HVAC Installation in Greenville, SC

New Construction HVAC Installation in Greenville, SC

  1. Design. Before any equipment is ordered, we calculate the heating and cooling loads room by room based on the home’s plans, insulation levels, window specifications, orientation, and ceiling heights. That information guides equipment selection and duct design so each room gets the right amount of airflow.
  2. Rough-in. Once framing is complete, we install the ductwork, refrigerant line sets, condensate drains, thermostat wiring, and gas piping where needed. Careful planning at this stage keeps ducts out of exterior walls when possible, minimizes long runs, and positions returns for good air circulation.
  3. Inspections. We coordinate with local inspectors and make sure our work meets current mechanical and energy code requirements.
  4. Trim-out and startup. After drywall and finishes are complete, we set the equipment, install registers and grilles, connect the thermostat, charge the system, and run full startup testing.
  5. Final verification. We measure airflow and temperatures, check refrigerant charge, confirm safety controls, and make sure every room is receiving the conditioned air it needs.

New Home HVAC Installation in Greenville, SC: Design Choices That Matter

  • Zoning. Separate zones for upstairs and downstairs, or for the primary suite, let you control temperatures independently and avoid the classic hot-upstairs problem.
  • Equipment location. Placing the air handler or furnace in conditioned space rather than a hot attic improves efficiency and equipment life.
  • Variable-speed equipment. Inverter-driven heat pumps and variable-speed furnaces deliver steady, quiet comfort and excellent humidity control.
  • Dual-fuel systems. Pairing a heat pump with a gas furnace offers efficient heating most of the year with strong backup on the coldest nights.
  • Fresh air ventilation. Today’s tighter homes benefit from controlled ventilation that brings in fresh outdoor air without wasting energy.
  • Dehumidification and filtration. Whole-home dehumidifiers and high-efficiency filtration can be designed in from the start rather than added later.
  • Smart thermostats. Remote control, scheduling, and energy reports from your phone.

Called in morning and tech was available to come by same day. Was honest and up front about the issues with my unit, which ended up being a switch, instead of trying to push expensive repairs. Will definitely be using them again in the future. Thanks.

I can’t recommend him enough! He came out quickly, diagnosed the problem with my air conditioning, and had it fixed in no time. He was professional, honest, knowledgeable, and took the time to explain everything to me. His work was high quality, and he made sure everything was working perfectly before he left. After dealing with the stress of my AC going out, it was such a relief to find someone reliable who genuinely cares about their customers. If you’re looking for someone dependable, reasonably priced, and experienced, I highly recommend him. Thank you again for the excellent service!

I needed a capacitor at midnight and he picked up on the 3rd ring. Very cheap for late night after hours. Very reliable fella, when I got there he ran me through the process of repairing it myself on a AC unit he had. 5 stars great service.
