What are common air conditioning problems?

A lack of refrigerant is one of the most common problems that occur in an AC system. When the refrigerant level is low, the system will have trouble operating efficiently. Our specialists can determine the level of refrigerant in your air conditioner, then go about diagnosing the problem. A lack of refrigerant can also signal a leak somewhere in the system. We can help you locate the leak and either repair it or speak with you about other options. In short, our technicians can get your AC up and running again so you can be comfortable in a cool home.

A clogged condensate drain is another common problem with air conditioners. When this drain becomes clogged with dirt, algae, and other debris, your air conditioner is not able to operate at full capacity. We can check your condensate drain to see if there is a clog. If there is a blockage, we can remove the clog and get your AC running properly again.

Electrical problems are also fairly common with air conditioners. An AC may stop working due to a faulty connection or a worn wire in the system. We have the experience and the equipment to check your system for problems with the wiring.

What are common furnace problems?

A clogged air filter is a common issue with a furnace. If the air filter in a furnace is filled with dust, pet hair, or dirt, the system is unable to deliver an adequate amount of warm air to the home. We can change your filter and give your system a maintenance checkup to look for any potential issues.

If you are having trouble maintaining a warm temperature in your home, your thermostat may be the problem. A thermostat that offers an unreliable temperature reading can cause you to adjust the heat when you don't need to. Our technicians can run a check on your thermostat and address any problems that come up.

A worn-out fan motor is another common furnace issue to look out for. If this fan is not working properly, the system can't distribute heat throughout the home. Our professionals can diagnose the problem and replace the fan motor if necessary.

What are the benefits of replacing a faulty heating unit?

An inefficient heating unit can result in high-energy bills since the system is using more power than it needs to. An efficient heating unit is designed to conserve energy and can be used with less frequency. As a homeowner can save on your monthly heating bill with an up-to-date system. Give us a call and let us help you with your AC or furnace today!
