PTAC Repair and Replacement in Union, NJ

That comes from a load calculation on your actual house — floor area, insulation, window area and orientation, ceiling height, air leakage. It does not come from matching the old unit, which was frequently oversized when it was installed. Oversized cooling short-cycles and leaves a house cold and clammy rather than cool and dry.

Cold-climate models do, holding useful output well below freezing, and most installations here keep a backup for the coldest stretches. What decides it is your current fuel cost against your electricity rate, and which New Jersey incentives you qualify for — the state Whole Home program and your electric utility stack, and the amounts change from year to year.

Ask for three things and check them: current liability insurance, the appropriate license for your municipality, and EPA Section 608 certification for anyone handling refrigerant. Ask to see the documents rather than taking the logo on the van as proof. For gas work in particular, licensing exists because the failure modes are carbon monoxide and fire.

Yes. Ask the contractor for the findings in writing so a landlord or managing agent can act on them. In apartment buildings the usual complication is what the building permits — which equipment, mounted where, and by whose contractor — so that is worth establishing before anything is ordered.

A good deal. About 48% of homes in Union were built before 1940 (US Census ACS 2023), which usually means radiators rather than ducts, and that decides most of what follows. Heating is a boiler question — venting, balancing, cold radiators — rather than a furnace one. Cooling has to arrive without ductwork, so ductless heads, PTACs or window units are the realistic options. And a high-efficiency replacement often leaves the water heater alone on a flue that is now far too large for it, which needs addressing at the same time rather than later.

Steam systems heating some rooms and not others, which is almost always venting rather than a failing boiler. That pattern is regional rather than universal — the dense pre-war core — Newark, Jersey City, Hoboken, Bayonne and the Oranges. It is worth knowing before you book, because it tells you what someone should be looking hardest at here.

Usually yes, and that is the normal repair. The sleeve and exterior grille stay in the wall; the chassis slides out and a new one slides in. It is why PTAC replacement is quick compared with anything ducted.

Condensate that is not draining — a blocked drain path, or a sleeve that has lost its outward pitch. Both are common and both are usually a straightforward fix.
