Air Conditioning Preventative Maintenance

Airstream Services recommends air conditioning preventative maintenance in Murfreesboro, TN every spring to ensure an efficiently running unit that does not cost you unnecessary money out of your pocket. Think about it, you wouldn’t drive your car 100,000 miles without changing the oil. If you did, the car wouldn’t last long and would cost you a fortune in repairs. The same logic is true for your air conditioning and HVAC systems.

When Should I Do Furnace Maintenance?

Airstream Services has noted our preventative maintenance checklist below to help keep your HVAC system up and running even longer and in peak performance. For a system that heats and cools, perform maintenance in the spring and fall. For cooling system maintenance only, perform maintenance at least once a year, before the cooling season. For furnace maintenance only, perform maintenance at least once a year, before the heating season.

While your system is Operating

  • Monitor system starting characteristics and capabilities
  • Listen for abnormal noise
  • Search for source of unusual odors
  • Monitor air conditioning and heat pump systems for correct refrigerant charge
  • Measure outdoor dry bulb temperature
  • Measure indoor dry and wet bulb temperature
  • Measure high and low side system pressures
  • Monitor gas furnace for correct line and manifold gas pressure – make adjustments as needed
  • Measure temperature rise and adjust airflow as needed
  • Check vent system for proper operation
  • Monitor system for correct line and load volts/amps
  • Monitor system operation per manufacturer’s specifications
  • Provide system operation report and recommend repairs or replacement as necessary

Air Conditioning System Maintenance

  • Set the thermostat as high as comfort will permit.
  • Make sure attics are adequately ventilated to relieve heat buildup. If necessary, improve airflow by adding or enlarging vents.
  • When building a new house or renovating an old one, choose light-colored roof shingles to reflect more of the sun’s heat.
  • During moderate weather, don’t use the air conditioner unnecessarily.
  • Draw blinds or drapes to block the sunlight during the hottest part of the day.
  • Install awnings over windows exposed to direct sunlight.
  • In the cooling season, don’t run kitchen and bath exhaust fans longer than necessary.
  • Don’t place lamps, TV sets or other heat-producing devices beneath a wall-mounted thermostat. Rising heat from that equipment may cause the air conditioning system to overcool your house.
