We maintain, repair and replace all brands of air conditioning systems

D&H AC provides Tucson homes and businesses with air conditioning repair, A/C maintenance and A/C installation services since 1959. Our NATE-certified technicians are trained to repair air conditioning systems of any brand and any age, in a rush and all year long.

When your system needs repair, we can perform an audit of what went wrong so that the true cause of the failure be accurately detected and fixed. This saves you money from further repairs.

If you call us to enquire about a new A/C installation, we will automatically perform an audit of your current air conditioning system and its usage: this will allow us to determine with you what AC system is best-suited to your needs over 3, 5, 10 and 12 years.

Lastly, we provide top air conditioning maintenance services with NATE-certified technicians and the Daikin Comfort Pro (TM) ultra-selective label.

When it’s time for heating and heaters…

We don’t often think about furnace and heater maintenance and installation in Southern Arizona because they are minimally used most of the year. If you already have endured a local winter however, then you know that freezing occurs and optimum furnace and heater operation is essential.

Our NATE-certified technicians are highly trained on the many differing types/brands of heater and furnace equipment. Whether your furnace is brand-new or forty-five years old, our team will use all its knowledge and experience to help increase its longevity.

If it is time to replace your unit, ask our service technicians or Comfort Advisors about possible lifetime warranties on heat exchangers. Click here to find out more about our gas heating furnaces.

WHY AN A/C MAINTENANCE PLAN MAKES SENSE

Many home owners mistakenly believe that when their air conditioning system fails, the manufacturer’s warranty automatically covers parts and labor. Yes, it is true but only if the system has been properly maintained all along. Proper maintenance by a qualified professional is a condition required for the warranty to be effective. Proper maintenance is documented by the professional, and under this condition manufacturers will cover most issues due to a defect in the unit. In many cases however, manufacturers stipulate in the documentation given to home owners that a lack of proper maintenance VOIDS their warranty. This could mean thousands of dollars of unnecessary expenses for the home owner.
D&H Air Conditioning offers a comprehensive maintenance program covering all the air conditioning units installed by ourselves OR by other installers. When we install an air conditioning system, we offer home owners to roll the cost of the maintenance program directly into the cost of the unit. But even if your unit has not been installed by our technicians, we still offer the same comprehensive maintenance program for your unit. Certain restrictions can apply, however. Call us at 408-2665 and ask for a specialist of the Guardian Planned Maintenance program.
