  • "Fantastic, personal service. You don't end up waiting until the end of a 4 hour service window for someone to call you and say they are going to be a little late. I've had the owner and CEO come out to my house to present their products and check up on the work. Wonderful personal experience after dealing with the larger hvac companies."

  • "I am the type of reviewer that rarely writes a review. In fact, I only do so if I am extremely unhappy or very pleased. I remain very pleased, not to mention impressed, with Reliability Home, LLC's work. A few years ago, they came to my rescue and were able to put in a new HVAC system when my furnace died the week of Christmas. This time, they exceeded my expectations by being able to rework their schedule to get a new hot water heater installed the same day they came out for a diagnostic consultation. They will continue to be my go to..."

  • "My AC stopped cooling over the weekend so I called Reliability Home this morning. They had someone out 2 hours later! Everyone I spoke with was very professional and responsive. They showed me the readings and explained what they mean rather than just going about their business. I really appreciate their honesty and extensive knowledge. I would recommend them to others."

Furnace or AC Trouble?
Count On Us for Expert Diagnosis & Repair

Common Furnace Problems

Clogged air filter – 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.

Malfunctioning thermostat – 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.

Worn-out fan motor – 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.

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!

Common Air Conditioning Problems

Lack of Refrigerant – 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.

Clogged condensate drain – 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 – 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.
