Air Conditioning Services

The air conditioning quit, or it runs all day and the house still feels damp. Two different problems, and the second one is the one most people here live with.

Air Conditioning

Cooling Here Is a Humidity Problem Before It Is a Temperature Problem

August on this shore is not really about the temperature. It’s the dew point. A house can sit at 74 degrees and still feel clammy, and the reason is almost always that the system is pulling heat out of the air without pulling enough water out with it.
That happens most often when the equipment is too big for the house. An oversized unit cools fast, satisfies the thermostat, and shuts off before it has run long enough to dehumidify. You get short cycles, cold damp rooms, and a compressor that wears out early. Bigger is not better in a marine climate. It is the most common sizing mistake we find out here.

Sometimes the fix isn’t the air conditioning at all. A whole-house dehumidifier tied into the ductwork handles the moisture the system can’t, and in a beach house that sits closed up for weeks at a time it does more for comfort and for mold risk than another ton of capacity ever would.

We’ve worked the Delaware shore since 2001 and we’re locally operated. Every technician who turns up at your door is background-checked, and we clean up before we leave. Call before you book and we’ll try to sort it out on the phone first, because a system that stopped cooling is sometimes a clogged condensate drain that tripped the float switch, and that shouldn’t cost you a visit.

What an Air Conditioning Contractor Gets Called For in August

01

AC installation

Changeouts and new systems: central air, heat pumps and multi-zone. Sizing is where these jobs are won or lost, and in this climate a system that is too big will leave the house damp no matter how new it is. Plenty of lots here sit in a flood zone, so the condenser goes up on a stand. That changes the pad work, the line set and how anyone gets at it for service later. We pull the permit, whether that’s the Town of Ocean View or Sussex County.

02

AC maintenance

A tune-up in spring, before the first hot stretch. Three things strand people in July more than anything else: a condensate drain that clogs and trips the float switch, a contactor pitted by salt, and a charge that has drifted low through a slow leak. Those are what we look at first. If your drain line has no cleanout tee, it is worth adding one.

03

AC system upgrade

Replacing a system that still runs, usually because the repair bills stopped making sense or because the house has never been comfortable. This is where the refrigerant question comes up. R-410A is being phased down under the AIM Act and new residential equipment now ships with the A2L refrigerants, R-454B and R-32. That does not mean a working R-410A system needs replacing. It does mean a major refrigerant repair on an older unit is worth pricing against a changeout before you commit.

Air conditioning questions we get asked

Can’t see vours? Call and ask – we’d rather answer than have you guess

Central systems, heat pumps, ductless mini-splits and multi-zone setups, residential and commercial. Heat pumps are the default in most construction here built since about 1990. Mini-splits turn up constantly in additions, sunrooms, garages and converted porches, because so many shore cottages were added onto a piece at a time. We work on the ductwork feeding all of it too, which is often where the actual problem is.

Usually the system is oversized. It cools the air quickly, hits the number on the thermostat, and shuts down before it has run long enough to wring the water out. You end up with a cold damp house and a compressor wearing out early. The fix depends on what we find. It can be longer run times from staged or variable speed equipment, a duct leak pulling humid attic air into the return, or a whole-house dehumidifier tied into the ductwork. Bigger equipment is almost never the answer.

It depends on what you have now and what goes in to replace it. A like-for-like changeout is the low end. A system that also needs new ductwork, a heavier circuit, or a stand because the lot sits in a flood zone is the high end. The efficiency tier you pick moves it as well. We’ll look at the house and give you a free estimate before anything starts.

Tell us the changeover date when you call and we’ll work to it. A lot of what we do in season is exactly this: a system that quit on a Thursday with a Saturday check-in coming. If we can’t make your window we’ll say so on the phone rather than let you find out on the morning the guests land.

Yes. We’re insured and bonded, and we carry a Delaware HVACR license.
