“Our Air conditioner stopped working the day before a huge party on the hottest day. Josh came out first thing in the morning and installed the part. We joined their HVAC plumbing maintenance and they came back and maintenance the HVAC and then the plumbing guy came and flushed the water heater and did maintenance as well as check flow of house water. The are great people friendly polite and fairly priced. There is great follow up and quick response to questions. Best customer service I have encountered in a long time. It is a forgotten art.”

What customers say about AC Repair
AC repair questions we hear most
Find answers to common plumbing and HVAC questions from our expert team.
This is one of the most common calls we get during a Central Texas summer. The cause is usually one of a few things: low refrigerant from a leak, a dirty or clogged condenser coil, a failing compressor, or a frozen evaporator coil. Each of these requires professional diagnosis with proper gauges and equipment. We'll pinpoint the problem and give you an honest repair-vs-replace recommendation.
We recommend checking your filter every 30 days and replacing it at least every 60-90 days, or more frequently if you have pets, allergies, or live in a dusty area. A clogged filter restricts airflow, makes your system work harder, increases energy bills, and can lead to frozen coils and compressor damage. It's the single easiest thing you can do to prevent costly AC repairs.
Different sounds point to different issues. A grinding or screeching noise usually means a motor bearing is failing. A clicking sound at startup could be a relay problem. A hissing or bubbling sound often indicates a refrigerant leak. A banging noise can mean a loose or broken component inside the compressor. Any unusual sound should be checked promptly to prevent a small repair from turning into a major one.
As a general rule, if your AC is over 10-12 years old and the repair cost is more than half the price of a new system, replacement is usually the better investment. Newer systems are significantly more efficient—upgrading from a 10 SEER unit to a 16 SEER can cut your cooling costs by nearly 40%. We'll always give you both options with transparent pricing so you can make the best decision.
Yes. We understand that losing AC in a Texas summer isn't just uncomfortable—it can be dangerous, especially for children and the elderly. We offer priority emergency service and aim to respond as quickly as possible. Our trucks are stocked with the most common parts so we can complete most repairs on the first visit.
