"I never leave bad reviews but feel compelled to warn people not to use this man's service. The most unprofessional, short tempered and hostile man. I am a young mother with a 3 month old infant, so getting our hvac fixed is crucial. Vinny canceled on us last minute and rescheduled twice, he bad mouthed other companies who had worked on our system previously, he told us to run our own wires, and then called my father in law stupid for doing it wrong. When I interjected saying that that wasn't very nice and asked my father if we should call someone else, he became irate, yelled at me for saying something, said i ?should mind my business? in my own home, raised his voice loud enough to startle my infant and made him cry, said he ?should have pushed us down the stairs?, and stormed out of the house like a disgruntled prima-donna. The whole situation left me and my baby rattled. This man thinks that the demand for his trade entitles him to speak down to and mistreat customers.Go elsewhere."

Heat pumps rely on evaporation and condensation processes. The unit transfers heat through the system via a compressed refrigerant. The compressor within the pump circulates the refrigerant through two coils. The first coil evaporates the refrigerant and absorbs warmth from the air. The refrigerant then passes to the second coil, where it condenses, and the unit releases the absorbed heat.
A well-installed and well-maintained heat pump lasts an average of 12 to 20 years. Routine filter changes, annual tune‑ups, and prompt repairs help the equipment reach the upper end of that range, while skipped maintenance or poor installation can shorten its life and raise long‑term costs. Ask your heat pump installation pro for maintenance recommendations so you can get the maximum benefit from your unit.
Heat pumps are most effective in regions where winter lows remain above approximately 40°F. Efficiency starts to drop below that point and falls off sharply near 25°F. If you live in a colder area, look for a model with a high Heating Seasonal Performance Factor (HSPF) and plan on supplemental heat during deep freezes to keep energy use in check.
The biggest drawbacks are the upfront cost and poor cold-weather performance. Installation can require electrical upgrades or duct changes, and once temperatures fall well below freezing, the unit may need help from a furnace or electric resistance coils. Factor in those add‑ons, along with routine maintenance, when you weigh the long‑term savings against the initial investment.
