Do you handle both residential and commercial HVAC?
Yes. The company specializes in residential and light commercial heating and air conditioning: repairs, maintenance, installations, and rooftop unit support.
Why is my AC not cooling in Texas heat?
Common causes include failed capacitors, dirty filters or coils, clogged condensate drains, low refrigerant, weak airflow, and aging outdoor equipment struggling in extreme attic and outdoor temperatures. A proper diagnosis finds the root cause instead of masking symptoms.
How much does AC repair cost?
Repair costs vary widely based on the part and the complexity of the job. Rainwater Mechanical focuses on honest options and will present a repair path when it makes sense, without defaulting to an unnecessary system replacement pitch.
How long does a typical repair take?
Some repairs take minutes; others take longer depending on access, parts, and system condition. Technicians aim to be efficient and thorough while respecting your schedule.
Do repairs come with a warranty?
Yes. Work completed by Rainwater Mechanical is backed by a warranty on the repair so you can have confidence in the fix.
