Ashton Heating & Cooling BBB Business Review


Ashton Heating & Cooling
Based on 247 reviews
review us on
If I could give these guys 6 stars I would. The freestanding gas fireplace, in the home that is new to us was not working properly, despite the promise of the home inspection. I reached out to Mary in the office a couple of days ago - she gave us a quote for cleaning (and some reassuring words) and we booked a time for our service. Mike, the tech, arrived at the promised time today - he was excellent (even gave our 2 year old grandson a "tour" of his tool kit). There was a little more involved than a cleaning - but we are so happy and enjoyed the fireplace this evening. Kudos to Mike and the team at Ashton‼️Update - just had Cory here to do our annual A/C service. On time, efficient, courteous, great customer service - what can I say; a premier organization! Thanks so much. 👍👍
Response from the owner: Thank you Peter! We truly appreciate your kind words and we are glad we could get you up and running! I told Mike to bring you some special HVAC stickers for your grandson next time 🙂 Call or text us anytime-Bill Ashton- 905-240-6055
Highly recommend Ashton Heating and Cooling.
Response from the owner: Thank you Linda! We appreciate you taking the time to leave us this review and we're glad your experience was deserving of five stars. We hope you have a safe and warm winter! All the best, call or text us any time- Bill Ashton 905-240-6055
Ashton Heating & Cooling responded quickly to my request for service. The technician was friendly and professional. The installation was completed in a timely manner and the work site was left clean.Thank you for your excellent customer service.
Friendly service and thorough.
Josh came to clean our ducts after having a bunch of home renovations. He was very pleasant to have in our home. He was respectful of our home, friendly and transparent. I would definitely recommend this company and will use again in the future.
We had our air conditioning unit cleaned and inspected yesterday. The technician was friendly and educated us about our air conditioning unit. We’ve been very impressed with this company as last fall we had an Ashton tech come take a look at our furnace for a second opinion after another company had told us we needed to get a new furnace. Turns out our furnace is fine. I have since removed my monthly service agreement for the other company and will only trust Ashton Heating & Cooling for our A/C and furnace needs.
I recently had a fantastic experience with Ashton heating and cooling. Their technician (Corey) was incredibly knowledgeable and provided excellent service from start to finish. The entire process was smooth and professional.Additionally, their website is very cute and user-friendly, making it easy to find the information I needed and get in touch with them. I highly recommend Ashton heating and cooling for anyone in need of air conditioning services.They truly offer excellent service with skilled professionals.
On time, courteous,knowledgable....Great Communication
This will be the 2nd time I've personally hired Ashton Heating and Cooling foe HVACServices. And yet again they've exceeded my expectations. They're prices are fair and the team is knowledgeable and courteous. They cleaned up the space as if they were never here.I'd totally recommend the and do often.

We had a gas line installed for our bbq. I got a quote via text from the owner. we booked a time that worked for us and even with the covid-19 issues he accommodated in every way. I will be calling in the future as my 15 year old home needs a furnace and water heater.Update!Moved houses, needed a new BBQ hook up, they came out within 24 hours. Will be booking a new humidifier and water tank later this summer!

Ashton heating and cooling have always been prompt, efficient and friendly. I recommend them highly
I had a Gas-line for a stove and an “in-duct smoke detector” installed, the price was reasonable. The job was done with in a reasonable time frame. Overall I am well pleased.
I have been a home owner in Oshawa since 1980 and Ashton's is simply the best and most reliable HVAC service company I've dealt with.

