They try their best to get to you asap while still working around your work schedule. He goes out of his way to try to save us money... I have never had any plumbing company do that!! And he teaches!

"I selected John Wilcox to install a new furnace and condenser, I had four companies bid on the project and selected John because he spent the most time reviewing the entire HVAC system and seeking specific solutions to my problem, exploring beyond just the units and following the duct work and flow through the house while educating me, never trying to sell me. The project occurred back in January and I purposely waited until I had both winter and summer to determine the full results before writing a review. John Wilcox and team were extremely professional through the entire experience and made sure the project met their standards and my satisfaction. The new system has had a tremendous positive impact, saving substantial money on our utility bills and a more consistent temperature and quiet system. Their bid was very competitive as well and I will surely hire them again for any HVAC or plumbing our property will need."

The last thing you want is for your AC to stop working in the middle of summer, especially when the one you have is currently draining your energy bills and your bank account! Did you know that a new air conditioning system can decrease home energy usage 10-40% over an older, standard system? New systems also use the newer refrigerant R410a which is better for the environment. You receive a full warranty and benefit from the yearly energy savings which actually help pay for the cost of your new system.

Whether you replace your air conditioner to save money or electricity usage, our desired result is always the same.

A mini split heating and cooling unit can resolve a problem in an area of your home where the temperature is uncomfortable. This could be due to inadequate design of the current HVAC system, or bad ductwork. Installing a mini split in one or more rooms avoids major repair work while providing the ability to control the temperature in each room.

People love the super efficiency of mini splits. The new heat-pump style of mini splits provides comfortable heating and cooling in rooms that are difficult to heat and cool any other way. Customers who’ve had them installed tell us they didn’t know how great they would be.

Why consider a mini split? First, to heat and cool a room that has a dramatically different temperature than the rest of the house. Second, to save money with high efficiency equipment. And third, to reduce the noise level.


  • Mini split diagnostics & troubleshooting
  • Installation of new units
  • Annual maintenance

If you require an expert to help with your mini split heating and cooling unit, get in touch with us today!

"The man and his assistant who came to fix a pressure regulator in our home were extremely nice, and took the time to explain everything and answer all of my questions. He even found another safety issue on our hot water tank that I didn't even know was missing. Extra points for not smelling like a box of cigarettes, too! I know that nobody wants to have to get a plumber, but we had to, and I'm glad we went with Wilcox. The lady on the phone doing the scheduling was extremely nice."

Many people ask if tankless water heaters are a good value. To help answer this question, ask yourself: Do I ever run out of hot water? How old is my current water heater? Will I benefit from having extra space near my current water heater if the tank is removed?

Tankless water heaters provide a never-ending supply of hot water. A typical model allows for the use of two showers and dishwashing at the same time. A good installation will be sized for your home and household usage.

Many customers who buy tankless water heaters want to help the environment by saving energy. Households with big garden tubs or jacuzzi tubs absolutely love tankless water heaters. And customers especially love not worrying about running out of hot water even with three teenage daughters in their home.

Backflow Testing

We expect clean and drinkable water when we drink and bathe. But what happens when water, chemicals or bacteria flows unintended into your water supply from a separate piping system? Backflow has the potential to create health hazards if contaminated water enters your water supply system and is used for drinking, cooking or bathing.

For this reason, building codes, the EPA, PA State Regulators and water companies require backflow devices to protect the public water supply. All commercial buildings, apartments, condos, buildings with integrated fire systems, farms, new commercial construction and new residential properties require backflow prevention devices.

At John Wilcox Plumbing and Heating, we are a licensed Master Plumber and hold special certifications in backflow testing from the American Society of Sanitary Engineering (ASSE). Our testing can include double check, reduced pressure zone, dual check and vacuum breaker.

"We have worked with John Wilcox for a few years to handle various plumbing & heating jobs — from the smaller repairs to larger projects that require strategizing and weighing options. It is a relief and pleasure to work with him and we would recommend him highly. Plumbing and heating jobs can require not only experience and skills, but the ability to size up a project, problem-solve, and to consider the big picture."
