Signs You Need AC Repair

Wondering if your air conditioner requires service? From a stinky smell to warm air coming from the vents, there are many symptoms that your cooling system has an issue and needs attention or service.

Here are some warning signs that trouble may be on the way and it’s time to call an HVAC technician from Knoechel Heating:

AC won’t blow cold air

If heated air is blowing out of your AC unit instead of cool air, or if the air isn’t as cold as you’d like, it’s a wise decision to call us for professional cooling service.

Air conditioner keeps turning on and off

If your AC system turns on and off instead of maintaining steady operation, it could be a warning of potential issues and should be looked at by one of our certified HVAC technicians.

Cooling bills spike for no apparent reason

A sudden spike in your energy bills can be an indicator your AC unit is losing efficiency, which means it uses more energy to keep your space comfortable and needs AC maintenance or repair.

Strange odors are coming from your air conditioning

Air conditioners should not stink. A strange smell coming from your air conditioning system should be evaluated by a professional, as they can be a red flag for issues like mold, mildew or even electrical issues.

AC makes loud noises when it runs

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

FAQ: AC Repair

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 schedule a diagnostic.

This is often caused by incorrect thermostat mode, a dirty air filter, low refrigerant from a leak, ice buildup on the indoor coil, a clogged outdoor unit, or electrical/capacitor problems. A technician can test pressures and components safely and recommend the right fix.

If you notice burning smells, smoke, or power issues that keep returning, shut it down and call a licensed HVAC professional. For non-emergency symptoms like minor airflow problems, running it may be okay short-term, but continued operation can worsen damage.

Many repairs are completed in one visit, but timing depends on the problem, how easy the components are to reach, diagnostic complexity, and whether parts are in stock. 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.
