Coretemp Heating and Air

13 year old furnace needed a new exhaust fan. Everyone priced a repair so high that replacing the furnace looked like the only choice.

I called Richard at 5pm and he said he could come the next morning. He arrived at 9am with the part which he fitted in 45 minutes.

My old furnace has been keeping us warm ever since. Thanks Richard, I know who to call when it does come time to replace it.

We had our furnace and air conditioning systems replaced by CoreTemp in June and were extremely satisfied with the quality of their products and services. After talking to Richard for a quote, we knew he would be the one we can count on to get the job done right. He was honest, polite and highly knowledgeable. A couple of days ago, a hugh storm plus extreme weather plugged up one of the ventilation pipes and prevented the furnace from generating proper heat . Due to the terrible road conditons, it would have taken Richard hours to get to our place to fix the problem. However he was able to walk us through the process of trouble shooting over the phone and got our furnace up and running again within minutes. We truly admire his expertise and quality of services and would highly recommend his company. We are so glad we chose CoreTemp knowing that any future calls will surely be taken cared of promptly and efficiently.

My wife and I interviewed 4 heating companies and chose Coretemp to install a high efficiency furnace (Lennox SLP98UH070XV36B) and a tankless water heater (Rinnai RU98i). We are extremely glad we did as we are very satisfied with both products. The installation of both took place last April. At that time we were extremely impressed with the service and workmanship of Coretemp. We are writing this review now, as the new furnace was not used much last spring. We wanted to give Richard and his staff a truthful and superlative review which is only possible after having run the furnace for a couple of months in some really cold weather.

Our house is 100 years old. It has three stories plus a basement. Anyone living in such a house knows how hard it is to get even heat distribution throughout the home and how hot the third floor can be when trying to heat the other floors appropriately. We don’t have this problem anymore. Richard suggested an upgrade from our mid-efficiency furnace to a high-efficiency one with variable-capacity. He sized the new unit correctly – the older one was oversized. Whereas the old furnace noisily and continuously cycled on/off thus blowing huge and noticeable gusts out the vents, the Lennox is extremely quiet and warms our rooms without gale force. We don’t have a problem with the third floor. Our house is amazingly comfortable. Concerning the installation of the Lennox, Richard is second to none. Richard made very little mess in the basement despite the finished ceiling – no mean feat as he ran 15 ft of air pipes to an outside wall and snaked condensate piping 20 ft to another utility room which had a drain. Lastly, we appreciated that Coretemp submitted the Ontario energy rebate forms on our behalf.

Concerning the Rinnai which replaced a traditional hot water tank, we couldn’t be more satisfied. Richard assured us that the unit would provide ample water for our needs and that it would be very quiet (a consideration as it is beside a basement bedroom). This is so on both counts. He sized it correctly and hot water is more plentiful and continuous, and actually much quicker to obtain on the second floor than with the conventional tank. My wife was a bit dubious about going tankless but she is a believer now. Richard hired Tom at TMAC Heating and Air Conditioning to run the new gas line to the Rinnai. Again, another professional who is expert at his job. Tom ran the line outside the house, re-jigging the gas unit/meter to fit the pipe. The unit with additional pipe as well as the pipe running along the house in a mutual laneway are extremely unobtrusive and neat looking. We would hire Tom again if the need arose.

It was a pleasure dealing with Coretemp, a family company which delivers what it promises and then some. The job was done when scheduled, on time, and at the quoted price. Richard himself did the installation with 2 assistants who were hard-working and polite and clearly respected and liked their employer. Any mess was cleaned up at the end of each day of our two day install. Richard could be reached by cell before and after the install to answer any questions or concerns. His wife, Janice, was a pleasure to deal with by email as she manages the office. We highly recommend Coretemp and wish everyone connected with it continued success.

Following an electrical rewiring of our home, our AC would go on when turned on our furnace. Our electricians insisted that it was a programming issue and NOT a wiring mistake on their part. Instead of contacting the HVAC company they suggested, we opted for Richard and CoreTemp due to our previous experience.

Keeping consistent, Richard was timely and personable. He quickly diagnosed our situation to in fact be a wiring issue, and was able to not only fix the issue - he also upgraded our stat AT NO CHARGE with a sample he had kicking around in his truck.

Richard will continue to be our #1 option when it comes to ANY of our AC / HVAC needs. Highly recommended without question to anyone.

My furnace stopped working, called Core Temp for their 24/7 service, but Richard was on a job and couldn't accommodate us. He recommended we get some in the morning and closer in my area to avoid extra charges if he comes in a long way.
However he stayed on the phone asking about the problem, walking me through troubleshooting steps till it actually worked again. He spent about 20 min helping me on the phone without expecting any return.
Very helpful, very honest.

