"Had a complete HVAC system replacement. Through the whole process, they did what they said they would do and within the time frame that I was told. They responded timely and answered all my questions and concerns along the way. I am an impressed customer and delighted to recommend Major League HVAC."

"I am a new homeowner and the broken water heater was my first major repair. After getting the run around from my home warranty company (AHS), I took matters into my own hands and went to the Angi app. I received a personal phone call within minutes of submitting request on a Friday and Done Right came out on a Saturday. Ryan was a professional, warm, and courteous contractor. He followed COVID protocols and had the new heater installed on Monday. Could not have been a better experience."

"Patsy Cicala has so much knowledge and experience and was able to dismantle the mess made by the plumbers and correctly configure and install the filter system. It is working perfectly now and we are enjoying pure filtered water. Mr. Cicala really saved the day! In addition to being experienced and competent, he is reliable, respectful and pleasant to work with. I definitely recommend him and will contact him again for any projects or services needed in the future."

Heating and Air Conditioning questions, answered by experts

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

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.

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.
