Common Reasons for HVAC Repairs in Charlotte, NC

Heating, ventilation, and air conditioning (HVAC) systems are complex machines with lots of moving parts that all work together to keep your home comfortable. But like any machine, your HVAC system may not always work perfectly. Various problems can come up that may require repair by a professional heating and air conditioning contractor. Many of these common problems can be prevented with some action on your part and regular maintenance by a professional. When you are looking for HVAC contractors in Charlotte, Andy Lewis Heating and Air Conditioning is a name you will certainly see, and the one you can rely on for dependable service. Andy Lewis provides quality repairs, preventative maintenance, and installation at affordable prices.

Reasons for repairs:

  • Dirty filters. The purpose of filters are to block dirt, dust, and debris from entering your heating and cooling unit. When they do their job right, they get dirty. If they are too dirty they impede air flow into and out of your system. This causes your furnace and air conditioner to work much harder than it should. In extreme cases dirty filters can cause your system to quit altogether. Andy Lewis recommends replacing your filters on a schedule to improve air flow and air quality. This is especially important if you or anyone in your household suffers from allergies. Filters remove allergens from the air when replaced regularly. This is one action you can take on your own to keep your HVAC system working well.
  • Lack of air flow. If you are changing your filters regularly, but still experience low air flow from your vents, it’s possible you have a mechanical issue like worn out belts, bearings, or fan motor. This is something you should hire a professional, certified technician to repair.
  • Pilot ignition problems. Furnaces create heat by burning fuels like natural gas, propane, and heating oil. In order for these fuels to burn and create heat, a pilot light or ignitor is needed to start the process. Older furnaces have pilot lights that stay lit constantly, but if it goes out for some reason, it may need to be relit. Newer furnaces have electric ignitors that only light when the furnace comes on. If this ignitor is faulty, your system will not create heat. A professional HVAC company can repair or replace your ignitor, or upgrade your old pilot light to an automatic ignitor.
  • Thermostat issues. The thermostat controls your furnace. It has a sensor that determines the temperature and calls for heat when the room temperature gets too low. If any part of your thermostat is malfunctioning, either the sensor or the computer, your furnace may not turn on when it needs to. It may cause your furnace to run constantly and overheat your home. If you do need a new thermostat, consider having a programmable thermostat installed. It allows you to set different temperatures for different times of the day and night, saving energy and lowering your heating costs.

Avoid costly repairs and save energy with preventative maintenance

If you want to avoid a furnace breakdown this winter, schedule preventative maintenance as soon as possible. There may be problems with your furnace that you’re not aware of, and when you switch it on that first cold night, it won’t work. Be on the safe side and have it tuned up ahead of time. You will also get the benefit of energy savings when your system is running more efficiently. Andy Lewis offers affordable planned maintenance agreements that include twice yearly tune-ups for your heat and air. Schedule maintenance or call (704) 391 9191.
