"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."

"I am extremely pleased with my services from Tripped Electric. From working with their administrative staff (Tessa) on scheduling, to the 4 electricians who worked at my home (Jacob, Skyler, Marcus, and Justin) -- this business could not be better at what they do or more professional. I would 100% work with Tripped again for any of my electrical needs."

Heating and Air Conditioning questions, answered by experts

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.
