Blowing room-temperature air
Dirty coils, a fan motor or a compressor fault.
Commercial in Grand Rapids, MI
PTAC and through-the-wall unit service in Grand Rapids
Packaged terminal units heat and cool one room each, in apartments, hotels, senior housing and offices. We repair them, replace them unit by unit and keep the sleeves weathertight.
The short answer
PTAC service in Grand Rapids covers the self-contained heating and cooling units that sit in a wall sleeve under a window in apartments, hotel rooms and offices. Most failures are a dirty coil, a failed fan motor, a control board or a heat strip, and most are repaired in one visit. Replacements slide into the existing sleeve when the size matches.
What you might notice
Signs a PTAC needs service
Water on the floor
Blocked drain or sleeve tilt.
Rattling or buzzing
Loose panels, fan blade or failing motor.
Tripping breakers
A shorted heater or compressor.
Drafts around the unit
Worn sleeve gaskets and caulking.
One room, one unit
How PTAC units fail
A PTAC holds a compressor, two coils, fans, a heat strip or heat pump and the controls in one chassis that slides into a sleeve through the outside wall. Because each unit serves one room and runs hard, dust, lint and outdoor debris build up quickly, and the failures repeat across a building.
Buildings with many units benefit from scheduled filter and coil cleaning through commercial maintenance. Rooftop and split equipment is covered under commercial HVAC repair in Grand Rapids.
The jobs we do
PTAC repair
The most common PTAC complaints are no cooling, no heat, noise and water on the floor. No cooling usually traces to a dirty outdoor coil, a failed fan motor or a compressor that will not start. No heat points to a failed heat strip, a tripped thermal limit or, on heat pump models, a reversing valve or defrost fault. We test the chassis on the bench or in the sleeve, clean both coils while it is out, and replace the failed part so the unit goes back into service the same visit where the part is available.
PTAC replacement
When a chassis is old or the compressor has failed, replacing the whole chassis is usually cheaper than a major repair. Most modern PTACs use a standard sleeve size, so a new chassis slides into the existing sleeve with a new outdoor grille where needed. We confirm the voltage, amperage and plug type match the existing receptacle, since a mismatch is the most common replacement mistake, and we can replace units in stages so a building is never without heat in too many rooms at once.
Through-the-wall AC and heat units
Through-the-wall units look similar to PTACs but are usually cooling units with limited or no heat, often in older apartments, additions and offices. They fail the same ways, and they also leak air and water around the sleeve when the caulking and gaskets age. We service the unit, reseal the sleeve inside and out, and check that it drains to the outside. Where a room needs real heat and cooling, we explain whether a PTAC or a ductless head would serve it better.
From the call to a working system
How a PTAC call runs
Identify the unit
Model, voltage and symptoms recorded for each room.
Test the chassis
Unit tested in place or pulled for bench diagnosis.
Clean and repair
Coils cleaned; failed part replaced.
Replace where needed
New chassis matched to sleeve and receptacle.
Seal and test
Sleeve sealed, drainage checked, heat and cooling run.
Timing
How long rooms are affected
Most single-unit repairs are finished in one visit, and a replacement chassis that matches the sleeve goes in the same day.
Building-wide replacements are scheduled in stages so only a few rooms are out of service at a time.
Local conditions
Apartments and older buildings
Grand Rapids has a large stock of apartment buildings, senior housing and older commercial buildings where each room has its own through-the-wall unit rather than central air. In a long heating season, heat strips and heat pump PTACs carry a lot of load, and the outdoor side of every sleeve takes snow and wind, so gaskets and drains need checking as often as the units themselves.

Pricing, explained
What PTAC work costs depends on
PTAC repairs are priced per unit after testing; replacements depend on the chassis model and whether the sleeve and grille can be reused. Multi-unit work is quoted as a group.
Repair or replace
A fan motor or board versus a whole new chassis.
Heat type
Heat strip and heat pump models differ in price.
Sleeve fit
Reusing the sleeve and grille keeps replacement simpler.
Electrical match
Voltage, amperage and plug type must match the receptacle.
Number of units
Building-wide work is scheduled and priced as a group.
