AC Repair

Some of the most common problems that require AC repair include:

  • Drainage – If you see pooling liquid or drips, you could have a clogged condensate drain.
  • Ductwork leaks – If some rooms are too warm/cold, there might be ductwork leaks.
  • Electric control failure – Wire and terminal corrosion is a problem in some systems. Your Mason, OH heating and cooling repair pro will check electrical connections and contacts during a service visit.
  • Inadequate maintenance – Dirty AC coils and filters are standard problems because of poor maintenance. The compressor or fans usually fail prematurely due to low/no maintenance.
  • Noisy motor bearing/internal belt – Your AC system has a lot of moving parts we lubricate during a maintenance visit. You should never hear more than the sound of air quietly circulating throughout your home. Clangs and thumping noises indicate a problem.
  • Refrigerant leaks – Simply adding refrigerant isn’t the fix, and it’s a dangerous job that’s not suitable for DIY. You need a trained professional to repair the leak(s).
  • Thermostat sensor – The thermostat sensor is behind the control panel. If it has a problem, you could have erratic cycling; the AC could run nonstop or barely at all.
  • Warm air instead of cool air – If it’s not a thermostat problem, we will check your filters and refrigerant.

Heating Repair

Some of the most common problems that require furnace repair include:

  • Air filter – Dirty or clogged air filters can cause a multitude of HVAC problems.
  • Ducts/vents – Dirty air ducts force your furnace to work harder (and your energy bills will be higher).
  • Electrical connections – Corrosion is a problem in some systems. Your Mason, OH heating and cooling repair pro will check switches, breakers, and electrical connections/contacts.
  • Pilot light – Dirty intake valves can cause a faulty pilot light. If your gas furnace pilot light burns any color other than blue, contact your local furnace repair professional as soon as possible.
  • Thermostat – If you have a thermostat problem, it’s a good time to have a smart thermostat installed.

Most of these repairs are avoidable with regular maintenance. Call (513) 621-4620 or contact National Heating and Air Conditioning. We provide ethical, affordable service to our friends and neighbors – like you – because we live here, too.

When should I have my HVAC system serviced?

National Heating and Air Conditioning recommends servicing your heating and cooling equipment at the beginning of each season. For example, your air conditioner should receive routine maintenance at the end of winter to prepare for the cooling months ahead. Likewise, your furnace should have scheduled maintenance at the end of the summer or beginning of fall.

How often should I replace my HVAC air filters?

You should plan on replacing your air filters at least once every three months; however, you may need to do so more frequently if you use your HVAC system more regularly. It’s extremely important to adhere to a regular schedule for replacing your air filter as this will help improve system performance and prevent against unnecessary repairs. Replacing your air filter regularly will also help improve your indoor air quality and reduce the number of airborne contaminants circulating throughout your home.

How do I know when it’s time to replace my air conditioner?

The short answer? An air conditioner that’s older than 10-15 years likely needs replacement in the near future. Other symptoms that can indicate the need for repair include excessive noise, strange odors, insufficient cooling, and inaccurate thermostat readings — just to name a few. Learn more about air conditioning replacement on our service page.

Are annual furnace cleanings actually necessary?

Yes, they are! Cleaning your furnace will help ensure it operates at peak efficiency and performs the way it should throughout the season. Not only that, but many manufacturer warranties can become invalid if owners fail to keep up with annual cleaning recommendations outlined in the warranty.
