"July 2017 OAT +101 (F) -one of my AC units stopped working. I called them at 3:30 P.M. Wed. and they tried to to help me that same day , but of course, with the temps in the 100's they were very busy with other emergencies. They got to me first thing the next day and had my A/C up and running within a few hours. Great service! Great communication! I would definitely recommend them. They will do all my future HVAC work."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"We have a water system on our place for cleaning and treating our water since we have wells. We have a water clarification system which we bought from them and they come out every year and do maintenance on it. It is more than just a softener, it's a clarification system as well, it crops out solids and everything. They've got a service tech that's really knowledgeable and knows his business. Their maintenance costs and service calls are not inexpensive but they are no different from anybody else. When they came to install the new part, it took about 20 or 30 minutes."

"I've had Aire Serve for a number of years and I'm very happy with it. I've now switched over to another provider so I no longer have to worry about the other type, the freon or anything. I've had no problems with them; I've had them for years. Their price was competitive in San Antonio. I don't know what other prices are. I just know that I was happy with what I got. They're a really good company and I've had them for probably ten years. I'm not one to switch around companies and never know what you're gonna get from them."

"Prompt, knowledgeable, and efficient!!! I was impressed that Legend Plumbing responded quickly to my water line repair. Their plumber arrives ahead of time and handles the service directly. It was only a short period that he was able to finish the job, and I was glad that the water line repair was done effectively. A truly dependable service."

"Everything went smoothly up until I had a ceiling leak and we found that the condensation line to the other unit was broken during the installation. It was not carelessness but a poor design by the builder of the home. Anyway, they agreed to fix it and the damage it caused, without any need for me to make a lot of noise. My only complaint was that the repair was long and drawn out taking 4 or 5 visits to complete and the repairman was good but never came on schedule."

FAQs for swamp cooler service or repair projects in Lockhart, TX

A well-maintained swamp cooler can last between 10 and 15 years. Its longevity depends on usage frequency, water quality, and proper care. Regular maintenance, like winterization and protective measures, can preserve your system's efficiency and prevent premature breakdowns, ensuring reliable cooling performance over its lifespan. Hiring a professional to take care of any repairs over your swamp cooler’s lifespan will ensure it’s restored to proper functioning and can help it last longer.

You should consider replacing your swamp cooler if it shows signs of severe corrosion, inadequate maintenance, advanced age, restricted airflow, or ongoing leaks. When repair costs and performance inefficiencies make restoration impractical, replacement may be the best option. Evaluating these issues with a professional ensures you choose the most effective solution, preserving comfort and cost efficiency while avoiding further deterioration of the system.
