At Commercial Service, our priority it to keep your heating, cooling, and plumbing working in the most efficient manner. Whether you need seasonal maintenance or a repair, our trained technicians will guide you through the process.



Servicing your heating and air conditioning system on a regular basis is essential in keeping your home safe and comfortable. Today’s heating and cooling systems are highly efficient but require regular maintenance to keep them operating at peak performance. Without regular maintenance, the life of your furnace and air conditioning system can be cut in half.

Consider signing up for our Heating and Cooling Maintenance Program, where our technicians will inspect, lubricate, adjust, and clean your heating and cooling system in order to prevent potential problems. On top of that, you also get access to benefits like 10% off on annual services. For more information, download our Heating and Cooling Maintenance Overview. 

Our preventive maintenance service and inspection can:

  • lower utility costs
  • extend the life of your equipment
  • entitle you to a 10% discount on all labor and materials on HVAC service work for the entire year (excludes installations)
  • reduce repairs and emergency breakdowns by revealing potential problems that can be corrected before causing major heating and cooling repairs

Even if your system has no problems, our inspection makes sure that everything is working in the most efficient manner. Every kilowatt saved helps the environment and saves you money. For more information, download our Heating and Cooling Maintenace Overview.
