Most homeowners only call their heating and air conditioning companies when something goes wrong.  Waiting until the system is broken not only interrupts the comfortability in your home, but it can be very costly.  Some of the benefits of preventative maintenance include prolonging the life of your system, increasing energy efficiency, and having fewer breakdowns–– saving you money in the long run.

Dominion Service Company offers preventative maintenance on your furnace, air conditioning, and heat pumps.

  • Outdoor Coil Cleaning
  • Condensate Drain Flush

Heat Pump

  1. Improve air quality

Healthy home, healthy system, healthy you.  A highly skilled technician who knows the system can remove dirt and debris particles during routine maintenance and can advise you on proper air filter routines. Otherwise, particulate matter can accumulate and enter the duct system, spreading over your house.

  1. More energy efficient

The maintenance process includes inspection and cleaning blades, cooling coils, and other essential parts of the equipment.  Cleaner coils deliver cooler temperatures­––resulting in greater energy efficiency––than coils that are not receiving at least annual maintenance.

Similarly, broken or soiled parts can make the heating unit work harder to heat and maintain desired temperatures in your home.  If cleaned and maintained properly, your heating system stays operating at an energy efficient level. 

  1. Ensures comfortable living

During a routine maintenance visit, our expert technician inspects all essential heating and air conditioner components carefully.  If an irregularity or issue is found, we fix it on the spot.  That way, your air conditioner and heating equipment can stay running smoothly, without any uninterrupted comfort during those hot and cold months.

  1. Saves you money in the long haul

Regular air conditioning and heating equipment maintenance allows our home service professionals to keep your system in the best condition possible.  Any parts that are damaged or worn are for replacing, preventing further deterioration that would impede the system’s functionality.  Ongoing prevention saves you money down the road on costly service calls and repairs.

  1. Extends the life expectancy of your system

Routine maintenance supports your system to maintain the highest performance over its life cycle.  Prolonging your HVAC life is particularly viable in areas like Michigan, where heating and air conditioning units can withstand cold months and hot summers.  Ongoing maintenance is a perfect solution for keeping one of the most significant investments in your home running effectively and efficiently.  


Priority Service, Peace of Mind, and Savings is the slogan for our proven maintenance membership service that we offer to all our customers.  Join our regular maintenance program for heating and air conditioning to keep your home comfort equipment at peak performance.  Our membership service is designed to save you money for the long term by catching system issues early while keeping it running smoothly and efficiently.
