Why Richwood Homes Are Different
Richwood sits in the Brazos River delta floodplain, roughly 15 miles from the Gulf of Mexico and the Freeport-area Dow Chemical corridor. Hurricane Harvey in 2017 flooded a significant share of the housing stock, which means we regularly encounter two very different systems on the same street: post-2017 replacements installed at elevated heights to meet updated Brazoria County floodplain requirements, and older surviving units that took on moisture and never fully recovered.
The salt air carried inland by the onshore Gulf breeze corrodes aluminum condenser fins and copper refrigerant lines within three to five years without protective coil coating. From May through September, sustained dewpoints in the mid-70s°F create a latent load that overwhelms slightly undersized or low-charge units. We also find air handlers relocated to attics during post-flood remediation without proper condensate trap re-engineering, causing chronic drain overflow that gets misdiagnosed as a refrigerant leak. The housing stock itself, largely modest single-family homes built from the 1960s through the 1990s for petrochemical workers, often has older duct chases mismatched to newer equipment sizing, which underperforms on humidity control even when the temperature drops.
Our Main Richwood Services
Richwood homeowners call us most often for emergency cooling repairs in summer and furnace failures during Gulf Coast cold snaps. Each service has its own dedicated Richwood page with full details.
AC Repair in Richwood
AC repair in Richwood means dealing with salt-corroded contactors, refrigerant leaks at finned-tube joints, and condensate drain failures from improperly re-piped air handlers. We carry capacitors, contactors, and refrigerant for Goodman, Rheem, and York systems on every truck, and we test both temperature split and humidity removal because the Gulf moisture load here is extreme. Most repairs run $150-$650. AC Repair in Richwood covers common failures, response times, and what our 365-Day Done Right Promise means for your cooling system.

Furnace Repair in Richwood
Richwood furnace repair often involves igniter failures on post-Harvey replacements, heat exchanger inspections on older surviving units, and thermostat wiring compromised by attic moisture. Gas pressure testing is critical here because floodplain elevation changes affect manifold pressure settings on newer installations. We repair gas furnaces and heat pumps, and we keep igniters, flame sensors, and control boards in stock for same-day fixes when possible. Furnace Repair in Richwood explains our process and pricing.

AC Installation in Richwood
AC installation in Richwood requires load calculations that account for the latent load from Gulf moisture, proper elevation for floodplain compliance, and ductwork evaluation to ensure older chases can handle modern airflow requirements. We size for dehumidification, not just temperature drop, and we handle rebate paperwork for qualifying high-efficiency systems. Every installation gets a written fixed price before work begins and a scheduled install date. AC Installation in Richwood covers equipment options and financing.

What Richwood Customers Say
"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."
- Celeste Ngo"The repair was done well and quickly. Scheduling over the phone was a little clunky and I got transferred twice, but the tech himself was great and on time."
- Brett Haygood"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
- Russ Tiedemann
