Air Conditioning Maintenance

We provide comprehensive maintenance plans to help you avoid costly A/C repairs or replacements.

The best defense against costly repairs or replacement is a comprehensive maintenance plan. DNM’s experts will inspect your system in the Spring and Fall to ensure you get the most out of your investment. Vents blowing warm air, the air conditioner shutting off and on at random intervals, and an increase in allergy-like symptoms are all signs that your air conditioning unit needs to be repaired. If you notice any of these signs, DNM Heating & Cooling can help you diagnose and fix the problem.

Ductless Splits

DMS systems are a good choice for retrofitting an existing home or for adding zone cooling in a new home.


Ductless mini-split heat pumps are a good choice for retrofitting a home with a non-ducted heating system or adding A/C to a new home that doesn’t require a lot of cooling power. Mini-splits have two main components: an outdoor compressor/condenser and an indoor air handling unit. They are easier to install over other types of space conditioning systems and offer more interior design flexibility than other add-on systems.