Response from the owner: Hi Mandy, we are so glad we were able to extend the life of your hot water tank as long as possible. You should be good for a bit now 🙂 Do not hesitate to reach out in the future, Bill Ashton 905-240-6055

Bill and his team did a tremendous job at my very old house updating all the ductwork.They were professional, clean, finished the job in the expected timeframe and the price was exactly as quoted to me.5 stars, would recommend to anyone looking for an honest HVAC company.
Great service . Cory explained everything in detail and answered all my questions. Highly recommend.
Great company. They always show up on time, are professional and don't leave a mess. We always use them for our heating/cooling needs and send as many people to them as I can.
Ashton Heating and Cooling has installed a heat pump and a whole house dehumidifier in our home. The quality of the installations has been excellent. The installers are very professional and always arrive on the agreed upon time. This is a great company to deal with.
I can't say enough about how pleased I am with the service I received. The crew, Bill, Cory and Dylan did an excellent job removing and replacing my old furnace and piping. They were very professional and diligent in their work, ensuring everything was functional prior to leaving. Thank you for expeding so quickly as well.
Response from the owner: Thank you for the kind words Olga, we really appreciate your positive feedback. I will make sure to share your kind words with the team. Do not hesitate to reach out if ever in need, Bill Ashton 905-240-6055
I had what turned out to be a tricky furnace issue, and was so pleased when Ashton Heating and Cooling resolved it. The professional and knowledgeable technician provided excellent service. I've been a customer for many years and wouldn't even consider switching! Thank you!
Response from the owner: Thank you Liz! We appreciate the opportunity to be your home comfort provider.Please feel free call or text us anytime should you need further assistance,Bill Ashton- Ashton Heating- 905-240-6055.
Cory was pleasant, careful and efficient. The text for appointment reminders and arrival estimates were helpful. The only negative is the cost for servicing an electric furnace is too much.
We have been dedicated clients of Bill Ashton and his amazing crew for nearly 2 decades, along with family and friends to whom we have recommended their services over the years. On this recent occasion, having had a starling find its way into our gas fire through the builder's aging vent, it was a pleasure to work with Cory to fix the problem against future invasions. His patience and pleasant nature made the whole exercise far less stressful than might otherwise have been the case. 5 stars once again (as always!!)
Response from the owner: As always Rusty, it is a pleasure working with you and your family. Thank you, Bill Ashton 905-240-6055
Boiler breakdown with same day service and next day new installation. Great value.
Great service. Technician Cory was knowledgable, professional and quick. Recommended.
Incredible, fast, knowledgeable service. I will definitely call again when we are working on our fireplace.
Cory was extremely knowledgeable and helpful when we were having challenges with our furnace, he also advised me of some ways we could improve air circulation in our house and increase the longevity of our furnace. I got a text to let me know what time he would arrive and got a full report of the maintenance he performed. We'll definitely contact Ashton Heating and Cooling next year for our next servicing!
Response from the owner: Hi Samantha, thank you for lovely review and we will make sure to share your kind words with Cory. We look forward to working with you again. Bill Ashton 905-240-6055
Had Ashton come to check on why the furnace didn't seem to kick on earlier today. Everything has been checked and is working. And as always, they took the time to explain what I should be looking for should it happen again. Efficient and professional as always. Thank you Cory!
Response from the owner: Thank you Cathie! That really means so much to us to hear. We truly appreciate you being a customer and wanted to say a big THANKS for coming to leave us this nice review. All the best, call or text us any time- Bill Ashton 905-240-6055
Great service. I would use them time and time again.
My furnace was turning on and off when it felt like it. When Cory came he took his time to explain what the problem was and fixed it without any issue! We appreciate his help and will definitely call him again if needed! Thank you!Kosta Skarlatakis

In houses with forced air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. But in typical houses, about 25-40% of the air that moves through the duct system is lost due to leaks, holes and poorly connected ducts. The result is higher utility bills and difficulty keeping the house comfortable no matter how the thermostat is set. 

We’re proud to offer AEROSEAL- A revolutionary duct-sealing service to end cold rooms, and poor appliance efficiency forever.

Pricing is split into two parts, as not all homes will end up benefiting from a full system seal. 

Pricing Starts at $899 +HST for your initial inspection, which includes a whole home duct cleaning. While your system is sealed off and freshly clean,  Our special computer will run a detailed  report outlining the levels of leakage your duct system is experiencing.  

If the report finds that  Aeroseal would be a great solution to your leaks, we can proceed with the sealing process which starts at  $1300+HST.

Looking to get Aeroseal performed? We provide the Aeroseal Service in Courtice, Bowmanville, Whitby and Beyond.
