"One Hour Heating & Air has been servicing my HVAC system since I moved to Fort Collins four years ago. Greg Nieves is excellent. He took time to answer all questions and went out of his way to offer suggestions and make sure I understood everything.. This company is totally competent although their prices seem a bit high. However, their service is great and worth the price since I've never had to call them back with a complaint."

Heating and Air Conditioning questions, answered by experts

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.
