Maximize Your Home's Comfort: Rely on Vanguard's 37-year Service Record

In business since 1979 and locally owned and operated, Vanguard Heating & Air Conditioning, Inc. provides service for all brands of heating and air conditioning systems. Being comfortable in one's home shouldn't be a problem, and it isn't when you let the experts at Vanguard Heating & Air Conditioning, Inc. install a customized heating or air conditioning system that's right for you. Vanguard Heating & Air Conditioning, Inc. takes pride in the fact that the installers and certified technicians are their employees and not subcontractors.

Some heating and air conditioning businesses open and close their doors faster than you can adjust the temperature on your thermostat. At Vanguard Heating & Air Conditioning, Inc., we've been in business for over 30 years, and our owner-operator has been in the industry for over 50 years. Our longevity is a testament to our superior products and customer service.

What Our Clients Say

We have been a customer for many years and always very satisfied! Thank you. – Mrs. Shalzi

“Overall, we are very pleased. I feel that that this installation presented some challenges, and your men were able to meet them. Initially, I thought your price was a lot higher. But when the men were here, I saw how many hours they spent modifying our old set up to meet the new system. I now realize that another contractor may have had a lower estimate, but would surely have had many extras.” – Mrs. Willy

“Reliable and dependable” – MJ


We care about our community and we believe in giving back.