In short - this is the second time we have purchased a Lennox furnace through Richard and it was another great experience.
I highly recommend CoreTemp.
For more detail: We told Richard that we needed a high efficiency furnace in our last house because we were going to be there forever. That was not the case because with two kids we ended up needing more space and moved Oakville. The new house was 30 years old and the furnace was OK. I had asked Richard to inspect it and make sure it was safe. He checked everything and said we should not have any issues. He noticed however that the venting was incorrect and recommended someone to fix the ductwork. His colleague arrived within a few days, confirmed that there was just some minor duct repairs needed and provided an estimate. He returned that week to start the work. To our dismay - he found that the venting was not to code once opened up and required about a $800 to re-route. Together with Richard we decided to invest the money in a new high efficiency Lennox furnace and tankless water heater (through another great company AlphaAire). His guidance and support was great. He also checked in with us during the installation to make sure everything was being done well in coordination with the water heater. Richard is sincere, helpful, considerate and it is a pleasure working him and Janice (who made sure we took advantage of any Lennox/Government rebates for a high efficiency furnace)

If you are searching for someone to service your furnace/AC, or do a new install, let me save you some time... Call Richard at Coretemp. I got my new. Lennox installed today, and I am thrilled with his excellent work, honesty, and fair price. Richard gives you that personal touch that is sooo missing from the big companies. More importantly, if anything were to go wrong, I know I can pick up the phone and he will be there to help.
HIGHLY recommended.

I just had the most remarkable furnace service call experience! The owner, Richard Payer and one of his team (I'm so sorry I forgot your name) were amazing. I had had a service call with another local HVAC company about 3 weeks ago and was appalled at the poor service and in particular that the technician tried to charge me more than the heavily advertised price of a service call. The furnace didn't seem to be working right after that service call with the other company, so I wanted a second opinion. I'd seen the Core Temp van around Oakville, read the positive reviews on Homestars and called for an appointment. Richard answered the call himself, and was able to come by a few hours later since he was in the neighbourhood. To say I was stunned is an understatement! Richard is a very knowledgeable and competent expert who immediately diagnosed the problem with the furnace, gave me an honest opinion about the potential need for a new furnace and provided an explanation of everything as he went along. Needless to say, I’ll be getting my new furnace installed by Core Temp as well as a new air conditioner in the spring. I cannot say enough about the positive experience. The price range quoted for a new furnace and air conditioner is competitive IMHO and I am happy to pay a bit more for a positive experience with someone who is trustworthy and reliable. And they were very pleasant too; nice guys DO finish first. I’ve never been so pleased; highly recommend Core Temp.

I am more than pleased with the service we received from Richard and Erik at CoreTemp.
After removing an old deck from our home we wanted to replace our poorly maintained, poorly placed central AC unit.
Richard was very honest and knowledgeable. Although we were ready to replace the unit Richard let us know that the unit had some life left in it and if we just wanted to move the unit it would not cost us as much. We chose to go ahead with a replacement.
As we were having some landscaping done the hole for the lines needed to be moved to a higher position on the wall. Richard and Erik took care to not damage our double bricked wall and offered to fill the old hole for us.
They also installed a humidifier and whilst doing so came across a few minor issues that the previous hvac company missed when they were here to clean our ducts and service our furnace just a few weeks earlier. These little 'surprises' did not cost us anything extra.
CoreTemp was prompt, professional, through, incredibly knowledgeable and friendly. I was able to ask questions (many questions!) and was never made to feel dumb or like I was being a bother.
After they were done everything was put back and tidied as if they had never been here.

Thanks guys!

Our home purchase in 2011 was equipped with the original furnace installed, 20+ years ago. A replacement was on the "To Do" list and after reviewing furnace brands and HomeStars listed contractors, I contacted CoreTemp regarding a furnace replacement. Richard was out of town attending a conference. However, that evening, Richard returned my call while on conference in the US and inquired about our original install! How many contractors do that? We talked Furnaces for about 20 minutes. He offered an estimate on replacement and arranged an appointment to inspect the furnace on his return. I was impressed. The following week, Richard arrived on time and had a look at our furnace. He said he knew this model of furnace well and from past experience, he suspected that we probably had cracks starting on the back side of the heat exchanger and suggested replacement as quoted. I had another quote arranged but assured Richard that I would be in touch.
In the mean time as luck would have it, the following week we had a "no heat" situation and called Reliance for the repair. I had their Protection Plan and the service was included. The tech replaced the high limit switch and installed a jumper that was not reinstalled during a previous service call. Concerned about Richard's thoughts on the heat exchanger, I had the Reliance tech perform a carbon monoxide test. He did not diagnose any issues. I hesitated. Did I really need to replace this furnace? Richard's concern about the heat exchanger seemed genuine. We decided to replace the furnace as planned and selected CoreTemp for the install.
During the install, Richard called me to the basement. He had the old furnace removed and wanted to point out not one, but THREE cracks on the exchanger, exactly where he suspected they would be! Having a family of his own, Richard indicated that we had made a wise decision on the replacement, despite the results of an inadequate test performed by Reliance.
The work performed by Richard and crew was clean and professional and he has impressed me with his courteous, almost "small town" like, customer service. I look forward to having them back for annual maintenance because I'm confident that when they inspect, it truly will be "peace of mind" protection.
