Air Conditioner Service & Repair

Ottawa’s Most Trusted Air Conditioning Service, Repair & Maintenance

Ottawa summers can be unbearably hot. We need to be able to rely on our air conditioners to keep us cool and comfortable. But just owning an air conditioner isn’t a guarantee that your home will stay cool all summer. Unfortunately, breakdowns happen and repairs are needed.

To ensure your comfort and safety throughout the year, it’s crucial that you schedule routine air conditioner maintenance. Whenever there’s an issue, always have it serviced and repaired as soon as possible.



Emergency Air Conditioner Repair

Air conditioners and HVAC systems don’t just break down between 9 AM and 5 PM, Monday to Friday. That’s why we offer HVAC services until 8 PM. And when you phone us in the case of an AC emergency, a real person will answer your call.



Air Conditioner Maintenance

Air conditioner maintenance is a necessary part of keeping your air conditioner healthy, efficient, and functional. It’s recommended that your air conditioner is serviced once a year. Regular preventive maintenance can elongate the life of your air conditioner, and it’ll save you time and money.

I changed the rate because the reaction from site office is extremely satisfy. I have no heat during the weekend and complained. I got a respond very quickly from their site office and find out the... reason of no respond. Then a new appoint was scheduled right way! Also a report has been filed towards this issue and I believe communication will be taken to improve future services. I really like this manner! Thank you.//I have no heat on the coldest day this winter. I called for service at 10:28am, and the office lady said someone will reach me ASAP. I called at 17:26pm again because NO ONE called me the whole day. And I was told there is a long list so THEY DON'T CARE! I HAVE TO WAIT! And this is a same problem happened second time in two years. Do not recommend.read more

I had an extremely positive experience with Team Harding from beginning to end. I had them install a Sterling Model GG 45,000 BTU Natural Gas Garage Heater with a Nest Learning Thermostat in my... double garage (Man-Cave).The sales rep, Brian was professional, friendly, he wasn’t pushy at all and he came under budget. Kirsten constantly kept me up to date on the installer’s scheduling and was a true professional. The installers came on time, did a tremendous job with the installation and they even cleaned up afterwards. Absolute Rock Stars!Again, thank you so very much to everyone that worked on this project for me.I highly recommend using Team Harding for your home projects.read more

Harding Heating & Air Conditioning were excellent. We had an issue with our furnace fan and I spoke to Natasha Wright (Service Coordinator) who first tried to troubleshoot the problem with me to... save costs, etc. Once that didn't work, a technician, Marc Gagon, attended. He quickly diagnosed the problem (faulty control board), but didn't stop there. He investigated the source - water under the AC coils. Further, he went outside to ensure the A/C unit was working properly. Marc Gagon is very professional, competent and took the time to explain things. He is a asset to Harding Heating & Air Conditioning, along with Natasha Wright. I highly recommend this company for your heating and a/c needs. Shawnread more

We have a 28 year old air-source heat pump that needed some TLC.Harding sent their tech out to diagnose, and provide options and pricing. Very reasonable.Exterior unit needed a new fan motor.... Within a few days an installer came and installed new motor, but made a slight error, and it was rotating the wrong way. Quick call had it corrected. Further found our defrost board was faulty. Harding provided quote upfront for a replacement aftermarket board. Kept in contact as to timeline and expected deliver and installation date.Tech came on-site as promised, did the install, and stayed to make sure unit was cycling properly. Billed for the quoted amount.Harding delivers what's promised, when promised, at quoted price. And has staff who know what they're looking at.Hard to ask for more from an HVAC service provider.read more

Very professional amazing staff. We had a technician come to see our old air conditioner which was beyond repair (we figured it would be). Next they had a staff member come to our house to look at... our furnaces and give recommendations for new air conditioners, he was very thorough and explained all our options in detail. Finally they came to disconnect the old air conditioner to take away for us and install the new air conditioners. The technicians were on time, very polite, did an amazing job and cleaned up after themselves above and beyond what I expected. Their prices were very reasonable and the after care packages that are included give us peace of mind for the future. I would highly recommend this company to anyone. Thank you Harding!read more

Brian was able to come by within a couple of hours and give us a fair quote, found a tank and coordinated the... install the next day (black vent pipe had to be replaced due to the code changing the colour to white).

