"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

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.
