Incredible experience! Fair prices with excellent service by honest people!!
These guys are lifesavers! Had a unit go out at my business and my usual HVAC company, who I have a service agreement with, came out to inspect and quoted me 3x what these guys quoted. They also said that it wouldn't solve the problem and I would need to replace the entire unit. These guys came out and within a couple of hours, assessed the situation and got me up and running for 1/3 the cost. They also gave me information on my system and told me they didn't envision a full replacement needed any time soon. Think I may be switching providers!

STOP!!!LOOK NO FURTHER! This company will get you right you hear me! They are the truth! I brought a house last year with A/C. Summer time came and the air wasn't working right at all. Call my home warranty company who came out several times but my house never did cool off. Finally after coming out again the warranty guys say my unit is too small for my size house and that's a pre existing problem. We suffered all summer because I couldn't afford to replace the unit at that time. Called Sub Zero they came out and said my unit was over charged. Fixed me up and now we are sitting in the north pole baby! You feel that heat? Nopeeee! Nothing but BURRRRR!!! Call this company. They could have lied and cheated me but they were honest and fast. They are the truth!!!!
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.

Dude who came by was efficient and quick.

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!
Matthew Herring

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 .

Honestly this is the only heating and cooling company I’ll ever use. Their service is unmatched and they have the best and friendliest technicians. Just the best company you could ask for. Thank you again guys for your continued help and service!

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.
