Proper operation of your heat pump will save energy. Do not set back the heat pump's thermostat if it causes the backup heating to come on -- backup heating systems are usually more expensive to operate. Continuous indoor fan operation can degrade heat pump performance unless your system uses a high-efficiency, variable-speed fan motor. Operate the system on the "auto" fan setting on the thermostat.
Like all heating and cooling systems, proper maintenance is key to efficient operation. The difference between the energy consumption of a well-maintained heat pump and a severely neglected one ranges from 10% to 25%.
Clean or change filters once a month or as needed, and maintain the system according to manufacturer's instructions. Dirty filters, coils, and fans reduce airflow through the system. Reduced airflow decreases system performance and can damage your system's compressor. Clean outdoor coils whenever they appear dirty; occasionally, turn off power to the fan and clean it; remove vegetation and clutter from around the outdoor unit. Clean the supply and return registers in your home, and straighten their fins if bent.
You should also have a professional technician service your heat pump at least every year. The technician can do the following:
You wouldn’t drive your car 100,000 miles without changing the oil. The same logic holds true for your home comfort system. Regular HVAC preventative maintenance is the best way to ensure trouble-free operation and peak performance. Pre-season maintenance is also important. It can help to avoid a system failure in severe hot or cold weather when you need it most, and it can also keep your energy bill from getting out of control.
The old adage is true: an ounce of prevention is worth a pound of cure. Below you’ll find our Preventative Maintenance Checklist, which is our proven method to keep your system in the pink and your home in constant comfort.
»For a system that heats and cools: perform maintenance in the spring and fall
»For cooling system maintenance only: perform maintenance at least once a year, before the cooling season
»For furnace maintenance only: perform maintenance at least once a year, before the heating season.
The most common way to heat a house is with a furnace. And furnaces and air conditioners need their filters cleaned every couple of months. (How often you need to change them will depend on your filter and your furnace. You can see one person's cleaning ritual in this Energy Saver blog post from this spring.)
If your HVAC system is in dire straits, you may even want to clean out your HVAC ducts. This highly informative article from the EPA explains the entire process and explains when you may need to clean out your ducts and when you will not. They go to great pains to explain that just cleaning the dust out of your ducts will not necessarily increase the air quality in your home, though. And it certainly doesn't need to be part of your yearly home maintenance.
But no matter how you heat (or cool) your home, you want to make sure that the systems you're using have clean filters. This will ensure your appliances are working like they're supposed to. It could also help the air quality of your home, which will make life a little easier on those people among you who deal with allergies of any sort.
