October 2026 in review: we completed 77 jobs for customers around Galveston Bay, and diagnostic and repair calls made up most of the work. Here is what the month showed us and what to watch next.
Read articleFriendswood's persistent humidity, often above 80%, forces HVAC systems to work overtime removing moisture. Standard cooling alone can't maintain comfortable indoor humidity, making properly sized equipment and supplemental dehumidification important.
Friendswood experienced severe flooding during Hurricane Harvey and other storm events. Homes that have flooded may have contaminated ductwork, corroded components, or water-damaged insulation that affects HVAC safety and performance.
Friendswood's blend of 1970s-80s established neighborhoods and newer developments like West Ranch means HVAC needs vary widely, from full system modernization in older homes to efficiency optimization in newer construction.
Friendswood's cooling season runs roughly April through October, with AC running nearly continuously during peak summer. This 7-month demand puts significant wear on equipment and drives high energy bills without proper maintenance and sizing.

Salt corrosion on condenser coils can reduce heat transfer enough that your system runs continuously without reaching set temperature, even with a full refrigerant charge. If the aluminum fins are pitted, caked with salt deposits, or crumbling, the coil can't reject heat efficiently regardless of refrigerant level.
We use three methods: electronic leak detectors that pick up very small leaks, nitrogen pressure testing to isolate which section is compromised, and UV dye injection for leaks that are hard to pinpoint. Coastal pinhole leaks are hard to find, so we use whichever combination the system calls for.
No. Adding refrigerant without fixing the leak is like putting air in a tire with a nail. On the coast, the salt corrosion that caused the first leak is actively creating new ones. You'll need another recharge in weeks or months, at $50-$150/lb for R-410A or $150-$300/lb for R-22.
R-22 is phased out and increasingly expensive. If your system needs refrigerant more than once per season, replacement with a new system is usually the better investment. Two R-22 recharges can cost $1,500-$6,000, money that goes further toward new equipment.
Isolated leaks can be brazed with silver solder and coated. But on coastal systems over 7-8 years old, we often find multiple corroded areas. Repairing three spots only to have new leaks open in six months isn't cost-effective. Full line replacement with corrosion-protected tubing is the smarter investment.
