Preventative HVAC Maintenance Checkups for your Heating and Cooling System

Hvac Technician Performing Maintenance On System

Your heating and AC system works hard to keep you comfortable in winter and summer, and it usually does a pretty good job. But if you ignore the regular heating and AC maintenance your system needs to run its best, it's only a matter of time before you'll begin to experience the results of that neglect. You may begin to notice that your system isn't keeping you as comfortable as it used to. Your utility bills may increase. And if you let it go long enough, your system may end up malfunctioning and need repair.

On the other hand, with good preventive maintenance, provided on a regular basis, your heating and air conditioning system can give you dependable comfort and worry-free performance for years. At Dulin Mechanical Services, Inc., we offer the preventive HVAC maintenance checkups you need to keep your system running optimally during the Charlotte, NC area's chilliest winters and hottest summers.

The Benefits of Air Conditioning & Heating Maintenance

As your air conditioner, furnace or heater runs day after day, it's subjected to a certain degree of wear and tear. This is inevitable. However, to a great extent, the amount of wear and tear the unit or system receives is dependent on the amount of care you give it. Changing the filter as needed and getting the AC checked annually before the cooling season and the furnace or heating system checked each year before the heating season can yield multiple benefits. Some of these benefits follow:

  • More consistent indoor comfort in winter and summer
  • Higher energy efficiency leading to lower utility bills
  • Decreased likelihood of needing more expensive emergency repairs
  • Better indoor air quality through cleaner system operation
  • Optimal system performance: better heating, cooling, humidity control
  • Less-frequent repairs resulting in lower repair costs
  • Longer system lifespan, meaning less-frequent replacement costs
  • More dependable system safety leading to greater peace of mind
