Technician arrived at 8.am sharp,was very professional,seemed to be extremely knowledgeable and in my uneducated opinion was very thorough as well as leaving no mess or indication he was here.I listened to the amount of debri that was collected and there was no doubt that I required the service.I was very impressed with the entire experience

We recently had to replace our furnace after using it for 21 years. I reached out to Oliver Heating and spoke to Elise, who was fantastic and arranged for Steve to visit and evaluate our needs. The installation of the new furnace was done by the company to a high standard. During the process, their team of technicians worked diligently to ensure that everything was done correctly. We were impressed by their meticulousness and their willingness to go above and beyond to complete the installation, including cleaning up and removing all old equipment to our satisfaction.

Moreover, when looking for a company to handle such an important task, you want to be sure that you're dealing with a reputable business that won't take advantage of you and offer a fair price for their services. We can confirm that we found exactly that with Oliver Heating. Their commitment to providing excellent service and fair pricing was evident from the moment we contacted them. We felt confident in our decision to trust them with this significant investment and were not disappointed with the outcome. We highly recommend Oliver Heating to anyone looking for a reliable HVAC company.

TH Oliver helped me choose and install Aprilaire Model 400M (manual control) whole-house humidifier.
All of my questions were promptly answered, including technical questions about installing in the system with an UV light, which required contacting the manufacturer. The price was reasonable and installation was flawless - some manufacturer-provided components were replaced with better quality ones to give additional peace of mind and the emergency drain line was also installed.

After operating the humidifier for a few weeks I've decided to set the humidity level between "30" and "35" to minimize amount of condensation on windows (I unfortunately only have double-pane windows). I use the ecobee thermostat and wish it supported both an HRV and a humidifier without custom components. Automatic operation of the humidifier to make the level more comfortable when it's not too cold outside is the only improvement I want, but the manufacturer's own automatic control wasn't too convincing. TH Oliver advised to go with manual, less expensive control while smart thermostats catch up.

Thanks again TH Oliver Team!

We recently had a problem with our furnace and called TH Oliver. As always they responded, found the problem. They provided professional, courteous and efficient service as they always have. We have used this company for years for our Heating and cooling issues. They even installed a gas fireplace in our house for us. We highly recommend this family owned, local company.

Due to a failing 20 year old heater and twice-repaired air conditioner system, I was left in an HVAC bind for my home as the winter approached. Oliver Heating and Cooling was able to work with me within my schedule and also helped make things right when complications arose. They helped us get all the ducts cleaned, and supplied and retrofitted a new Daikin high-efficiency stage 2 furnace and Daikin 2 Ton AC unit (12 year warranty on parts and labour!) -- it feels as if it moves air faster, warmer, and all so much more quieter by comparison! The cleaning and install teams were professional, expertly knew exactly what they needed to do and took care of everything. They even took the time to explain things and share their experiences. Thank you to Elise and team for continuing to keep me and family safe and comfortably hot and cool!

Highly recommended and if speed-dial was still a thing, it would be Oliver's Heating & Cooling!

Oliver Heating and Cooling have been reliable and trustworthy over the 15 years of service to my home. Always dependable and helpful.

Friendly efficient service! On time and well priced, I took over the warranty service from previous home
Owner and I am confident things are running smoothly with my furnace.

As we never had our ducts cleaned before, it was time as we were getting a strong burning smell from our ducts.
The Oliver Heating & Cooling technician explain the whole procedure prior to starting the work and let me know all the steps he would be performing to complete the cleaning.
Needless to say the work was performed quickly and thoroughly and now we have no burning smell at all.
I highly recommend Oliver Heating and Cooling for this service.

Elise, Stephen and the whole team are so incredibly nice. They were so helpful when my furnace fan was acting up and were able to help me quickly so that we didn't melt in the summer heat.
We love our new furnace and will never look for another HVAC company again!

Great company to work with. Very professional, helpful and timely with my fireplace installation. Thank you!
