Coretemp Heating and Air reviews (664)

These guys are real pros - Richard, the owner, came out personally and walked me through the whole project, removing and replacing my old furnace, installing new furnace, and humidifier - we were so impressed we bought a central air unit (our first one!) from him also. As soon as the job was completed, and I walked inside i could immediately feel the difference with the humidifier and air flow - great , great job and highly recommend them - sincere and honsest guys.

Richard from coretemp was fantastic at helping me over the tele, and at the end cost me no money. Richard took the time to walk me through and diagnose a problem that might otherwise required a service call. I fixed it myself over the tele and my family is warm again!Good Karma Richard, and thank you!!

I had a hot water tank that I paid rent to Direct Energy for 30 yrs., It ruptured. Direct Energy said it would be 3 to 4 weeks before they could replace my tank. I then hired another company to put in a Rinnai tankless. They have since gone out of business and sold their business to Atlas. My tankless stopped working after 2 yrs and Atlas would not fix it. I luckly found Richard with CoreTemp who came the same day I called. He showed me the problem and why - incorrect installation by someone who did not know how to install. Richard put in a replacement while he took my Rinnai and fixed it. Rick then brought back my tank within a week and installed it to the building code. It works very well. I think Rinnai should know that this is installer is knowledgeable, professional and reliable. I trust CoreTemp and have recommended them to a few people.

Richard is great!! He responds almost immediately if I call and always comes quickly!! I respect his opinion and he never tries to up sell you!! My furnace broke down in the middle of the winter and he came very quickly!! He is fair and a very nice guy!!

Richard and his team provided excellent service. Installation in our fairly old Toronto house barely detached house was not easy and Richard tried to solve the challenges with great effort. CoreTemp readily answered calls and Richard came back to do a detailed review once the heating and water had been installed for a few weeks.

I had a new Ruud furnace and Rinnai water heater put in this past July. So far my wife and I are very happy with the hot water through the entire house. Even while the washer was running, someone taking a shower and dishes being washed. We are impressed with the heat coming from the furnace, especially how quiet the variable speed fan was when it is running. My son's room that was normally colder than the other bedrooms before feels alot warmer now. Also the few days we used the A/C in the summer we noticed how more even the temperature was. I guess that fan motor makes a big difference. On day of Richard arrived on time to start the installation and well equipped to do the job. Once they were finished working, the work area was throughly cleaned up and garbage taken away with them. I would strongly recommend using Coretemp because of their professional and courteous attitude.

I called Richard[Coretemp]as our furnace quit on us.Not only was Richard helpful over the phone...he came to our house within a couple of hours to take a look at the furnace.It needed to be replaced as there were cracks in it.Richard explained everything in great detail to us and being very pleased with his knowledge and professionalism we decided to get the Rinnai[tankless water heater] also.Richard and his workers did a great job with the installations.Richard has even called us a couple times to make sure everything was O.K.I would definately recommend Coretemp to anyone in need of a new furnace or even servicing their old furnace.Thanks Richard and the guys for a job very well done.

After 2 days of NOT receiving call backs from messages left with 4 other companys, Richard answered my first call and was out that day. We didn't like what he had to tell us, but after explaning what our options were, we understood what needed to be done. Richards service and professionalism were outstanding - I'm so glad none of the other 4 have called back (even 2 wks. later). Damn good job Richard !!!

This company was great. Not only did they show up when they said they were going to, they showed up a bit early! Richard was very open and honest about the things that needed to be done and was great at explaining what he was going to be doing. We were told from another company that we couldn't vent our furnace directly outside because we were below grade so we would have to do it through the chimney and that required alot more expense. I told Richard this and he asked me for a shovel and went outside to see how "below grade" we were and it was only a couple inches that he had to dig! The other company didn't even go outside! Needless to say we are very happy that we found this company and we will be using them from now on for anything that we need done with regards to heating and air.

While running diagnostics on our HVAC system, Richard from CoreTemp found an improperly and unsafely installed tankless water heater in our home (around 6 code violations that if remained undiscovered could have resulted in an explosion within our home)! We thought that the original company that installed our Rinnai tankless was a "reputable" company. Once he alerted us to the dangers of our poorly installed tankless, he immediately called the company that installed it, and advocated for us on our behalf. Thanks to him, he helped us get the problem corrected. He completely went that "extra mile" to make sure that it was "done right". He reminded us of Holmes on Homes and we feel he deserves his own show! He's very professional and his ethical character is refreshing to find in this business. Richard treats his clients as if they were his own family - he took it upon himself to ensure our safety. THANK YOU CORE TEMP! Words cannot express our gratitude.
