Maintenance Prevents Breaking the Bank

The #1 cause of system breakdowns is lack of maintenance of heating and cooling systems.

Regardless of age, brand or who installed your existing equipment, keeping it maintained saves you money. Equipment manufacturers require planned maintenance to validate and preserve their warranties. Good news, it’s never too late (or too soon) to start a proper maintenance plan.

Lower Your Energy Bills

Maintenance can help you lower your bills! When your heater is in good shape, it wont have to work as hard to keep your home warm and comfortable.

Extend the Life of Your Furnace

No one wants to have to replace their heating system prematurely. Furnaces that get regular maintenance last much longer than units that do not.

Save Money

With regular furnace tune-ups, you can avoid the need for costly repairs in the future. It is much more cost-effective to prevent problems than to deal with them after the fact.

Stay Comfortable

The purpose of having a furnace in the first place is to help you stay warm and comfortable. With preventative maintenance, your unit will work effectively.

Experience Pays Off 

With 55+ years in installing, maintaining and replacing air conditioning and heating systems in the greater Tucson area, we can confidently say we have seen absolutely ALL sorts of issues with air conditioning systems; Our very extensive experience gives us an edge over almost all other HVAC companies in the region. There is not a single problem we haven’t seen in all these years. 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.

Manufacturers have started limiting warranties based on cascading issues: a badly maintained system causes problems in another system and another system, etc. This means that manufacturers are no longer forced to change entire systems for issues that could have been avoided very easily with maintenance. Regular maintenance reduces the risk of cascading issues: when an A/C system does not operate optimally in any compartment, planned maintenance and failure detection systems isolate critical issues before they contaminate other parts of the system and become extremely costly to repair. Heating and cooling equipment manufacturers like Daikin publish maintenance guidelines that are very useful.


The difference between a well-maintained heating and cooling system with regular maintenance and a poorly maintained system is the cost for the owner. Most manufacturers will NOT cover warranty repairs due to a lack of preventative maintenance. Daikin offers maintenance plans through D&H, one of their approved Comfort Advisors.


It just makes “dollar sense” to equip yourself with great heating and cooling maintenance 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.
