Recently had a new Heat Pump system replaced. Gage and his co-worker did a fantastic job. When I had called other companies prior they could not come out for a few weeks. Gage came the next day did a through evaluation and explained to me his evaluation in a way I could understand. The next week our system was installed. We are enjoying our new Bryant system. I will be recommending this company to others!

SubZero is thee and I do mean thee absolute best heating and cooling company I have ever used. The company sent two of the best technicians by the name of Shawn and Nate. They were courteous, honest, efficient and gave outstanding customer service. I shared my experience with my realtor and she said she would be recommending them to all her home buyers and sellers. I highly recommend this company. I assure you that you will not be disappointed. Request Shawn and Nate and tell them a very satisfied customer recommended them.

Joe was stellar in assisting me with my mini split. He offered a free consultation, came in time, did his research, and gave me different options to correct the problem. He walked me through program settings on my current device to eliminate the potential for system changes or new installations. I really appreciate the help without the pressure to commit to an agreement or pay for something I don't need. I will definitely be a return customer.

Seth and David were excellent! I can’t thank them enough for getting my heat working on a cold winter day. I called on a Saturday and my thermostat wasn’t working and I did not have heat. DJ said he could get me first thing Monday I was ever so grateful that he was able to fit me in within a couple hours !! My 78 year old mom is happy the house is warm too ! I recommend this company because they are all about service to their customer and we’re prompt and professional !! Call Seth and David !

Over the summer after 2 other companies checked my A/C unit I called Sub Zero and they were able to fix it but let me know that I would need to replace the unit n the near future. My furnace quit working yesterday and they came out within 2 hours and got it running again. They came the next morning and replaced both units for me. Hard to find company that will go above and beyond for you these days and I highly recommend Sub Zero!

A few weeks ago I was having trouble with hot air from my furnace. Being a relatively new homeowner I did a Google search and called dormar for an opinion. They were out and the guy suggested I needed a new furnace (I thought this was a little strange as the furnace was installed less than 6 years ago). Today I woke up and noticed it was a little colder and the same issue was occurring, going to the worst case scenario of needing a new furnace I decided to get a second opinion or getting multiple quotes to compare the replacement cost. I called Sub Zero and could not be more thrilled with their service, timeliness and how efficient they are. They were out within an hour. Ben the technician within 15 minutes located the problem to a pressure switch and fixed it on site. It takes a lot for me to write 5 star reviews but I will be switching to sub zero for all my heating and cooling needs. It’s great to see a company not sending sales men out or having the go to as a replacement system. Thank you guys again for getting the problem taken care of .

Brian and another man came and installed a new furnace at my mother in laws home. They had to do a lot of work including taking out a huge super old furnace! We were very happy with the service and are excited to have a new energy efficient furnace! Thank you for sending experienced, friendly and knowledgeable guys to install her furnace.

Ben M showed up exactly when he said he would. He listened to my concern and asked questions so he could get to the root cause of the issue. Ben was extremely professional and ensured that everything was in proper working condition before he left the house. Ben made sure that I understood what the problem was and what steps were taken to fix it. I will call Sub Zero with any future heating and AC needs and will definitely refer my friends.

Subzero has handled my repair needs for years. When my 20 year old AC gave out, I decided to replace the entire system. The AC never worked well due to the unit being undersized, and there was never enough airflow returning to the furnace. Chris figured out how to make the new system (higher efficiency) work as designed by adding more return air to the furnace. He figured it out whereas others merely proposed the easy way out in my opinion. I’m very happy with my new Daikin equipment! I would recommend Subzero without a second thought and will continue using them for all of my HVAC needs.

Contacted Sub Zero that same day they were out. Never used them before, but after my experience I would call the again for service. Josh was the tech that came out, he was polite and friendly very professional. Gave me some good tips. Was very pleased, thank you Josh and SubZero for your professional service.

I called Sub Zero in need of service on my central ac unit- was running low on refrigerant. I knew I had a small leak, but had put it off. Of course this issue reared its ugly head when Mother Nature decided to crank up the heat! I called around 10:45 am in the morning. The gentleman that answered said that they were very busy- completely understandable and expected. He put me on the schedule for the next morning, but said a tech would call if something opened up. Not even an hour later, their tech Gabe called and said could be there in 30 mins. I was ecstatic! Gabe and his crew of trainees showed up and got right to work. They sprayed off the coils on my outside unit, put in refrigerant and leak sealer, sealed up the service port and put new caps on the low and high side ports. Top notch professional service that cost much less than I had anticipated. I definitely recommend them and will use for all of my future hvac needs!

Josh just came by to diagnose my heating and cooling systems. He was very informative and professional giving me a reasonable quote. I called earlier in the week and they called me this morning to schedule a time convenient for me.

Had the BEST experience with Josh from Sub Zero Heating & Air Conditioning today! He was courteous, punctual, and his thoroughness cannot be matched. After an extremely poor experience with another local company Josh was a godsend. I would recommend SubZero and Josh to anyone for top-notch service. In the middle of COVID-19 and erratic early May weather our furnace (and with it the AC) would not turn on. My husband had pinpointed that we had an electrical issue with our over 15-year-old gas Carrier furnace as fuses kept blowing the second we started up the furnace. Within 24 hours of calling SubZero we had Josh at our door. **He wore a mask and used social-distancing precautions throughout the entire service period. Josh took extra time (about hour and a half) to make sure the system was working properly and after crossing off every potential problem pinpointed an extremely abnormal issue where an electrical wire above the basement unit was pinched/melting slowly due to it being stuck near a heating vent/metal ductwork. He quickly (in an hour) resolved the wiring issue along with another issue with our air vent. He kept us informed throughout the entire service period and pricing was extraordinarily reasonable. We will never call anyone else for HVAC service. Very impressed with Josh and SubZero Heating & Air Conditioning.
