HVAC Company in Manor, TX
Most HVAC calls we get in Manor involve 5- to 15-year-old builder-grade systems that weren’t sized for the full heat load on flat, treeless Blackland Prairie lots. Homeowners in subdivisions like Shadowglen often tell us their unit is “running but not cooling” – a pattern we trace back to undersized equipment, cramped attic ductwork, and 140°F attic temperatures in July. Coldharbour Heating & Air dispatches technicians from our Austin office to serve Manor locally, and we carry the Kingswell Guarantee on every job: a written price before work starts, a firm arrival window, and our 365-Day Done Right Promise. Call (817) 402-2972 when you need us.
Why Manor Homes Are Different
Manor’s housing stock is dominated by post-2010 master-planned construction – slab-on-grade foundations, open floor plans with high ceilings, and attic-ducted split systems that production builders installed to minimum code, often 14 SEER efficiency ratings. These systems were engineered for a price point, not for the sustained heat exposure that comes with sitting on the eastern edge of Travis County where the Hill Country’s modest cooling effect disappears entirely.
The Blackland Prairie clay beneath these homes expands and contracts dramatically with seasonal moisture changes. We’ve found condenser pads tilted and slab penetrations shifted enough to stress refrigerant line sets and crack drain lines – a maintenance issue you don’t see as often in the rockier soils west of Austin. In the newer subdivisions, attic-installed air handlers bake in unconditioned spaces that hit 140-150°F in peak summer. Combined with undersized ductwork and high static pressure, that heat gain into the supply plenum means the system runs continuously without ever hitting the thermostat setpoint. It’s a mechanical problem that looks like a refrigerant problem until you measure airflow and duct temperature.
Our Main Manor Services
Manor homeowners call us most often for cooling repairs in summer and heating repairs during the brief but sharp cold snaps that roll across the prairie. Each service has its own dedicated Manor page with deeper detail.
AC Repair in Manor
AC repair in Manor typically starts with a homeowner describing a system that runs constantly or blows warm air. We check refrigerant levels first, but we also measure static pressure across the evaporator coil because we’ve learned that restricted airflow from undersized ductwork mimics a low-charge condition in this market. Our technicians carry common capacitors, contactors, and refrigerant to complete most repairs in a single visit. Every repair comes with our written 365-Day Done Right Promise. AC Repair in Manor

Furnace Repair in Manor
Furnace repair in Manor means working on gas furnaces in attics and closet installations, often with short vent runs and limited combustion air access. Igniter failures, limit switch trips, and flame sensor corrosion are the usual culprits when a furnace won’t fire on the first cold night. We test heat exchangers with visual inspection and combustion analysis on every furnace call – no exceptions. If we find a crack, we show you before we discuss options. Furnace Repair in Manor

AC Installation in Manor
AC installation in Manor requires a proper Manual J load calculation because the original builder specs routinely undersized these systems relative to actual demand. We measure the home, account for the flat-lot sun exposure and high ceilings, and specify equipment that can handle the load without running at maximum capacity all day. Our installation quotes include a written fixed price, a scheduled install date, and we handle rebate and financing paperwork. AC Installation in Manor

Most master-planned communities in Manor require HOA architectural approval for outdoor unit changes, and the city requires permits for full system replacements. We pull the mechanical permit and provide the documentation your HOA needs as part of our installation process.
Manor’s rapid build-out meant many homes received minimum-spec HVAC systems on flat, unshaded lots with intense sun exposure. The equipment was sized to pass inspection, not to handle peak loads comfortably, which is why we find so many systems struggling at year five to ten.

What Manor Customers Say
"Honest to a fault. Two companies told me I needed a whole new unit. Coldharbour said mine had years left and just needed a cleaning and a part. Saved me thousands."
- Marcus Reilly"Furnace wouldn't light the first cold morning. The guy walked me through what he was checking so I actually understood it. Replaced the igniter, wrote up the warranty, and it's been warm since."
- Alicia Romero"AC died overnight with a newborn in the house. They bumped us up the list and had it running by noon. I about hugged the guy. Fair price even on a rush call."
