"I had a tune-up scheduled for Saturday 10-2. They called Saturday at 9:40 AM to cancel and reschedule because they were too busy. Obviously they make more money on service calls than their loss leader tune up special. Pretty sure they were hoping our system would not work and we would need a more expensive service call. Don?t waste your time and money on their shenanigans "

"Do not use this company! The have horrible service! Their technicians do not know what they are doing. They will never show up on time and will not keep you in the loop on what is going on.

I could never get in touch with anybody from the company or the technician."

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.
