AC Installation

Bad installation is at the root of many air conditioning problems. An oversize unit turns on and off too often, allowing too much humidity to remain in the home. An undersized unit has to work too hard to cool the space on hot days, shortening its life expectancy. Bad duct design makes some rooms too hot and others too cool.

With such a large investment at stake, it pays to choose an AC contractor with years of experience and a stellar local reputation. Your satisfaction is our top priority, and our goal is to do the job right the first time.

Preventive Maintenance

The two most important things a homeowner can do to protect their air conditioner are actually very simple. First, change the air filter regularly. Second, schedule an annual maintenance check, preferably during the spring. The beauty of performing regular, routine maintenance is that it gives you the chance to catch small issues before they can become big problems.

Our certified service technicians follow a thorough checklist as they assess the condition of your unit, find any worn parts, clean away dirt, check the drains and tighten loose connections. A little TLC could prevent an inconvenient breakdown and contribute to a longer operating life for the system.
