Maintenance & Repairs

Preventative Maintenance

Your AC system should matter more when it is working than when it is not. As we have mentioned before, “just because it’s behind the walls does not mean it is not there.”

It is your home and the choice is up to you, but if you neglect your AC system than one day you WILL experience premature failures, higher electric bills, bad air quality and possibly mold growth.

We have priced our maintenance at a break even level. Our goal is not to profit from maintenance, but to expand our customer database and be the company you choose if you need a repair or when you finally decide to replace your AC system.

By allowing us to maintain your system you get lower electric bills, you get 15% off every single service repair and you will never pay overtime diagnostic rates. Our checklist ensures nothing was left untouched.

RepairsWe have never been more proud of our service staff. We have 5 dedicated service men who combined have 85 years in the business. Their trucks are stocked with as many universal parts as possible and they are ready to take great care of our customers.

$77 is our charge for diagnosing your residential system during normal business hours. We do not offer free diagnostics with repairs like some companies do. The main reason for this is because we do not want to increase our repair prices in order to compensate for not charging diagnostics.

Once we have found the problem we then discuss it with you and request your permission to proceed with repairs. We warrant our work and we warrant the parts we use.

It is a simple process without corporate sales pressure.
