Quality service also means making reliable recommendations for your heating and cooling. Sometimes, repairing a very old AC unit is not cost-effective. With the financing options we offer, it can be much cheaper to replace it. (It also saves you a lot of money on utility bills). When you call D&H to receive an estimate for a new system, we send a certified specialist to calculate precisely the AC load your home needs. He works to define the right system for your budget. We can propose financing options, sometimes even with 0% interest, to make high tech more affordable. Your budget must be respected, and we know this.

What about indoor air quality? If your home is in the lower areas of Tucson, your life is affected by pollution more than in the Foothills. If you are in Vail or south-east Tucson, you will get more dust than in Dove Mountain. We know this (better than any company from Phoenix) because we are local! We can recommend the right filters and AC filtration systems for your specific area.

We have repaired, maintained, and install HVAC systems for 60+ years. We have seen all makes and models, the full evolution of HVAC technology since 1959. So, yes, we can repair and maintain them all, except when an AC unit is too old and its parts can’t be found anymore, or when a brand has disappeared from the market. However, it is important to understand that repairing an older AC unit is not always the right call. With each year that passes, the efficiency of your AC system decreases. A system rated 15 SEER 5 years ago is not 15 SEER today. It is closer to 10 SEER in fact. The right recommendation for an older unit may be to replace it with new technology that saves power ($$) and runs more efficiently throughout your home.

All the main HVAC brands today manufacture reliable systems. But it’s a fact some manufacturers offer longer warranties than others. This is the question to ask yourself when considering an HVAC unit. Why does this brand only offer a 5-year warranty on the major components, and not 12 years like that brand? Why is the warranty on certain parts shorter than on some other parts? As a rule of thumb, longer warranties indicate the manufacturer has more trust in the reliability of their systems. This matters to you because parts will inevitably fail and have to be replaced. You want maximum warranty coverage. Also, between 2 systems using roughly the same technology (heat pumps, for instance), why is one rated 16 SEER and that one rated 20 SEER? This matters to you because the system efficiency will impact your utility bill. Base your purchase decision on warranty coverage, efficiency, and the specifics of your home.
