Heating Maintenance,
Repair, and Replacement

Heating Maintenance. No matter what type of heating you use in the winter, a professional tune-up can make sure it runs as safely and efficiently as possible all winter long. All heaters require annual maintenance for the most satisfying usability. It doesn’t matter if you have a standard furnace or run a heat pump, an annual maintenance check is vital for safe operation and the preservation of its ultimate lifespan.

During a tune-up, your technician will inspect parts for optimal functioning, clean and lubricate internal workings of the heater, calibrate the thermostat, and check for repair needs. To keep your heating in top shape, it is recommended that homeowners schedule a tune-up every year after initial installation even if everything seems to be functioning fine.

Cooling Maintenance,
Repair, and Replacement

Air Conditioning Maintenance. You may know to switch out the air filter every few months and clear any leaves and other debris from your outdoor unit to keep your air conditioner in working order. However, a professional tune-up is also recommended yearly for optimal performance. A technician will measure the refrigerant levels, check for leaks, clean the coils, and inspect internal parts for repair needs during an air conditioning tune-up. All of these actions help your air conditioner lasts as long as possible and save you money on your cooling costs by running most efficiently.

Air Conditioning Repair. Few things are more frustrating than needing air conditioning on a hot day and discovering your unit has quit working. While there could be several issues causing your malfunctioning air conditioner, our trained professionals know which signs to look for when diagnosing an air conditioner problem. Some issues are simple to reverse if caught soon enough. Prolonged neglect, however, can lead to a premature replacement need. If you suspect something is off with your air conditioner, don’t hesitate to give us a call for an accurate diagnosis.

Air Conditioning Replacement. With regular maintenance and upkeep, you can expect your air conditioner to last between 8 and 12 years. When it’s nearing the end of its usefulness, you may notice the following warning signs: the home isn’t cooling down enough or it’s cooling unevenly, you notice loud noises or odd smells coming from the unit, your energy bills are extremely high, or liquid is leaking from the unit. Many times, you are better off getting a replacement than opting for an expensive repair that may only last a few more seasons.

We had Over the Moon do a maintenance service on our AC system. Took advantage of their $99.00 service special. The technician Mike was professional, courteous and did a thorough job.
