FREE Maintenance Tips

With the proper maintenance and care, your home comfort equipment will operate economically and dependably. There are a few simple, routine maintenance operations you can do to help ensure the best performance and comfort from your system.


Before you perform any kind of maintenance, consider these important safety precautions...

  • Disconnect all electrical power to the unit before removing access panels to perform maintenance. Please note that there may be more than one power connection switch.
  • Although manufactures take special care to prevent sharp edges in the construction of their equipment, it's best to be very careful when you handle parts or reach into units.

Routine Maintenance

  1. Filter Change Check the air filter in your furnace or fan coil every 3 to 4 weeks. A dirty filter will cause excessive strain on your furnace, air conditioner or heat pump. Replace your filter when necessary, or clean it if you have the reusable type. (If you have a reusable filter, make sure it's completely dry before you re-install it.) The prefilter and collection cells of an electronic air cleaner should be cleaned at least two or three times per year.
  2. Clean dust off of your indoor coil. With a vacuum cleaner and soft-brush attachment, you can remove any dust from the top and underside of the coil. Make sure you only do this when the coil is dry. If you can't get the coil clean this way, call us for service.
  3. Keep your outdoor condensing unit free of debris. If you keep grass clippings, leaves, shrubbery and debris away from your outdoor unit, it should only require minimal care to operate properly. Check the base pan (under the unit) occasionally and remove debris, to help the unit drain correctly.
  4. If the outdoor coil becomes dirty, use a brush or a vacuum cleaner with a soft brush attachment to clean the surface. To clean dirt that is deep in the coil, contact your dealer.
  5. Make sure your outdoor unit stays in a level position. If the support for your split-system outdoor unit shifts or settles and the unit is no longer level, re-level it promptly to make sure moisture drains properly out of the unit. If you notice that water or ice collects beneath the unit, arrange for it to be drained away from the equipment.
  6. Inspect your furnace's combustion area and vent system before each heating season. If you find dirt, soot or rust, your system may not operate properly or at its peak efficiency. Call us, and do not operate your furnace until it is professionally inspected and/or repaired.
  7. Have oil-fired boilers inspected annually. Call us (303-975-8809) before each heating season to replace your oil filter cartridge and conduct a thorough inspection of the unit's operation.
  8. Clean your humidifier at the beginning of every heating season. Review your owner's manual for the proper procedure to clean the external and internal components of your unit. The evaporator pad should also be replaced before each heating season. If the water in your area is hard or has high mineral content, you may need to clean or service your humidifier more frequently.

Winter Season Tips

For Colorado, fall means forgetting about heating and air conditioning for a while. Crisp mornings and moderate temperatures during the day create a comfortable existence with lower-than-average energy usage. Right around the corner, however, is the first frost of winter and the promise of higher energy bills.

Is there anything you can do now to impact your energy usage? "Absolutely," The transition period between the beginning of fall and the first days of cold weather is the perfect time to evaluate your home's energy efficiency and weather resiliency, and service your heating system. All of these things, along with following a few other simple recommendations, can impact your energy usage.

Here are some tips for making your home as energy-efficient as possible:
  • Install storm or thermal windows and doors.
  • Caulk and weather-strip all windows and doors.
  • Tape and seal leaks in your duct system and coil enclosure. Consider adding insulation to your duct system.
  • Wrap your water heater with an insulated water heater blanket.
  • Seal gaps between heated and unheated spaces. This may be around pipes, ducts, fans or vents.
  • Consider installing ceiling fans with reversible motors. In the winter, fans push warm air that collects at ceiling level back down into the room.
  • If you don't have a programmable thermostat, consider purchasing one; programmable thermostats are a great way to control the temperature in your home for maximum energy efficiency.
  • Install adequate insulation. Recommended: R-30 in ceilings, R-13 in exterior walls and R-11 in interior walls and floors.
  • If you're in the market for a new home comfort system, select a high-efficiency, variable-speed heating and air conditioning system. The Annual Fuel Utilization Efficiency rating, or AFUE, indicates the efficiency of a gas furnace. The higher the AFUE, the more efficient the furnace. If your present furnace is ten years old or older, it's probably in the 60 to 70 percent AFUE range. That means you're wasting about 30 to 40 cents out of every dollar you spend for heat. By replacing your old furnace with a new, high-efficiency model with an AFUE of 80 or 90 percent, more of the fuel you pay for is turned into heat.
We also recommend having your heating system serviced prior to the heating season by the dealer who installed it. And here's what you can do during the heating season to impact your energy usage:
  • Close shutters and drapes during winter nights.
  • Set your thermostat at 68° or lower during the day.
  • When using your fireplace, turn your thermostat down.
  • Keep the damper closed when your fireplace is not being used.
  • Dust or vacuum the vents in your home to ensure the free flow of warm air.
  • Clean or replace the filter in your furnace at least once every 30 days during peak winter usage.
