"Philip came out the day before to take measurements in preparation for the impending work and discussed what would be done and the arrival time for the following day. He was extremely punctual on both. Took house paint that I provided so that all materials would be pre-painted in his shop and brought to the site ready to be used. Philip got right to work on arrival to do the soffit and fascia repair. I requested aluminum sheeting on the soffit to prevent reoccurrence of racoon damage that was color matched to the soffit and installed. He used proper safety equipment while working on the room, worked efficiently, cleaning up as he went. The shingles were replaced and sealed on the roof properly after the repairs were finished when the attachment of the safety harness was undone. Finally, he did a really nice job reattaching a sprung panel on a wood paneling sided chimney with screws and washers followed by recaulking the joint to prevent water penetration. I AM EXTREMELY HAPPY with the work done and have requested a quote for some additional siding repair work that will be undertaken later into the spring."

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.
