"Hired West Mechanical to install a bathroom exhaust fan and light fixtures. Exhaust fan was left with duct disconnected and wiring exposed. Called Customer Service multiple times over 3-week period to get an estimate to reconnect the duct and address the wiring, still unresolved with open permit. UPDATE: I received a call from one of the company owners when he was made aware of the issue. He apologized for what I experienced and said it was very atypical for the company. He arranged to have an electrician complete the work the next day. The work included installation of a new duct transition that was not in the original scope, which was done at no charge. West Mechanical also sent a Supervisor the day after the work was completed to verify that the work was done to my satisfaction. Although I was unsatisfied earlier, I recognize that not every job will go as planned and I have been very impressed by how West Mechanical has responded. I would not hesitate to use them in the future."

"Update 10/07 — I had an electrical issue with a washer/dryer (due to manufacturer error), and texted Tripped for help at 1pm. They had someone drive out immediately (my home is in a VERY remote location), and Marqus arrived by 3pm. The issue was fixed by 3:45pm. This company has EXCELLENT service, and I could not recommend them enough!"

Heating and Air Conditioning questions, answered by experts

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

Yes, a frozen AC unit can affect your indoor air quality since the reduced airflow won't be as effective at removing air pollutants, like dust and other allergens. Additionally, ice around the unit can create excess moisture, leading to mold and mildew that can damage your home if you don’t catch it early.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.
