I had Enercare come in and tell me I needed a new furnace because I had a crack in my heat exchanger, tagged the furnace as unusable, they even showed me a picture on his phone. I requested quotes through HomeStars for a new furnace and Richard called me back. He was very thorough and honest. He asked how the crack was diagnosed, and after telling him he said that didn't seem right. I had him come in to give a second opinion for $200. I watched as he opened up the furnace, take pictures, look through the scope etc. No crack to be found. Enercare had shown me an old picture. Richard even fixed the humidifier that was installed incorrectly, gave me some helpful hints and tips, and removed the tag. Richard is a friendly and outgoing individual who saved me thousands with his honesty. I highly recommend CoreTemp for your furnace needs, thanks again Richard!" > Source: Chris (5.0, via HomeStars) > "I cant recommend Coretemp and Richard enough! When my furnace started blowing cold air on one of the coldest nights of the winter season, I was desperate. The first company I called sent a technician who couldnt figure out why the furnace stopped working. He managed to get it running temporarily but told me Id need a new furnace soon. Sure enough, a couple of days later, it stopped working again. I was ready to give up and buy a new furnace, trusting the first technicians advice. But something didnt sit right with me, so I searched online and found several posts advising against rushing into such a big purchase. Thats when I came across Coretemp on HomeStars. One review described a situation just like mine, and I decided to give them a call. Richard answered my call at 9:30 pm on a Friday night and was at my door early Saturday morning. He even apologized for not being earlier because I had overslept, not him me. He was ready to go at 6 am! it was a cold night for us and he was there early to help us. What truly impressed me was that Richard had done extensive research overnight, consulted his colleagues, and arrived prepared with potential replacement parts. His diagnosis was absolutely spot on. He found the issue, replaced the faulty part, and took the time to explain every detail about my furnace. Thanks to his expertise, my furnace has been working perfectly ever sinceeven during the coldest winter days. Richards professionalism, intelligence, and honesty set him apart. He genuinely cares about his customers, going above and beyond to provide excellent service. He even follows up periodically to make sure everything is running smoothly, which I really appreciate. When its time to replace my furnace or get a new AC, Ill definitely call Richard and Coretemp. Im so grateful for the care and dedication he showed to me and my family. Thank you, Richard, for going the extra mile!" > Source: Anonymous (5.0, via HomeStars) > "I contacted Richard as my furnace wasn't working properly and I needed a service call. It was determined that I should replace the furnace as it was old and parts were discontinued. Within 3 days Richard and Eric showed up and replaced my furnace.(I still had heat so wasn't an emergency) They were very professional and very tidy. They really know their stuff! I am very pleased with the workmanship and friendliness they showed. i would definitely recommend Core Temp for any service they provide." > Source: Anonymous (5.0, via HomeStars) ## Trades Electrician, Appliance Repair, Handyman, Hvac Contractors, Plumber ## See their work _Portfolio and gallery links this business publishes.

Electrical, gas and plumbing are licensed trades almost everywhere (for example ESA for electrical and TSSA for gas in Ontario), so check your provincial regulator that the contractor is certified for the work before you hire. - A construction lien is a real risk: in every province an unpaid subcontractor or supplier can register a lien against your home even if you already paid the main contractor. Hold back the statutory amount (commonly around 10%) and get signed lien waivers as you pay. - Confirm they cover your area and can actually come out in your timeframe before anything else. - Read recent reviews for reliability and turning up on time, not only the quality of the work. - Agree the call-out fee up front, and be wary of large upfront deposits for an emergency job. ## Contact - Phone: (416) 520-0574 - Website: http://www.coretemp.ca --- Source: MyTrustedTraders, https://ca.mytrustedtraders.com/traders/coretemp-heating-and-air Real public evidence only: every figure traces to its named source.
