Most AC repairs in Rochester get same-day service, especially during peak summer months when we know you can’t wait. Simple fixes like replacing a capacitor or cleaning a clogged drain take 30-60 minutes. More complex repairs involving compressors or extensive electrical work might take 2-3 hours, but we’ll give you a realistic timeframe upfront. If we need to order a part that’s not on our truck, we’ll explain your options and get it handled as fast as possible.
AC repair costs depend on what’s actually wrong with your system. Minor repairs like replacing a thermostat or capacitor typically run $150-$400. More involved repairs like fixing refrigerant leaks or replacing major components can range from $400-$1,200. We always give you an upfront estimate before starting any work, so you know exactly what you’re paying. There are no surprise charges or hidden fees added to your bill later.
Yes, we service and repair all major AC brands including Carrier, Trane, Lennox, Rheem, Goodman, American Standard, and others. Our technicians carry common parts for most systems on their trucks, which means faster repairs for you. Even if you have an older or less common brand, we can usually source the parts needed and get your system running again. We’ll let you know upfront if your system is too old or damaged to repair cost-effectively.
It depends on the age of your system and the cost of the repair. If your AC is under 10 years old and the repair costs less than half of a replacement, it’s usually worth fixing. For systems over 15 years old, especially if they need major component replacement, you might save more money in the long run by upgrading to a newer, more efficient unit. We’ll give you honest advice about whether repair or replacement makes more financial sense for your situation.
Yes, we provide emergency AC repair service in Rochester and throughout Plymouth County. We understand that AC breakdowns don’t wait for convenient times, especially during heat waves when your family’s comfort and safety are at risk. Our emergency service includes evenings, weekends, and holidays. Emergency calls do carry additional service fees, but we’ll explain all costs upfront so you can make an informed decision about proceeding with the repair.
Our AC repairs are designed to be permanent solutions, not temporary fixes. We use quality replacement parts and follow proper repair procedures, which means most repairs should last for years without issues. All our repair work comes with a warranty – typically 90 days to 1 year depending on the type of repair and parts used. If the same problem comes back during the warranty period, we’ll return and fix it at no additional charge to you.
