Q&A
My San Angelo AC keeps turning on and off quickly (short cycling). What's causing this and how can ER Heating And Air fix it?
Short cycling is often caused by an oversized unit, a dirty air filter, low refrigerant, or a faulty thermostat—all issues exacerbated by our intense Texas heat. Our technicians will perform a comprehensive diagnostic to pinpoint the exact cause. We then provide the necessary repair, whether it's sealing refrigerant leaks, cleaning coils, calibrating your thermostat, or advising on proper system sizing, to restore normal, efficient operation and prevent wear on your compressor.
Why is my outdoor AC unit in San Angelo overheating, and how do you prevent compressor failure?
Overheating compressors here are frequently due to lack of maintenance, dirty condenser coils restricting airflow, or refrigerant problems. The high ambient temperatures strain the system further. ER Heating And Air prevents this with proactive maintenance, including thorough coil cleaning, checking refrigerant levels, ensuring proper electrical connections, and clearing debris around the unit. This service maximizes airflow and efficiency, directly combating the local conditions that lead to premature system failure.
What specific HVAC maintenance do you recommend for San Angelo homes to prevent these common issues?
We recommend bi-annual maintenance, especially before summer and winter. Our tailored service includes cleaning evaporator and condenser coils, checking refrigerant charge, inspecting electrical components, testing the thermostat, and ensuring proper airflow—all critical steps to prevent short cycling and overheating. This proactive care is the best defense against our extreme weather, improving reliability, efficiency, and helping you avoid costly emergency repairs during peak seasons.
