The company is just great!! John is a very nice person. He helped me with my heater & didn't charge me a thing. It was a easy fix. He is one of the few honest people still left in this world who isn't out to just make a buck. If you have any problems I would call this company first!!

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.
