Wow. So thankful I called this company. They are wonderful.

I called them on Tuesday to fix my HVAC unit as the heating unit wasn’t working. They ordered the parts which came in on Thursday, and by Thursday evening my house was nice and toasty.

SIMS is professional, great pricing, speedy, quality work, and just a great experience overall. I can’t believe how quick they were able to come out and work on our unit. They kept me posted with pricing, called me right away and showed up when they told me they would.

Thank you so much!!!!

The service I received from SIMS Heating & Air was ABSOLUTELY INCREDIBLE. We called them when we suspected our 20-year-old air conditioner was ready to be replaced.

I would HIGHLY RECOMMEND this company to my friends and family and will absolutely call on them in the future for all of my heating and air conditioning needs.

Summer has now ended and I wanted to service my air conditioner and check on any heating issues I might have in the upcoming cold months.  Dan from Sims Heating and Air came in and inspected everything thoroughly!

All for a fantastic price!  You will get an honest service with Dan and his crew and will make sure the headaches of air conditioning will be erased.  I will only use Sims Heating and Air from now on!  Perfect service!  Thank you!
