Water Heater Repair & Installation

If your heater has stopped working or you’re simply looking for a new one, the trained technicians at CPH can install one of our long-lasting gas furnaces or heat pumps to heat the area you live or work. Our heating service also provides fast repairs and preventative maintenance to makes sure your products are up to date.

Boiler Repair & Installation

Most homes are heated with either furnaces or boilers. While furnaces heat air to keep your home warm and distribute the heat through ducts, boilers heat water and distribute that heat through radiators. While gas and oil boilers are typically less energy-efficient than furnaces and heat pumps, there are still many high-efficiency models available.
