How the job runs

AC Installation Close to Home

Every AC installation in town, residential and commercial, runs through the same load calculation, quote, install and test as any job of ours.

The drive along the beach road changes nothing about the work. What the house needs decides the size, and you see the full plan in writing before any equipment is ordered.

  1. Measure the load

    We run a "Manual J" load calculation room by room: the floor area, the windows, the insulation and the duct runs in the attic.

  2. Write the quote

    With the size settled, you choose the system, the brand and its "SEER rating", the efficiency rating, knowing every option on the table fits the house.

  3. Set the equipment

    The old unit comes out, the condenser goes onto its pad or stand, and the "line set" and drain run to the indoor coil.

  4. Test and hand over

    The system runs a full cycle while we read the air at the registers, and you get a walk through the thermostat before we leave.

Local Homes and Their Cooling Needs

A house built around 1984 has had its cooling equipment changed out before, while the ducts overhead stayed exactly where they were laid.

That mismatch is the problem we plan around. Ducts laid out for an older, smaller unit can starve a bigger, newer system of air, so before anything is sized we check them for leaks and loose joints and measure "static pressure", the airflow pressure that tells us whether they can carry it.

Joints that have opened get sealed with "mastic". Where the old equipment was "builder-grade", we tell you plainly what an upgrade buys you and what it does not.

What the air does to a system

Weather a System Faces Here

The air here carries a lot of water, so a new system has to dry the house as well as cool it.

Stand under the Friendship Oak on a July afternoon and you feel it: warm, still and wet. That same air sits on every outdoor unit in town and runs across every indoor coil.

Sized off the old label

Oversized

  • Cools in short bursts and shuts off, the "short cycling" homeowners notice as an AC that keeps turning on and off.
  • Stops before the coil has pulled the water out, so rooms end up cold and clammy at the same time.
  • Every extra start adds wear to the compressor.

How we size it

Sized to the load

  • Runs long, steady cycles that take moisture out of the air while it cools.
  • The "condensate line" is pitched and kept clear, because in this climate it drains water nearly every day of the season.
  • The "air handler" goes where its coil and drain can be reached and kept clean.

Beyond the new system

Repairs, upkeep and heat

After the install, it is the same call and the same quote-first way of working.

  • AC Repair When the Heat Peaks

    AC repair is the call when the house stops cooling, the unit cuts off too fast, or water shows up around the indoor unit. With this much rain in the air, the drain side works every day, and when the "condensate line" clogs the water backs up around the unit.

  • HVAC Services Through the Year

    HVAC services look after both sides of the system, cooling in the warm months and heat before the cold. Of the occupied homes in town, 66.9% are owner-occupied, and it is the owner who pays for a coil left dirty or a drain left to clog, so a yearly visit earns its keep.

  • Furnace Repair for the Cold Snaps

    Furnace repair is for heat that will not come on, blows cold or shuts off part way. The heat stays switched off through a long cooling season, so across the 7,614 homes in town the calls come in a rush when a cold front blows through, and a weak igniter or a dirty flame sensor is often what turns up.
