Call (817) 402-2972

We’re Coldharbour Heating & Air, and we’ve spent two decades working on the exact systems found in Aldine’s 1960s-1980s slab-on-grade ranch homes. The name comes from old roadside shelters where travelers waited out rough weather. That’s still the job: keeping Aldine comfortable when the Gulf Coast heat pushes attic temperatures past 140°F and your compressor is fighting for its life. Our phones are answered by a live person 24 hours a day, 7 days a week. Call (817) 402-2972.

Why Coldharbour Heating & Air Is Aldine’s Preferred AC Repair Company

Aldine sits in a tricky spot, jurisdictionally speaking. Because it’s unincorporated Harris County rather than Houston proper, every AC repair that turns into a replacement needs a county permit pulled under county codes, not Houston city registration. Plenty of contractors working both markets get this wrong. We don’t. Our AC Repair team knows the difference and handles the paperwork so you don’t get stuck with a failed inspection.

Our technicians are background-checked, uniformed, and trained on nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We carry common parts for Goodman and Rheem units, which dominate Aldine’s rental stock, so most repairs finish in a single visit.

Every job follows The Kingswell Way: we say the price before the work starts, show up in the window we promised, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. The 365-Day Done Right Promise means if your repair quits within a full year, we return and correct it at no charge. That guarantee is written down before our technician leaves your driveway.

We know the roads. Aldine Mail Route, Eastex Freeway corridor, the greensheet neighborhoods tucked between them. That local knowledge means we don’t waste time getting lost or guessing which attic access you’re working with.

AC Not Blowing Cold Air in Aldine

AC Not Blowing Cold Air is the call we get most often in Aldine from June through September, when systems that were barely keeping up finally surrender. In this market, the problem usually traces to one of four causes: a failed capacitor (the electrical component that jump-starts your compressor and fan), a refrigerant leak (often in the evaporator coil or line set), a seized condenser fan motor, or collapsed flex duct in a 140°F attic that’s choking airflow before it ever reaches your vents. Most diagnostic and repair visits run $150-$650.

What Our Technician Checks First

We start with static pressure and temperature split measurements across the evaporator coil. If the numbers don’t match the manufacturer’s specs for your Goodman, Trane, or Lennox unit, we work backward: refrigerant charge, blower speed, then duct integrity. No guesswork. The written diagnosis comes before any repair recommendation.

When Short-Cycling Masks as “Not Cold Enough”

A compressor that starts and stops every few minutes never runs long enough to pull humidity from the air. In Aldine’s heavy latent-load climate, that leaves you clammy at 78°F. We see this constantly in post-Uri replacement systems that were never commissioned correctly. The fix is usually refrigerant recovery and precise weighing, not a bigger unit.

AC Maintenance in Aldine

AC Maintenance in Aldine isn’t a luxury for a system that runs 9-10 months a year under Gulf Coast humidity. It’s how you avoid the emergency call that costs three times as much in July. Our tune-up visits run $80-$200 and include a written report of everything we find, with photos. Our technicians are not paid on what they sell, so the recommendation you get is the one your system actually needs.

What We Address in Aldine’s Attics

We inspect flex duct for collapse and seal degradation, check condensate drains for algae blockage (common in our humidity), and measure superheat and subcooling on the refrigerant side. Attic temperatures here routinely exceed 140°F in peak summer, so we pay special attention to capacitor tolerance and contactor pitting that accelerates in heat.

The Post-Uri Recommissioning Check

After Winter Storm Uri in February 2021, many Aldine homes got replacement systems installed in the chaotic post-freeze rush. Three to four years later, we’re finding mismatched condensers and evaporator coils, incorrect refrigerant charges, and heat pump lockouts that were never reset. Our maintenance visit catches these commissioning errors before they turn into compressor failures.

Trusted Brands We Service in Aldine

Our technicians carry diagnostic training and common parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Aldine specifically, Goodman and Rheem units appear most frequently in the rental stock north of Aldine Mail Route, and we keep capacitors, contactors, and fan motors on the truck for same-day resolution. Trane and Lennox systems dominate the owner-occupied pockets closer to the Eastex Freeway corridor. Whatever’s in your home, the technician who shows up can work on it without a return trip for “specialty training.”

Common AC Repair Problems We See in Aldine Homes

• Collapsed flex duct in 140°F attics. The original or first-replacement flex duct in Aldine’s 1960s-1980s stock was rarely sized or sealed properly. After decades in unconditioned attics that hit 140°F in July, it collapses, splits at seams, or pulls loose from boots. The compressor runs and runs, but cooled air never reaches the rooms.
• Mismatched post-Uri replacement systems. Systems swapped in the February 2021 freeze recovery often paired new condensers with old evaporator coils, or spec’d line sets to wrong tonnages. Three to four years later, these Frankenstein setups short-cycle, freeze up, or fail to hold setpoint in Aldine’s humidity.
• Oversized units spec’d for peak BTU, not moisture removal. An 1,800 sq ft slab home doesn’t need a 4-ton monster, but that’s what some installers sell. The unit blasts cold air in five minutes, shuts off, and never runs long enough to wring humidity from the air. You feel damp at 78°F because you are damp.
• R-22 equipment with rising recharge costs. Many Aldine rentals still run original or first-replacement R-22 condensers. With R-22 phased out, a refrigerant recharge runs hundreds of dollars for a declining supply. At some point, the repair-or-replace math tips hard toward replacement, especially when the condenser coil is already leaking.
