"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."

"We would HIGHLY recommend J & L Mechanical for all your AC & HVAC needs!! Their customer service, prompt response time and execution at installation was amazing. When they came to install the system, they were on time, friendly, respectful of property plus went above and beyond to install our new thermostat which was not part of the "invoice". Thank you again!!"

Heating and Air Conditioning questions, answered by experts

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
