Air Conditioning Services In Alamo Heights
The AC in an Alamo Heights home runs from April into October. When it stops keeping up, we find the cause before we quote a fix.
- AC repair: warm air, short cycling, leaks, frozen coils, strange noises and systems that won’t turn on. We repair before we ever recommend replacement.
- AC replacement and installation: when an older system keeps breaking down, we size new equipment to your home’s layout and walk you through repair versus replacement with real numbers. Financing is available.
- AC maintenance: a spring tune-up finds worn parts while they’re still a small repair. A membership plan keeps you on schedule with priority service.
- Heat pumps, air duct cleaning and indoor air quality: for hot rooms, weak airflow, dust and stale air that a working AC alone doesn’t fix.
What Goes Wrong In Older Alamo Heights Homes?
Alamo Heights was incorporated in 1922, and much of its housing was built before World War II. Plenty of those homes still run on systems that were added decades after the house went up.
- Ductwork: central air was often added to these homes later, which can mean undersized returns, long duct runs through hot attics and leaks at old connections. That shows up as rooms that never cool evenly. We check duct sealing and insulation as part of the diagnosis.
- Plumbing: original galvanized supply lines and cast iron drains are common in older homes. Low water pressure, rusty water and slow drains are often signs the pipes are reaching the end of their life, and whole home repiping may be the lasting fix.
- Sewer lines: the mature oaks that line Alamo Heights streets send roots toward older sewer laterals. A sewer camera inspection shows exactly where the problem is before anyone digs.
Heating Services In Alamo Heights
Heaters here can sit idle from March to November, then fail on the first cold night. We handle heater repair, seasonal heater maintenance and furnace replacement, and because we service both heating and cooling, one company covers your system all year.
Plumbing And Drain Services In Alamo Heights
- Water heaters and tankless water heaters: repair, replacement and new installs.
- Leak detection and slab leak repair: we find hidden leaks before they damage floors and foundations.
- Drain cleaning, hydrojetting and sewer line services: from a slow sink to a main line clog.
- Gas line service: safe repairs and new lines for gas appliances and water heaters.
- Water softeners and filtration: Alamo Heights runs its own water system, pumping from six Edwards Aquifer wells. Edwards water is naturally hard, and those minerals build up as scale in water heaters and on fixtures. A softener protects both.
Recent Work In Alamo Heights
Our technicians work in homes across Alamo Heights (78209) every month. A few examples of what that work looks like:
- Plumbing tests for foundation repair. Homes in the area move on expansive clay soil, and foundation repair is common. We run hydrostatic tests before and after foundation work, so hidden leaks under the slab get found and fixed while the work is underway.
- Sewer camera inspections ahead of foundation repair, to check the line before the house was lifted.
- Leak repairs and drain clearing, from slow kitchen sinks to main line clogs.
- AC repair and tune-ups, including systems that couldn’t keep up on the hottest afternoons.
How Does Clay Soil Cause Slab Leaks?
Alamo Heights homes sit on clay that swells when it’s wet and shrinks in a drought. The slab moves with the soil, and pipes under the slab can crack or pull apart at the joints. Foundation repair moves the slab again, which is why we test the plumbing both before and after the lift.
