We're Morris Mechanical LLC, and we've been a premier heating contractor in Easton, PA, since 2014. We specialize in heating, air conditioning, and plumbing. We offer service installation, heater replacement, mini splits, new construction, emergency repairs, and much more. We're looking forward to partnering with Northampton, Bucks, and Warren counties to continue to offer a premier HVAC experience. We'd like to personally invite you to contact us for a tune-up, today!
"I’m not sure my words can express just how grateful we are to James from Morris Mechanical. Our AC died during this last heatwave at 4 A.M. and he responded immediately. He offered to come at 8. He was punctual, polite, and knowledgeable. What we hoped would be an easy quick fix was in fact not in the cards for us. He helped us understand our options, how the A/C unit functions and although he had other calls came back the same day to install a new unit and coils. Although I’m not thrilled with having to replace these items, I am thrilled that it was James who did it. We have tried 4 different hvac companies in the 5 years we have lived in our home and we will not use anyone other than james going forward."

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.
