Preseason Tune Up

To avoid an unexpected breakdown, furnaces and air conditioners require periodic inspection and service. A preseason tune up can be scheduled separately or included in a comprehensive maintenance agreement. As part of the service, technicians inspect and test critical components and calibrate the system to the manufacturer’s original specifications. Other services include a refrigerant pressure check, lubrication of all moving parts, cleaning the evaporator and condensing coil, changing the filters and adjusting the balance for proper air flow.


No matter how well an HVAC system has been maintained, it will eventually need to be replaced. Whether this is due to obsolescence or repeated malfunctions, older equipment is costly to operate and may lead to health and safety issues.

Modern air conditioning equipment is federally mandated to provide a minimum 13 SEER efficiency rating. The Seasonal Energy Efficiency Ratio is a measurement adopted by the Department of Energy that allows consumers to compare the relative efficiency of different brands and models of air conditioners. Replacing an older 10 SEER air conditioner installed in the mid-1990s with a new 13 SEER unit can save up to 30 percent on monthly energy costs.

Similarly, a furnace that operates at 60 percent efficiency exhausts 40 percent of the fuel it consumes as waste gas. A new furnace with a minimum Annual Fuel Utilization Efficiency (AFUE) rating of 80 will use 20 percent less fuel than the older model while providing a similar BTU output.


Heating and air conditioning equipment is complex, and when a system fails, HVAC contractors dispatch NATE certified technicians trained and certified in all aspects of furnace operation and the refrigeration cycle. These service professionals use a variety of analytic and diagnostic tools to quickly identify the source of the malfunction. At Davis Air Conditioning & Heating, Inc. our commitment to service is evident in our fully staffed service department and a well-stocked fleet of service vehicles.

Once inside the building, our service personnel maintain a low profile and try to avoid inconveniencing the customer. Faulty components are quickly identified, and we only complete the exact HVAC repairs required to restore full system functionality. When the job is completed, the invoice amount will never exceed the final estimate.
