PTAC Units in Charleston, WV   

Packaged Terminal Air Conditioner Installation, Repair & Maintenance Since 1979

When you are responsible for keeping every room in a hotel, apartment building, or care facility comfortable, a failed PTAC is not a minor inconvenience. It is a room you cannot rent, a resident who cannot sleep, and a phone call at the worst possible hour. Dodrill Comfort & Energy Solutions installs, repairs, and maintains packaged terminal air conditioners throughout Charleston, WV and the Kanawha Valley, and we have been keeping this region comfortable since 1979.

Whether you need one chassis swapped out tomorrow morning or a phased replacement plan for eighty rooms, our technicians bring the same approach: diagnose the real problem, quote the price before we start, and do the work right the first time. It is the reason we stand behind every job with our Fixed Right or It’s Free™ guarantee.

What Is a PTAC Unit?

A packaged terminal air conditioner, or PTAC, is a self-contained heating and cooling system that mounts through an exterior wall and conditions a single room. Everything the system needs — compressor, condenser coil, evaporator coil, blower, and controls — lives inside one cabinet that slides into a metal wall sleeve. There is no ductwork, no outdoor condenser pad, and no air shared between rooms.

That design is why you will find PTACs under the window in nearly every hotel room, assisted living apartment, and older office suite in Charleston. Each unit runs on its own thermostat, so one guest can set 68 degrees while the room next door sits at 74. Just as importantly, a single failure never takes down the whole building. Most units are built to a standard 42-inch width, which means a replacement chassis usually slides straight into the sleeve that is already in your wall.

PTAC Installation & Replacement in Charleston, WV

Every PTAC installation we do starts with confirming what is actually in your wall. If the existing sleeve is structurally sound, we can typically replace the chassis without touching drywall or exterior masonry — a job measured in minutes rather than days. If the sleeve is rusted through, which is common in units that have been draining improperly for years, we replace it and reseal the opening correctly. A poorly flashed sleeve is one of the most common sources of water damage and cold drafts we find in older Charleston buildings, and covering it up with a new unit only hides the problem.

We also verify your electrical configuration before ordering equipment. Most PTACs run on 208/230-volt circuits, while many commercial buildings are wired for 265/277 volts, and the chassis, power cord, and subbase all have to match. A voltage mismatch is one of the more expensive mistakes we get called in to correct after a do-it-yourself replacement.

Getting the Size Right

An oversized PTAC cools a room quickly and then shuts off before it has pulled any real moisture out of the air. In a West Virginia July, that leaves you with a room that reads 70 degrees on the thermostat and still feels clammy. Undersized units run nearly nonstop and burn out compressors years early. We size to the room rather than to whatever happened to be installed before:

• 250–300 sq. ft. — 7,000 BTU
• 300–400 sq. ft. — 9,000 BTU
• 400–550 sq. ft. — 12,000 BTU
• 550–700 sq. ft. — 15,000 BTU
• 700–1,000 sq. ft. — 17,000 BTU

These are starting points, not final answers. Ceiling height, window area, sun exposure, insulation levels, and typical occupancy all shift the calculation. A west-facing corner room with two large windows needs more capacity than its square footage suggests, while an interior room on a shaded north wall needs less.

Heat Pump or Electric Resistance Heat?

PTACs come in two heating configurations, and the difference shows up on every utility bill. A standard PTAC heats with electric resistance elements — simple, reliable, inexpensive to install, and costly to run. A packaged terminal heat pump, or PTHP, reverses the refrigeration cycle to move heat indoors instead of generating it, which uses considerably less electricity. When outdoor temperatures fall below roughly 35 degrees, a PTHP falls back on electric resistance elements to keep up.

For most Charleston properties, a PTHP earns back its higher purchase price through lower operating costs, especially in buildings where the owner pays the utility bill and the heating season runs from October through April. If you only need occasional heat, or you are conditioning a space that sits empty for much of the winter, standard electric heat may be the better value. We will run the comparison for your building and your rate structure rather than pushing you toward whichever unit is easier for us to stock.

PTAC Repair in Charleston, WV

Most PTAC complaints trace back to maintenance rather than mechanical failure. Clogged filters, coils packed with dust and lint, and blocked drain pans account for the majority of the "this room will not cool" calls we take. Our technicians diagnose the actual cause instead of guessing at it, and they carry common parts on the truck so a single visit usually ends the problem. Here is what we see most often:

• Not cooling or not heating — refrigerant loss, a failed compressor, a stuck reversing valve, or a tripped thermal overload
• Water leaking into the room — a clogged drain pan, an obstructed condensate path, or a sleeve pitched the wrong direction
• Rattling, buzzing, or grinding — worn blower bearings, a loose fan wheel, or debris that has worked its way into the sleeve
• Short cycling or drifting temperatures — dirty coils, a failing thermostat sensor, or a chassis that was oversized for the room
• Musty or stale odors — a saturated filter and biological growth on the evaporator coil
• Tripped breakers or intermittent operation — corroded terminals, weak supply voltage, or a failing capacitor
• Unresponsive controls — a failed control board or a wall thermostat that has lost communication with the unit

When a chassis is genuinely past economical repair, we will tell you so plainly and price the replacement instead of selling you a repair that buys six months. And when a unit quits at midnight on a holiday weekend, our 24/7 emergency service covers Charleston and every surrounding community we serve.

