"We called Grove Heating and Cooling and appointment was able to be scheduled for an estimate within a few days. Mr. Kelly came to provide estimate and give recommendations for lower level heating/cooling. Estimate was reasonable. The job was scheduled within one week. Workers arrived on time, were considerate of the newly installed carpet by wearing shoe covers. Worked diligently and completed the job ahead of the estimated time (6 hours instead of 8 hours). Cleaned the work area. Foreman for the job explained what had been done, showed me the completed work. Very professional. Would definitely recommend."

"I hired them to come and install an exhaust fan as well as a thermostat. After realizing my hvac system also had a humidifier function that was incompatible with the thermostat I bought they were able to properly install my exhaust fan (I bought the wrong kind as well) and hung a chandelier under two hours. Very efficient and fair pricing."

Heating and Air Conditioning questions, answered by experts

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.
