At Gatewood HVAC, we know AC troubles hit hard in Sonora’s desert climate. When your system acts up during hot summer days, you need fast, smart solutions. Here are the most frequent issues we see and how to fix them efficiently.
1. Not Blowing Cold Air
Your AC may be running, but if the airflow feels warm, check your thermostat settings first. If settings are correct, a dirty filter, low refrigerant, or dirty coils could be the culprit. Replace the filter and clean the coils. If the problem persists, call us to check refrigerant levels and inspect for leaks.
2. Weak Airflow
Muffled or low airflow often comes from a clogged filter or blocked ductwork. Start by replacing or cleaning the filter. Then check vents and returns — dust, furniture, or debris might be blocking airflow. If airflow remains weak after that, we’ll check your blower motor and duct layout.
3. Frequent Cycling On and Off
Short cycling, when the system turns on and off too often, can cause uneven cooling and premature wear. It’s often caused by an oversized unit, thermostat issues, or a dirty condenser coil. We’ll verify system sizing, tighten thermostat wiring, and clean coils to fix it.
4. Strange Noises from the Unit
Rattling, squealing, or grinding sounds usually point to loose parts, worn bearings, or a failing blower motor. Turn off the system and give us a call. We’ll inspect fans, belts, bearings, and mounts to replace damaged components safely.
5. Water Leaks or Humidity Issues
If you see water around your indoor unit, it might be a clogged condensate drain line or a frozen evaporator coil. Clean the drain with a wet/dry vacuum or call us to blow it out professionally. If coils are frozen, we’ll check refrigerant levels and airflow to correct the root cause.
6. Rising Energy Bills
Unexpectedly high cooling costs often signal low efficiency. Furnace filters, old thermostats, and failing components can all drive up usage. We recommend spring tune-ups, including filter changes, duct inspections, and performance diagnostics to keep running costs low.
7. Thermostat Won’t Respond
A faulty thermostat can misread temperature or fail to signal the AC. Check its batteries, settings, and ensure it’s placed away from direct sunlight. If it still misbehaves, we can test and replace it with a smart or programmable model for better control.
8. AC Won’t Turn On
No power? Check circuit breakers and thermostat batteries. If breakers are fine and power is on, your outdoor disconnect switch might be off or the capacitor might be failing. We’ll check wiring, switches, and test the capacitor safely.
Preventive Maintenance Matters Most
Many AC problems are avoidable with regular maintenance. We typically recommend a spring inspection to clean, tune, and test your system so it runs smoothly all summer long.
