Troubleshooting

Common AC Problems
We Fix

Experiencing one of these issues? Our technicians can diagnose and resolve it quickly, often on the same day you call.

AC Not Cooling

Low refrigerant, dirty condenser, or failing compressor. We pinpoint the root cause fast.

Strange Noises

Banging, grinding, or squealing signals mechanical issues. Early intervention prevents breakdowns.

High Energy Bills

Dirty filters, duct leaks, or an aging system. We optimize efficiency to lower your costs.

Refrigerant Leaks

Low refrigerant damages the compressor. Our EPA-certified techs locate leaks and recharge properly.

Common Questions

Frequently Asked
Questions

We offer same-day service for most AC repairs. In emergency situations, we can often dispatch a technician within 2-4 hours. Our goal is to restore your comfort as quickly as possible, especially during the peak summer months when you need it most.

Our diagnostic and repair service starts at $149, which includes the diagnostic fee that is waived if you proceed with the repair. The total cost depends on the specific issue and parts needed. We always provide upfront pricing and get your approval before any work begins -- no surprises.

As a general rule, if your system is over 10-15 years old and the repair costs exceed 50% of a new unit's price, replacement is usually the better investment. Our technicians will give you an honest assessment and help you weigh the pros and cons. We never push unnecessary replacements.

Yes, we offer flexible financing options to make a new AC installation affordable. We work with trusted lending partners to provide competitive rates and monthly payment plans. Ask about our current promotions when you schedule your free in-home estimate.

We service all major brands including Carrier, Lennox, Trane, Goodman, Rheem, Daikin, York, Amana, and many more. Our technicians are factory-trained and we carry common parts on our trucks for faster repairs. For installations, we can help you choose the best brand for your needs and budget.

We recommend an annual AC tune-up, ideally in the spring before the cooling season begins. Regular maintenance extends your system's lifespan by 5-10 years, improves efficiency by up to 15%, and helps prevent costly breakdowns during peak summer heat. Our $89 tune-up covers a comprehensive inspection and cleaning.
