSA recognition in fuels and BPV, so your equipment is serviced to Ontario safety and code standards. We follow proper procedures, use permits where required, and treat your home with care from the moment we arrive to the moment we clean up.
02

We explain what is going on in plain language, outline the options, and provide clear pricing before any work starts. There are no surprise add-ons and no pressure to replace equipment that can reasonably be repaired. You get straightforward advice so you can choose the solution that fits your home and your budget.
03
Local, Neighbourhood-Based Service
We are based just outside Ajax. That means shorter drive times, technicians who understand local home styles and climate, and a team that is easy to reach if you need follow-up. You are dealing with a nearby company that knows your community and provides HVAC services in Ajax, not a distant call centre.
04
The Right Solution for Your Home and Equipment
From older gas furnaces and traditional central air systems to newer high-efficiency heat pumps, we service and install a wide range of equipment and brands. That experience lets us match the solution to your home, how you use it, and your long-term plans instead of pushing the same product or brand in every situation.

Furnace Repair
When your furnace starts blowing cold air, making new rattling or banging noises, or constantly cycling without properly heating your home, it’s time to call the professionals at Walchuk Heating & Cooling. As a local Ajax and Durham Region HVAC company, we provide furnace repair that’s focused on clear communication, honest options, and getting your heat back on safely, without unnecessary upsells.
● No-heat and low-heat troubleshooting: Walchuk technicians track down the real cause of weak or no heat, whether it’s a safety switch, gas supply issue, or failing component, and get your system heating reliably again.
● Ignition, pilot light, and sensor repairs: We repair ignitors, pilot assemblies, and flame sensors so your furnace starts safely and stays running without constant resets or error codes.
● Blower motor, airflow, and control issues: If some rooms are cold or your furnace struggles to keep up, we inspect the blower motor, belts, filters, ductwork, thermostat, and control board to restore proper airflow and stable operation.
● High-efficiency gas furnace repairs: We service modern high-efficiency units, including condensate drains, pressure switches, and venting problems that can shut systems down.
Walchuk Heating & Cooling services all major furnace brands and provides fast furnace repair in Ajax, helping keep your home safe, comfortable, and warm through the coldest months.
Air Conditioner Repair
When your AC quits on a hot, humid day, you don’t just lose comfort, you lose sleep, productivity, and patience. Walchuk Heating & Cooling provides prompt, professional air conditioner repair in Ajax so you can get your cooling back. Our licensed technicians focus on clear explanations, solid repairs, and options that make sense for your home and budget.
● Warm air and poor cooling fixes: We diagnose why your system is blowing warm or barely cool air, checking everything from clogged filters and dirty coils to low refrigerant or failing components, and restore proper cooling performance.
● Frozen coils and airflow corrections: We address frozen indoor coils, blocked vents, and airflow restrictions by inspecting fans, coils, filters, and ductwork, helping your AC run smoothly without icing up or struggling to move air.
● Refrigerant leak detection and recharge: We locate and repair refrigerant leaks, verify pressures, and recharge the system to the correct level so your AC can cool efficiently and safely.
● Electrical and capacitor repairs: We troubleshoot and replace failed capacitors, contactors, relays, and other electrical parts that cause tripped breakers, buzzing units, or systems that won’t start.
● Short-cycling and no-start solutions: We get to the bottom of systems that keep turning on and off or won’t turn on at all, checking thermostats, sensors, safety switches, and control boards to stabilize operation.
Walchuk Heating & Cooling services all major AC brands and provides air conditioner repair in Ajax and the surrounding Durham Region. We diagnose issues thoroughly and recommend the most cost-effective repair, focusing on what you actually need.
Heat Pump Installation
Heat pumps are quickly becoming a favourite option for Ajax homeowners who want energy-efficient heating and cooling in one system. Walchuk Heating & Cooling designs and installs heat pump systems that are matched to your home, your budget, and Durham Region’s real winter and summer conditions. We focus on comfort, efficiency, and long-term reliability, so your new system genuinely feels like an upgrade.
● In-home assessments and proper sizing: We visit your home to review layout, insulation, existing equipment, and electrical capacity, then recommend the right heat pump size and configuration so it’s neither undersized nor oversized.
● Air-source heat pump installations: We install modern air-source heat pumps that provide both heating and cooling, integrating them cleanly with your existing ductwork and controls where possible.
● Hybrid heat pump + furnace systems: For colder-climate performance and backup peace of mind, we design hybrid systems where a heat pump handles most of the work and a high-efficiency gas furnace supports on the coldest days.
● Energy-efficient upgrades and replacements: We replace older, inefficient equipment with high-efficiency heat pump solutions, helping reduce energy use while improving comfort room-to-room.
● Guidance on rebates and long-term savings: We explain available rebates and incentives for eligible systems, talk through potential energy savings and payback, and help you decide if a heat pump is a good fit for your home.
Walchuk Heating & Cooling helps you decide if a heat pump is the right fit for your home and provides heat pump installation in Ajax that delivers dependable comfort, strong efficiency, and reliable performance year-round.

Can you help with grants and rebate paperwork for heat pumps and new systems?
Schedule a CallYes. As part of our Ajax HVAC services, we can walk you through available rebates and grant programs for heat pumps and other HVAC upgrades, and point you in the right direction to apply. Our team stays familiar with the main incentive programs in our area and can point out what you may qualify for based on your home and the equipment you’re installing.
When is it time to replace my furnace or AC instead of booking furnace or air conditioner repair in Ajax?
Schedule CallIf your furnace or AC is over 12–15 years old, breaking down more often, or driving up your energy bills, it may be cheaper in the long run to replace it instead of pouring more money into repairs. You might also notice it struggling to keep the house comfortable or making new noises and smells that were not there before. When we visit, we check the system, talk through what we find, and give you both options: what it costs to repair and what it would take to replace. You get a clear picture of the trade-offs so you can decide what makes the most sense for your home and budget.
What’s the warranty like on a new HVAC system?
Schedule a CallNew furnaces, air conditioners, and heat pumps come with a manufacturer's warranty on the equipment, and the details depend on the model you choose. When we quote a new system, including heat pump installation in Ajax, we walk you through what’s covered and for how long, so there are no surprises later. Our installs are done to manufacturer specs and Ontario code, so you get the full benefit of the warranty and a system that’s set up to last.
