Second opinion HVAC system diagnostic/troubleshooting

In October 2023, I had a brand new HVAC system installed by one of the largest and best reviewed companies on Homestars that routinely appears on the first page under HVAC. This included a new Heat Pump/furnace, tankless water heater, and humidifier.

I couldn't say for certain, but the experience with the first company left me with the impression that I was oversold a product that didn't match my needs/property (century-old home, poor insulation), and that corners were cut with the installation due to a lack of experience/technical wherewithal. The marketing pitch that I was sold on for the heat pump failed to deliver, offering middling performance over the winter, and faulty function for the first hot spell in the summer.

This was unfortunately reinforced by the fact that the humidifier did not work during the winter that it was installed, and worse yet having the evaporator coil freeze up during the first hot spell when I ran the heat pump in cooling mode, leaving me cooking. I felt like I'd been taken advantage of, and was $20k in the hole as a result.

That's where Richard from Coretemp came in. I searched for a a certified Lennox Dealer in order to get a second opinion of the HVAC system's installation/operation. Richard, along with his colleague Eric, quickly identified numerous issues in the initial installation job, from minor points (incorrectly set up condensate drainage from tankless water heater/ furnace slope), to major (incorrectly paired TX valve, which is leading to the coil freezing up + low CFM from blower), as well as a minor gas leak!

Richard went above and beyond in coordinating with Lennox tech support to ensure that the optimal and correct solutions were found for my existing HVAC equipment. Every effort was made to get the equipment that I had already purchased working properly, as opposed to selling me new tech to replace the faulty system, which I was fully prepared to do.

It cannot be understated how amazing it has been to have made the acquaintance of Richard and Eric from Coretemp. They're truly the most honest, thorough, and considerate contractors I've ever had the pleasure to work with. The peace of mind in knowing, after my first problematic experience, that I've found the BEST HVAC contractor around (full stop), is honestly irreplaceable.

I would wholeheartedly recommend Coretemp Heating and Cooling without reservation to ANYONE in need of an HVAC professional. Thank you again Richard and Eric - you guys are the best!

HVAC - Furnace Air Conditioning

Coretemp (Richard) was one of three companies I had at my home to give me a quote on the replacement of my furnace and air conditioner. I found him the most professional of the three. He was professional, explained in detail what was required and provided pictures of previous jobs.
He and his team (Eric & Dave) arrived when promised and the job was completed professionally and within 5 hours. Everything was cleaned up and I would have no hesitation in recommending Coretemp to any of my friends or family.

Coretemp's Great Customer Service

Coretemp installed a new furnace & A/C in November 2023 after our 25 year old model was on it's last legs. Coretemp was competitive on price and very accommodating on an installation date. The furnace ran smooth and quiet all winter. When we turned the A/C on in May, it made a slight whining noise. Richard made sure our concerns were prioritized, coming on his own time to help diagnose the issue. It turns out the ductwork and lack of cold air returns are issue, as the A/C and blower are working just fine. Coretemp (Richard) puts the customer first and makes sure they are fully satisfied with the workmanship. Richard is professional and passionate about his work - the best customer service we have received in a long time.

Honest pros and great service

Years ago my first service call with Richard (the owner) on our AC he performed only the necessary repairs and it immediately impressed on me that I was dealing with an honest person. Recently we called him again when the AC finally died after 21 years of operation. We got a quality AC replacement and new thermostat installed by him and Eric. We recommended them as well to our neighbor who also got a new AC. They provided us with excellent service. He also inspected our existing rental water heater and pointed out the shortcuts the original installer did and that we should have the rental company rectify it. We are so lucky we found Richard and Eric from CoreTemp and can say we now have HVAC/Water Heater pros we can trust and recommend to others.

Diagnostic

Called Coretemp because of weird Carbon Dioxide readings on my thermostat. They came out right away. Erik was so thorough; he checked all equipment and and floor registers, took readings, and even checked my HRV. Richard, the owner, followed up about finding new pre-filters for my HRV which are discontinued and gave me a few options. Absolutely fantastic and honest customer service. I will definitely call them when my HVAC systems need to be replaced.

I've been a customer for over 10 years. Richard and Eric are top notch. Honest, knowledgeable, fair, down to earth. And you're dealing with the people that will do the work not someone that contracts out to others. I cannot recommend these guys enough!

CoreTemp Furnace Installation

Our 27-year-old furnace died during the February Family Day long weekend. After quickly researching the internet, we called 3 companies for estimates. Richard (owner of CoreTemp) actually answered the phone and was in our basement within 30 minutes. He was able to quickly get the furnace going (no charge) so we thankfully had heat again, but it was clear from his explanation (and age of furnace) that it was time for a new one. He provided us with a written quote and brochures and was able to do it without any of the pressure sales tactics/games so often used by other companies. Richard also called us a few times during the next 48 hours just to make sure the furnace was still providing heat. We also got quotes from two other companies, and after having to negotiate back and forth for hours for the exact same Lennox model and warranty that Richard offered, we decided to give our business to Richard (CoreTemp) based on price, in-depth knowledge, quick response time, and ability to explain everything clearly. The next day Richard and his assistant Erik arrived on time and professionally installed the furnace and left the area as clean as they found it. Richard took the time to explained how the new furnace worked and stressed that if we had any other questions to call him directly. I would rate the entire experience with CoreTemp as Outstanding. Richard owns this company and clearly takes pride in providing excellent customer service at a fair price. If all businesses were operated in this manner, what a wonderful world it would be with regard to home maintenance. I highly and confidently recommend CoreTemp to all family, friends, and neighbours.
