Service Tech came within designated time. Called before he came, gave me his name. Did a thorough job cleaning the heating unit. Made me aware of things that need to be looked at. Said he would follow up after speaking with a supervisor about duct work installation problems. Friendly, courteous, knowledgeable.

Came out the same day, fixed the problem at a reasonable price, and were very professional and knowledgable. This after another firm said I needed the unit replaced at a cost of 5,000 dollars. Be careful who you call.

Not only did Chris Moore do a great job servicing our unit, he went above and beyond his duties. We had tubs and boxes in our garage blocking the path to part of the unit he needed to service that I had forgotten were there. Since I was holding my 6 month old son, he so kindly moved all them out of the way, did his job and even moved them back when he was finished. He never complained and volunteered to do it for me. He was very polite and understanding. Thanks again Chris!!

Paul was especially professional and friendly, and he communicated exactly what was wrong with our unit going so far as to show me the capacitance readings of our unit's blown capacitor. He went above and beyond the basic service call by checking for and finding additional problems that likely would have caused calls later. Paul is a champion of customer service!

5 reasons: Johnny Jones was a 10 discussed the problem and pointed it onto Justin Sharp, who explained the problem and solution. Barry Henry and Jeff Guterio who designed and installed the equipment bringing new comfort and peace of mind and Mick Mcgusran, who was accessible to us throughout and along with all his men showing knowledge of their job, professionalism, courtesy and friendliness. Showing us we had chosen the right company. It was a good experience.

Tips & Advices
You can keep your air conditioner running efficiently with some preventative care measures. Shut off the power to your AC before cleaning it or performing any of these tasks:  clean your filter at least twice a year; remove leaves and twigs from cages; clean the fins with a garden hose or special spray, then use a butter knife to straighten any that are crooked; keep your yard clean so the fins won't get blocked; cover the unit up for winter; and make sure it's level or you run the risk of damaging the inner workings of the unit.
To clean your air conditioner drain, first shut off the power to your unit at both the thermostat and the breaker. Then remove the drain pan. If the pan is full of water, soak up the liquid with a few towels or rags or use a wet vacuum. You can use a solution of water and distilled vinegar, or substitute peroxide for the vinegar, to clean out the drain pipe. Let the pipe sit for a while in the solution and then put all the parts back in place. Once you start using your air conditioner on a regular basis, check it periodically to ensure condensation isn't building up.
If you happen to live in a hot and humid area of the country, drainage problems can occur with your unit since moisture can trap itself inside the system. Routine maintenance can cut down on drainage issues by cleaning out any mold or algae from blocking the drain. If you notice moldy smells whenever you turn the thermostat down, check on your system.
If you notice your system is acting inconsistently, the sensor is most likely out of place. Turn off the unit and reach behind its control panel while carefully bending the sensor back into place near the evaporative coil.
Find out where the noises are coming from. A banging or clanking sound could be due to a loose part. If you hear a hissing sound, it's most likely because of a refrigerant leak and you should contact an HVAC technician as soon as possible.
