Adrian
September 2026
A Friendswood homeowner with four HVAC units called about a possible leak.
Adrian cleared the drainline for all 4 units and checked the charge and heat kit of every unit. He found that 2 heat kits needed 2 pole contactors: one wasn't working and the other was buzzing really loud. Adrian replaced the 2 pole contactors on those two heat kits during the visit.

A Friendswood homeowner reported that their AC was not cooling.
Adrian found that the condenser was getting tripped and not running properly, with lots of loud noises coming from the condenser. He re-wired the furnace to stop it from short cycling the condenser. He also had to cut out the float switch because it was randomly cutting off the unit.
After the rewiring, the furnace was no longer short cycling the condenser.
Brandon
May 2026
At a rental home in Friendswood, Brandon found the outdoor unit power reading 120v on one leg and 64v on the opposite leg, with nothing across, and the unit had been taken apart inside and out by the tenant with configurations inappropriately adjusted. He replaced the condenser breaker to restore proper power supply to the outdoor unit. Brandon then reset all settings, configurations, and programming back to factory defaults and power cycled the unit.
Operation was restored, and Brandon set the thermostat at 74°.

When the Texas heat index climbs past 105°F, your AC may run almost nonstop, and that might be perfectly normal. Here's how to tell the difference between a hardworking system and one that needs repair.
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.
