What areas do you serve?

Are your technicians licensed and insured?

That's a smart question to think about. At Sun Tech Air Conditioning, you can rest assured. Our lead technician has over 35 years of field experience in multiple disciplines: sheet metal fabrication, car electrical system, construction, plumbing, residential electrical, and HVAC systems. We're fully licensed, bonded, and insured for your peace of mind. We take care of your needs.

Do you offer maintenance plans?

Yes!... and no. What do we mean by that? We do things a little differently here at Sun Tech Air. Rather than charge you monthly for service that may or may not be done thoroughly (like some of the big guys), we prefer to touch base with our happy clients twice a year.

Full system clean, check up, radiator refresh, blower check, the works. If we find something that needs servicing, we offer an instant discount and get you sorted as fast as possible.

For our repeat clients, we're working to add priority HVAC servicing and special discounts.

What payment option do you take?

We prefer cash and checks, but we're currently working to add card payments. Feel free to ask if you need more information.

How do I schedule a service or get a quote?

Call us directly to tell us a little bit more about your situation. We respond quick.
Usually same day.

What brands do you work with?

We service all major HVAC brands, including but not limited to:

• Trane

• Carrier

• Lennox

• Goodman

• Bryant

• Rheem

and we've serviced antique HVAC units as well. We can also recommend cost-effect replacement options tailored to your home and budget.

Can I write this off as a business expense?

Yes, if you're using your space for business (home office, studio, rentals, etc), HVAC maintenance or upgrades may qualify as a deductible expense, but make sure to double check with your tax advisor.
