Quite simply, excellent service. From start to finish, Richard answered all my questions and made me feel at ease. Very professional and they always put the customer first. Would not hesitate to recommend CoreTemp to anyone. To Richard and Eric, thanks again for the quality work.

On time and on budget and even 2 years later there when we needed them. The furnace needed a part and Coretemp were there to fix it in no time the no question asked. They also did a very good job cleaning the furnace earlier in the year.

Richard and his team are amazing!!! highly recommend. Also they are available and actually answer the phone every time I call. Small Business Owner who know his stuff as he is also a qualified tech.

Reliable, fast and extremely professional. Richard came to our house within half hour, diagnosed the problem, got the part and fixed our furnace. Heat back !! SUPER communication and service ! On this cold Feb (after another contractor (a-z comfort air) checked and said big ?? problem, left us hang for 3 days no heat/communication) We called furnace manufacturer and CoreTemp 1 of 3 suggested licensed technicians - So recommend CoreTemp to friends/family no hesitation- thank you Richard for a job very well done.

It all started with a clunking sound and then a frosty morning—-inside the house ..... on a Friday!
Richard has a top notch team who responded quickly to my email, maintained contact, arrived on time, knowledgeably shared their assessment, ensured I had heat through the weekend and delivered a guarnteeed quote.
On Monday morning, they arrived bright and early, coordinated a retro exhaust fit with industry partners and installed a Lennox unit- (yes I checked- the unit has excellent ratings and dealers are known to have excellent follow up). Thank you for the bonus thermostat- WOW. Toasty now!
Richard leds a professional efficient team. They are kind and very considerate- tidy and neat. Would I sign on for year service with this CORETEMP? Absolutely, already did. What are you waiting for- call them.

I found this company through Homestars.com and I am very happy I did. Richard and his team were very friendly and a pleasure to deal with. They were able to review the issue the same day I called them and installed within two days of the first visit. The day of installation, they arrived early and were finished within hours. Installation was clean and professionally done, all ducts were sealed properly and they left no mess behind for me to deal with. A wonderful experience overall and I would definitely recommend them to anyone looking for furnace maintenance, repair or replacement!

Richard was the first of three companies to respond, so we liked that, right away. He accommodated greatly by coming on Saturday, which turned out to be a very hot weekend. He quickly and efficiently removed the a/c cowling and assessed the issue was with the capacitor---he showed me it was starting to swell and could burst. I like to understand how things work and why parts fail, and he was great at explaining everything. The cost for parts & labour was very fair and the work quickly finished. This is a guy who cares about his work and his clients.

On Novemeber 21, we noticed that the temperature in our house was dropping along with the temperature outside. After much tinkering with the help of the manual, we made a call to Coretemp about 9:00. Needless to say, we did not expect a call until the next morning. About 11:00 P. M. a call came from a sleepy Richard. They had found the message and called to see if the furnace could be fixed with some suggestions from Richard. After about twenty minutes of effort no luck. However Richard was able to determine what was wrong and which pieces to bring. The next morning, soon after 8:00 A. M., Richard arrived. The drive to Toronto took about an hour and an half in rush hour but Richard had the furnace up and running within a few minutes. We are very thankful for this excellent service.

I recently had a new furnace installed and was very pleased with the process. Richard quoted a fair price for the unit (compared to other quotes). He did the installation as we agreed and even took the time to explain a couple of other things to me regarding my humidifier and AC unit. I would not hesitate to use Core Temp again and would recommend them to anyone considering this type of work.

We had our furnace inspected by another company who decided he would RED TAG our furnace with an infant with a weakened immune system who was newly home home the hospital. Their offer: a single plug in space heater. Where to turn now? HOME STARS!

We found amazing reviews about CoreTemp and two other companies. We had all three inspect our home and provide quotes and specifications of service. Richard and his team were mid-range for quotes, but there was something about the push of customer service, the answers provided, the comfort around him and his team, and the positive feedback on Home Stars that we went with CoreTemp.

Installation was on point, professional and efficient. We couldn't beleive how accomodating he was, despite being the busy season. Richard in the first few months ensured everything worked well and checked in via email a few times (far beyond anything we expected)

In the last 3 years since, we've had issues with our thermostat. Instead of waiting on hold with Lennox (which could take forever) Richard sent himself or someone from his team on site to guide us and if the issue couldn't be resolved on site immediately, the thermostat was replaced.

We were so pleased with the professionalism and attention to customer service that we recommended CoreTemp to my in-laws who are just as pleased. We strongly recommend Richard and CoreTemp whether you need a new AC or Furnace or repair to your current ones.

Thank you, Richard, for AMAZING service.
