Providing High Quality Heating Maintenance Services 

At Controlling Systems, we encourage customers to schedule an annual service tune-up and cleaning before operating your furnace for the winter. Fall is the best time to perform furnace maintenance, so your system will be ready when it’s time to fire up your furnace during the winter months. The purpose of the service tune-up is to keep your system running at top efficiency throughout the season, so you have heat whenever you need it. 

We provide maintenance for all heating systems, including:

  • Boilers: A boiler is complex and requires a professional hand on an annual basis to clean and check it. During your maintenance service, our professional technicians will clean and check your boiler’s burners, combustion chamber, heat exchanger, controls, vents, tank, pipes, belts, anode rods, connections, drains, linings, and all connected components, as well as your thermostat(s) and smoke and carbon-monoxide detectors.
  • Furnaces: Our experienced technician will clean and check your furnace and ensure all the connections, controls, sensors, drains, motors, ducts, valves, and blowers, as well as your ignition assembly, thermostat(s), and smoke and carbon-monoxide detectors are in good condition. Following your tune-up, our technician will instruct you about next steps or any work you should do between service visits.
  • Heat Pumps: For heat pumps, an annual service tune-up and cleaning is recommended, usually performed in the fall, same as furnaces and boilers. Our professional technician will check and clean filters, blower, indoor coil, ducts, refrigerant, electric terminals, connections, motors, and belts, as well as lubricate all working parts. Be sure to change or clean the filter every three months or as needed. You can also clean the outdoor coils whenever they seem dirty and keep yard debris and vegetation away from the unit.

Thorough and Timely Air Conditioner Maintenance

For air conditioners, an annual service tune-up and cleaning is recommended. We suggest you schedule AC maintenance during the spring. Our Denver AC maintenance technicians will check and clean the connections, coils, blower components, lines, refrigerant, drain, fuses, and thermostat(s), as well as lubricate all working parts. You can perform limited maintenance on your system between visits.  you You can start by removing any yard debris or vegetation from the top and sides of your outdoor air conditioner unit. You should also consider protecting your air conditioner with a tarp during the winter months.

Affordable Air-Filtration System Maintenance

For air-filtration systems, regular maintenance is something you can perform on your own. Maintenance on an air-filtration system usually just means changing or cleaning the filter every three to nine months. Begin by checking the manufacturer recommendations for your system. Changing or cleaning your filter on a regular basis will ensure the best filtration for your home as well as extend the life of the system.
