Tempstar furnace troubleshooting is easy to do on Tempstar appliances. Tempstar designs all their appliances with ease and peace of mind as the highest priority. And all their products deliver the best in quality, energy efficiency and reliability, and each is 100% run tested.
If you have a Tempstar furnace but it’s giving you some trouble, try these troubleshooting steps to get it working smoothly again.
Issues can often begin when basic furnace maintenance hasn’t been practiced in a while. A great way to start is to change your filters. Dirty filters can do long-term damage if they are left unclean because the system becomes clogged. If you have a disposable filter then replace it with the proper size and if you have a permanent one, wash it with soap and water, rinse it thoroughly and let it dry all the way before putting it back.
Another reason it might not be heating could be an issue with the thermostat. Make sure you’ve set your thermostat correctly and that the adjustable calibration scale is set up right. If it’s set correctly it could be a software issue. This is one of the most commonly overlooked areas in furnace troubleshooting but is the easiest fix! If this does work, it’s possible the thermostat will need replacing.
Lastly, make sure the furnace is getting adequate power. If it isn’t receiving any, go to your circuit board and make sure the fuses aren’t cracked or blown. If it’s blown, replace it but otherwise resetting the circuit should do the trick.

I left a live chat message on their website that my air conditioning was not working. Within 1hr a representative called me to discuss my options.
The next day he came to the house to review my needs and give me a price for a new system. Price quoted was less than I expected and the installation was completed the following day. I found their salesman and the installers very knowledgeable and easy to deal with. All my questions were answered. Everything was properly explained in regards to what unit was needed and why, along with instruction where needed for use.
The installers made sure everything was working properly before they left.

This is to thank Twintech Heating and Cooling for their exceptional and timely service. Mitch, their technician was very courteous and generous with his time right from his first meeting with us. He not only took the time to check everything but also educated us on why we needed what he recommended. Greg and Mitch graciously accommodated us on our requested day and time for job to be done.

Our furnace was rattling, as soon as we put our air conditioner on this past week. We had researched looking for a company that was Registered with Better Business Bureau, and this company TwinTech, had A+ Rating. Scott, was immediately helpful via text/phone and sent his technician as soon as he was able...Mitchell/technician provided great professional service. Thank you TwinTech.

I contacted various companies when looking to install a new furnace and I found Twintech to be transparent with their communication and approach. They had options to suit my various requirements and the price vs quality was very good. The after installation communication was also very good and they answered all queries I had.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