Service is always great and with slight occasional follow-ups needed on the customer service calls, but the customer service and service people are great. They arrived promptly and easily fixed the... furnace issue we had as per scheduled. The defective part had to be ordered, but took only a day plus, and it was installed and working the next day, so now the house is warm again. Great service, that's why we've been with this service company since nearly 17 years. Highly recommend this furnace servicing company.read more

AC Troubleshooting Checklist



Inside the Home

Make sure the thermostat is turned to cool.
Check to see if you need new batteries in the thermostat. If batteries are older than 1 year old, they should be replaced.
Is the furnace switch turned on? (It looks like a light switch, and is located in the basement usually higher on the wall near the basement stairs or door to the furnace room).
Check the furnace filter- if your filter is more than one month old you should replace and/or clean it.
Is the furnace fan running with the HRV switched off and the thermostat fan set to ‘auto’? This tells us if the thermostat is calling for A/C if the fan is running.
Is the breaker in the breaker panel turned on? Normally it is a double breaker marked A/C.
Is there water leaking from the furnace? If ye, it is probably frozen- turn off for 24 hours.
Is there ice on the pipes or ductwork in the basement? If so, the unit must be thawed 24-48 hours before booking a service call. Readings will not be right if the unit is frozen and we will not be able to properly diagnose.
Is your equipment an Enercare rental? You will have to contact the rental company for service.



Outside the Home

Is the A/C cover removed from the unit?
Is the disconnect box turned on? It is a grey box with a plug/handle that is on the outside wall beside the unit.
Is there ice on the outside of the unit or pipes? If so, the unit must be thawed 24-48 hours before booking. Readings will not be right if the unit is frozen and we will not be able to properly diagnose.
Are the fins on the unit dirty or clogged? If so, disconnect the high voltage power for the A/C in the panel, then rinse with the water hose (do not use a pressure washer).
It must be over 18C outside so we can diagnose your unit properly.

Three Reasons to Schedule Annual Air Conditioner Maintenance

There are several reasons why you need to schedule annual preventative maintenance for your AC. The top three reasons are:

Increased Efficiency

A well-maintained air conditioner is an efficient air conditioner. By scheduling annual preventative maintenance, you’re ensuring that your air conditioner runs as efficiently as possible. This means you’ll have lower energy bills each month.

Improved Reliability

When you schedule annual preventative maintenance for your air conditioner, you can be confident that you won’t have to worry about a sudden breakdown or disrepair that could cost you more money in emergency repairs. When you keep your air conditioner well maintained, you avoid the possibility of future breakdowns.

Increased Home Comfort

A well-maintained air conditioner makes a difference in home comfort and air quality. Annual preventative maintenance means expert technicians clean your AC thoroughly so the air you breathe in your home is as fresh as possible. Plus, a well-maintained AC provides more even and more comfortable cooling.

Signs You Need AC Repair

Nobody wants to see that their air conditioner is in disrepair or on the brink of a breakdown. However, it’s important to keep an eye out for early signs that your AC needs repairs. The sooner you get it fixed, the easier and cheaper it’ll be.

Signs that you may need AC repair include:

Strange noises or smells
Uneven cooling
Increase in energy costs and consumption
Warm air coming from register
No air coming from register
Refrigerant leaks

Save Money with an AC Protection Plan

You can save money on AC maintenance, repair, and replacement costs by investing in a yearly Team Harding Protection Plan. We offer three unique plans with different levels of protection and discounts so you can choose the right protection plan for your home and your budget.
