How to Know if You Need AC Repair

Here are some red flags that trouble may be around the corner and it’s time to call an HVAC technician from May's Heating & Air:

AC is blowing hot air

If heated air is blowing out of your AC unit instead of cool air, or if the air isn’t as cool as it should be, it’s a smart move to call us for professional cooling service.

Air conditioning keeps turning on and off

If your AC system cycles frequently instead of running consistently, it could be a sign of several problems and should be looked at by one of our certified HVAC technicians.

Monthly utility bills increase for no apparent reason

Odd odors are coming from your air conditioner

Air conditioners should not stink. Unusual odors coming from your air conditioner should be checked by an expert, as they can be a sign of problems like mold, mildew or even electrical issues.

If you hear odd noises when your AC system is running — clanking, scraping or screeching, to name just a few — it’s important to call for professional HVAC service to get to the bottom of the issue.

AC Repair FAQ

Common signs include warm air from vents, rooms that won’t cool evenly, new or loud sounds from the system, water leaking or moisture around the unit, frequent cycling, or higher-than-normal energy bills. If your system struggles to keep up, it’s best to book an inspection.

This is often caused by incorrect thermostat mode, restricted airflow, low refrigerant from a leak, ice buildup on the indoor coil, a dirty condenser coil, or electrical/capacitor problems. A technician can test pressures and components safely and recommend the proper repair.

If you notice burning smells, sparking, or tripped breakers repeatedly, turn the system off and schedule service right away. For milder issues like minor airflow problems, running it may be okay short-term, but you could turn a small issue into a bigger repair.

Many repairs are completed in one visit, but timing depends on the problem, how easy the components are to reach, testing requirements, and parts availability. After diagnosing, your technician should provide a clear timeframe.

Replacement may be the better option if the system breaks down often, is older and inefficient, uses outdated refrigerant, or has a major component failure like a compressor. If the issue is isolated and the unit has been reliable, repair is often the most practical choice. A pro can help you weigh long-term value.
