How to prevent catastrophic failure of your air conditioning unit

Improperly maintained or serviced air conditioning units can experience a catastrophic failures because parts that are worn out or unusually stressed break down and start cascading problems. Catastrophic failures cost hundreds of dollars fixing, and the added aggravation of finding oneself with A/C in the worst of weather conditions.

The best way to avoid this is to enter into a scheduled maintenance contract with an air conditioning company that employs NATE-certified HVAC technicians.

D&H recommends keeping your A/C serviced professionally on a regular basis by accredited NATE-certified technicians. In most cases, this is a mandatory condition to continue benefiting from your manufacturer’s warranty!

HVAC manufacturers will void their warranty if your system is not maintained all year long. Most likely, the manufacturer’s paperwork states it.

The first measure to take to prevent costly repairs on your air conditioning system is to ensure it is regularly maintained by qualified technicians.


If you bought your system so long ago that the manufacturer’s warranty has expired, your system may continue working but a failure will not be covered if the warranty has not been replaced by a maintenance contract.

Our recommendation is to get some coverage under a maintenance contract: such contract is not the same as a manufacturer’s warranty, but a good maintenance agreement will (a) ensure that NATE-certified HVAC technicians inspect and tune up your system twice a year, identifying any defective parts; and (b) ensure you get a discount on parts that need to be replaced.

Call D&H Air Conditioning to repair your air conditioning. Many of your neighbors of Canda Hills have, and we have references to give you. It is not by accident that we have recevied the Angie’s List Super Service Award multiple years: it takes a real company to provide excellent air conditioning repair service all year round, year after year.

Here is an example of a service call in Canada Hills, on N Olympic Place, AZ 85737 USA

-air conditioning repair service canada hills oro valley 85737We performed air conditioning maintenance and inspection on our customers’ two split-systems. We installed water safety on the attic system (to avoid any leak due to condensation drip). We also installed a compressor protection on the 5-ton condenser.  We inspected the air filters, the blowers and the evaporater coils for cleanliness. We also flushed the condensation lines and rinsed the condenser coils. We cycled both systems with a 22-25 degree temperature split: the refrigerant pressures were reading ok at this time. All motors and current controllers were operating within range. Both systems were operational when we left. The inspection and maintenance operation was carried out under the Family Plan (air conditioning service plan), at no extra cost for our customers.
