Air Conditioning Service & HVAC System Check

Air conditioning service the correct way

Our Guardian Plan extends the life of your equipment and reduces your operating costs and repairs. Our air conditioning service plans are available on your new HVAC system or existing equipment regardless of the brand or who installed it.  Even if we did not install your system, you can still call D&H Air Conditioning hotline at (520) 408-2665 and request a technical evaluation under our Guardian Plan for your specific installation. 

Regular 360° air conditioning service prevents breaking the bank

The #1 cause of HVAC system breakdowns is a deficiency in air conditioning service.

Regardless of the age, brand or even who installed your existing equipment, keeping it serviced to fctory specifications saves you money. In fact, HVAC manufacturers require planned maintenance to validate and preserve their equipment warranties. The good news is it’s never too late (or too soon) to start a proper A/C service plan.

When you sign up for our Guardian Plan, our air conditioning service and system check program, this is what you receive:

  • Expert service
  • ‘Front of Line’ priority
  • Preferential scheduling
  • Discounts on service calls
  • Extended repair guarantees
  • …And much more!

Experience pays off for you

With an experience of almost 60 years in installing, servicing and replacing HVAC systems in the greater Tucson area, we can safely say we have seen absolutely ALL sorts of issues with air conditioning systems. Our very extensive experience gives us a leading edge and ranks D&H AC among the very best HVAC companies in Tucson. Our Angie’s List Super Service Award of 2019 is a testimony to the quality of service we provide our customers.

Any part of an HVAC system can break and create problems for other parts, starting cascading issues that usually wind up with very costly repairs.

As years went by, air conditioning manufacturers have started to limit their warranties because of cascading issues: a badly serviced system triggers problems in another system and another system, etc. In the end, HVAC manufacturers were forced to change entire systems for issues that could have been dealt with very easily from the get-go. Planned air conditioning service and system check is the antidote for cascading issues: when an A/C system does not operate optimally in any compartment, planned service and failure detection systems isolate critical issues before they contaminate other parts of the system and become extremely costly to repair. HVAC brands such as Daikin publish maintenance guidelines that are very useful.

The latest generation of air conditioning systems give advance warnings of possible system failures and transmit these warnings to a central monitoring system. This enables HVAC companies like D&H to be alerted early of a malfunction or the sub-par operation of a sub-system, and to intervene early enough to avoid catastrophic failures outside of warranty clauses.

The difference between a well-maintained air conditioning system within a thorough planned service program (like our Guardian Plan) and a badly maintained system is the cost for the owner. Most manufacturers (if not all of them) will NOT cover warranty repairs due to a lack of preventative maintenance. In such a case, homeowners may have to foot a bill that can reach into the thousands of dollars. In commercial and industrial HVAC installations, these cost will mount up very quickly. Daikin knows this and offers HVAC service and system check plans through approved Daikin Comfort Advisors like D&H Air Conditioning.

It just makes “dollar sense” to equip yourself with a great air conditioning service plan that is thorough enough to detect the issues BEFORE they occur, and prevent them by replacing parts that are becoming too worn out to fulfill their function at a 100% performance level. Our Guardian Plan prevents those costly bills and complete system failures by assuring you of 360° inspections through the year, replacement of parts before they fail, and an overall great level of performance to lower your air conditioning bills.
