Matthew found that the upstairs condenser was not running and had no power, and the breaker was off. He cut the unit back on, then did amp draws on the compressor and the fan motor. He also checked for electrical shorts and found no cut or burnt wires.
The upstairs unit ran just fine after being cut back on, with the compressor and fan motor amp draws all within range.
We have been long-term customers of Coastal Eco Heating & Air for many years and across several properties, and we have the highest opinion of their service. They are incredibly reliable and trustworthy, and we can always count on them to be there when we need them—even during the busiest times. They have rescued us with timely service on multiple occasions. Highly recommend!

Even if your HVAC seemed fine after flooding, water damage shows up years later through corroded connections, contaminated ductwork, and weakened compressors. Here's what Friendswood and Galveston homeowners need to know.

Salt air, extreme humidity, and storm exposure shorten HVAC lifespans by 3-5 years on the Gulf Coast. Here's what Galveston homeowners can do to fight back.
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.
More ways we can help in Friendswood.
Answered by our licensed technicians serving Friendswood.
We recommend bi-annual maintenance for Friendswood homes: AC tune-up in March-April before our long cooling season, and heating check in October-November. Homes in flood-prone areas near Clear Creek should also schedule a duct inspection annually, as moisture intrusion can lead to hidden mold growth in ductwork.
Our Friendswood HVAC tune-up includes refrigerant check, coil cleaning, condensate drain flush (critical in our humidity), electrical inspection, thermostat calibration, and filter replacement. We also check for duct leaks, common in Friendswood homes built in the 1970s-80s where ductwork tape has deteriorated.
Yes. Friendswood's proximity to grasslands and the coast means high pollen and mold spore counts. Regular HVAC maintenance including filter changes, coil cleaning, and duct inspection significantly reduces indoor allergens. We also offer UV light systems and air purifiers designed for Gulf Coast air quality challenges.
