D&H AC offers air conditioning repair services to all residents of Vail, AZ

D&H Air Conditioning & Heating has been serving the Greater Tucson area since 1959. We have been installing and providing air conditioning repair services in Vail since the early 1970s. At that time, Vail still counted just a few hundred homes, it was all before the town expanded in the early 2000s.

The reason why you see D&H’s trucks often in Vail is only due to the word of mouth that we have been benefiting from, thanks to our awesome customers. Happy families gave great recommendations to their neighbors, and the neighbors called us for air conditioning repair service or new air conditioning installations. We served them well, and they in turn started to recommend D&H.

  • The age of your A/C unit does not matter at all: we see air conditioners that are older than 20 years. We even see swamp coolers that were probably built before the home on which they are installed.

Since 1959 D&H Air Conditioning has installed thousands upon thousands of HVAC units. Over the years we have worked on tens of thousands of different makes and models of A/C, and most brands still existing on the market today manufacturer reliable, durable units. Those who didn’t are long gone.

However, with 60 years of experience in the Tucson market, we have found out that some brands are much more adapted to the local weather conditions than others. In Arizona, any air conditioner has to contend with extreme heat, extreme dryness, harsh sun, cold winters, dust and storms. In Vail, thunderstorms create spikes in the power grid that can burn HVAC motors and cost hundreds of dollars in damages. Vail is also exposed to dust: with the harsh sun, dust bakes into the coils of an A/C unit causing restriction in air fow and overheating of the unit. Again, this drives up power usage, creates stress on the air conditioners and shortens their life span.

But also very importantly, over the last few years we have seen some brands take a real lead in manufacturing energy-efficient A/C units. In view of the cost of electricity in Vail and Tucson, having an energy-efficient HVAC means big savings. Energy-efficiency also results in less stress on the units, because the motor speed will vary according to the temperature inside the home, and will progressively increase or decrease based on measurements — instead of hard-starting like AC units with one-speed motors.

If you are thinking about replacing your HVAC, you may be interested in requesting one of our technicians to come to your residence to perform some measurements. These measurements will help determine:

(1) what is the right tonnage of air conditioning you need for your home;

(2) based on your power bill, how much a variable speed motor could help you save;

(3)  based on the way you like to live, what is the most adapted A/C for you;

(4) what financing options do you have; etc.

These preliminary steps help you select the right air conditioner for your residence, within the budget that is yours.

Servicing air conditioners in Vail – Our technicians tell their stories

S Houghton Ocotillo Preserve Vail AZ

In the beautiful area of the Ocotillo Preserve, down in Vail, at the very end of S Houghton.

We performed a seasonal cooling tune-up on an Amana heat pump split system. We checked operations, pressures, temperatures, amp draws, and starting amps. Starting amps on compressor at 26+ currently.

We tightened all connections, washed the condenser coils, tested the current controller. Then we inspected the indoor unit, cleared the condensate trap, and inspected the evaporative coils. We observed signs of corrsion on the coils. We changed the filter.

Our recommendations under the Guardian Plan was to install a hard-start kit to reduce compressor starting amps and prolong the service life of the unit. We also recommended to install coil guard to prevent corrosion from spreading and further damaging the coils.

North Drystone Court Vail AZ 85641

On a service call on N Drystone Court, on the East side of Vail, in the Whestone Ranch area. Our customer called us because his unit 1 was not cooling. We noticed the pressures were a bit low at 80/250 PSI with a 72/77 degree temperature split. So we added 2 lbs of refrigerant and Super Seal (to help with the leak). The Super Seal product is not 100% effective, but it will work in most cases. After the fill-up, the refrigerant pressures were reading at 125/320 psi with 53/77 degree temperature split.

Verifying the amps we found the compressor amped @ 9.6/17.9, the condenser fan motor amped @ .57/1, the blower motor amped @3/5. We replaced the 45/5 uf current controller. Our client’s A/C unit 1 is now operational.

On unit 2, we recorded refrigerant pressures @ 125/320 PSI with 52/77 degree temperature split. The compressor amped @ 5.8/9, the condenser fan motor amped @ .3/.5. We replaced a charred contactor (maybe a power spike due to a thunderstorm, usual in the area). The second unit was fully operational when we left.

East Wetstones Road Vail AZ 85641

On East Wetstones Road, on the east side of Vail (85641). Our client called us a her home had been hit with a power surge during a storm and she felt her AC wasn’t functioning properly.

We checked and tightened the electrical connections. We checked the compressor running amps, the condenser fan motor running amps and the blower motor running amps. Nothing to worry about.  We checked the current controller and inspected the evap coils. We checked the split temperatures, all normal. We verified reversing valve operation.

We replaced the surge protector, damaged. And the Schrader valve, also damaged but for other reasons.

Our client’s unit was heating and cooling normally when we finished our service inspection.
