Why does my AC stop working at idle?

This can be caused by dirty coils, low refrigerant, or electrical issues. Call Blue Collar Heating & Cooling today to schedule a diagnostic and get your system running right again.

Why does my AC only blow cold air sometimes?

It may be a thermostat problem, clogged filter, or low refrigerant charge. Contact our team to inspect your system and restore consistent cooling.

Why does my AC keep raising the temperature?

Your thermostat may be faulty, set incorrectly, or your system is struggling due to poor airflow or low refrigerant. Schedule a service appointment today to have your system and thermostat checked.

Why does my AC keep freezing up?

Restricted airflow, dirty filters, or low refrigerant often cause frozen coils. Let our technicians identify the cause and prevent future freeze-ups—book your service now.

Why does my AC have no power?

Check the breaker and thermostat batteries. If those are fine, the issue could be electrical. If your AC still won’t turn on, call Blue Collar Electric for a full electrical inspection.

Why does my AC compressor shut off after 2-3 minutes?

This could be short cycling, often caused by thermostat issues, dirty coils, or refrigerant problems. Schedule a system evaluation today to stop short cycling and improve efficiency.

Why is my AC leaking water?

Usually a clogged drain line or frozen coil melting. Our technicians can clear the blockage and prevent damage—contact us today for a quick fix.

Where is the evaporator coil on an AC unit?

It’s located inside your indoor air handler or furnace cabinet, typically above the blower motor. If you’re unsure or need cleaning or maintenance, call us for professional service.

When to call HVAC repair?

If your AC is blowing warm air, leaking, making unusual noises, or your energy bills spike. Don’t wait until it fails—book a repair appointment today to keep your system running smoothly.

Why is my Air Conditioner blowing hot air?

This often means low refrigerant, dirty coils, or a faulty compressor. Schedule a service visit to identify and repair the problem before it gets worse.

Why is my AC unit sweating?

Condensation forms when warm, humid air hits cold surfaces. Excess sweat may signal poor insulation or airflow issues. Have one of our experts inspect your system to stop excess condensation and protect your unit.

Why is my AC thermostat not working?

Dead batteries, loose wiring, or a failing thermostat are common causes. If a quick battery change doesn’t help, contact us to test and replace your thermostat.

Why is an AC coil frozen?

Restricted airflow or low refrigerant causes the coil to drop below freezing and ice over. We can diagnose the root cause and thaw your system safely—book your appointment today.
