"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

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.
