"Fred was wonderful. He converted my new stove/range from Natural gas to propane. In the process, he fixed the gas lines coming from outside the home to the range. Even though it was a small project, he was out very quickly after my call. I expect to be hiring Meredith Plumbing and Heating again for a different project."

My name is Jay Scannell and I enjoy cleaning and making things spotless. My mother always made sure our house was clean as I was growing up and naturally I have liked to follow those similar footsteps and take it that one step further. I’d enjoy cleaning for you and your family if need be and I am open to anything you throw at me:).

Heating and Air Conditioning questions, answered by experts

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season. 

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.
