Most Georgetown homeowners expect August to be brutal. What catches them off guard is June. By the time the calendar hits June, temperatures are already climbing into the mid-to-upper 90s, and your AC is being asked to do something it may not be fully prepared for: run almost continuously.
Why June Hits Harder Than You Think
Your air conditioner is designed to maintain a temperature difference of roughly 20 degrees between the outside air and your indoor setpoint. When outdoor temps push past 95 and you want 75 inside, your system has to work harder than it was engineered to work. Add humidity into the mix, and you have a system that is straining from the start of summer.
The problem is compounded by the fact that most HVAC systems in Georgetown have been sitting somewhat idle through the mild spring months. Components that were marginal in April look fine on paper. Then June arrives, the system runs 14 hours a day, and suddenly you are getting uneven cooling, long run cycles, or a system that cannot keep up with the afternoon heat load.
The Most Common June AC Problems We See
Low refrigerant. Refrigerant does not get used up, but it does leak. A slow refrigerant leak that was barely noticeable in spring becomes a major cooling problem when demand spikes in June. Signs include ice forming on the refrigerant lines, warm air from vents, and a system that runs constantly without reaching your setpoint.
Dirty condenser coils. Your outdoor unit's condenser coil is responsible for releasing heat from your home into the outside air. When it is coated with dirt, pollen, or grass clippings from the spring, heat transfer efficiency drops dramatically. This forces the compressor to work harder and shortens its lifespan.
Restricted airflow. A clogged filter, closed vents in spare rooms, or furniture blocking return air grilles can all create airflow problems that make your system struggle to cool the spaces you actually use.
An aging compressor. If your system is more than 12 years old and struggling in June, the compressor may simply be at the end of its useful life. Compressor failures tend to happen on the hottest days when demand is highest, which is exactly when you do not want to be without AC.
What You Can Do Right Now
A few simple steps can help your system handle June's heat load better:
Check and replace your air filter. Run your ceiling fans to help distribute cooled air. Clear at least two feet of space around your outdoor unit. Close blinds and curtains on south and west-facing windows during peak afternoon hours. Set your thermostat a degree or two higher during the hottest part of the day to reduce system strain.
If your system is struggling despite these measures, do not wait. A refrigerant leak or failing component will only get worse. A diagnostic visit from a qualified HVAC technician can identify the problem before it turns into a full system failure in the middle of a 100-degree Georgetown afternoon.