PTAC Maintenance for Hotels, Apartments & Care Facilities

A PTAC that is serviced on a schedule commonly lasts 12 to 15 years. One that is neglected often fails somewhere between year seven and year ten, and sooner still in a hotel where units run close to year-round. Across a sixty-room property, that gap is a capital expense you absorb half a decade earlier than you needed to — plus every night of lost revenue along the way.

Our PTAC maintenance visits cover:

• Cleaning or replacing filters
• Washing evaporator and condenser coils
• Clearing drain pans and condensate paths
• Checking refrigerant charge and testing for leaks
• Inspecting and tightening electrical connections
• Testing capacitors, contactors, and compressor amp draw
• Verifying thermostat calibration and control operation
• Lubricating motors and checking blower wheel balance
• Inspecting sleeve seals, wall flashing, and exterior grilles

We schedule building-wide service around your occupancy, work floor by floor during your slow season, and leave you with a written report showing which units are trending toward replacement. That turns equipment failure into a line item you can budget for instead of an emergency you react to. Ask us about Comfort Plan Maintenance Memberships for recurring, prioritized service.

PTACs for Homes: Additions, Sunrooms & In-Law Suites

PTACs are not only for commercial buildings. If you have added a sunroom, finished a garage, converted an attic, or built an in-law suite, extending your existing ductwork into that space is often expensive and rarely effective. The new room ends up starved for air while the rest of the house overcools, and your central system works harder for a worse result. A PTAC gives that space its own heating and cooling on its own thermostat without touching the system that serves the rest of your home.

That said, for most Charleston homes we will also walk you through ductless mini-splits before you decide. Here is how the two compare:

For a living space you use every day, a ductless mini-split is usually worth the additional investment. For a workshop, a rental unit, a garage apartment, or a wall that already has a sleeve in it, a PTAC is often the smarter spend. We will give you an honest comparison for your situation instead of steering you toward one.

Frequently Asked Questions About PTAC Units

How long do PTAC units last?

With consistent maintenance, a PTAC typically lasts 12 to 15 years. Without it, most units fail between year seven and year ten, and hotel units running nearly year-round can fall at the shorter end of that range. Filters, coils, and drain pans are what separate the two outcomes. If your units are past year ten and have never been on a service schedule, we can inspect the fleet and tell you which ones are worth maintaining and which are living on borrowed time.

Can you replace just the PTAC chassis, or do I need a new wall sleeve?

In most cases the sleeve stays and only the chassis is replaced. Because nearly all PTACs are built to a standard 42-inch width, a new unit slides into your existing sleeve, which keeps the job fast and avoids any work on your drywall or exterior wall. We do replace the sleeve when it has rusted through, lost its pitch, or was never sealed properly to begin with — all of which we check before quoting the job so there are no surprises mid-installation.

Do I need a permit to replace a PTAC in Charleston, WV?

It depends on the scope. A like-for-like chassis replacement in an existing sleeve often does not require one, while cutting a new wall opening, adding or modifying circuits, or changing equipment type typically does. The City of Charleston and Kanawha County set those requirements, and they can differ for commercial and multi-family buildings. We will tell you upfront which category your project falls into, and when a permit is needed we handle the filing and inspection coordination for you.

How often should PTAC units be serviced?

We recommend professional service at least twice a year for commercial properties — once before cooling season and once before heating season — with filter checks quarterly or more often in high-occupancy buildings. Residential PTACs in a sunroom or addition generally do well with one annual visit. In hospitality settings, units that have gone more than 90 days without attention are the ones that generate guest complaints, which is why we build maintenance schedules around your occupancy calendar.

Should I install a PTAC or a ductless mini-split in my addition?

If it is a room you will live in daily — a family room, a bedroom, a home office — a ductless mini-split is usually the better investment. It is quieter because the compressor sits outside, it is meaningfully more efficient, and it looks better inside and out. A PTAC makes more sense when upfront cost is the deciding factor, when there is already a sleeve in the wall, or for a garage, shop, or rental space where compressor noise is not an issue. We install both and will give you a straight comparison for your specific room.
