AC Repair Service Process

Simple Process, Fast Results

First, we listen. You tell us what’s happening—no cool air, strange noises, high electric bills, or whatever the problem is. We schedule you for same-day service because we know you can’t wait around in a hot house.

Our technician arrives with a fully stocked truck and runs a complete diagnostic. We don’t guess or throw parts at the problem. We test electrical components, check refrigerant levels, inspect your ductwork, and identify exactly what’s causing the issue. Then we explain what we found in terms you can understand.

Before we touch anything, you get upfront pricing. There are no unpleasant surprises, hidden fees, or “oh, we found something else” after we’ve already begun. You approve the work, we complete the repair, and you’re back to comfortable living. Most jobs are finished the same day, and everything comes with our workmanship guarantee.

Complete AC Repair Services

Every Repair Need Covered

We handle everything from simple fixes to major component replacements. We can fix compressor failures, refrigerant leaks, electrical problems, frozen coils, and thermostat issues that are preventing your AC from cooling properly.

Our trucks carry the most common parts for all major AC brands, so we can complete most repairs without making you wait for special orders. When we do need to order parts, we explain the timeline upfront and can often provide temporary solutions to keep you comfortable.

Beyond emergency repairs, we offer preventive maintenance through our Dempsey Comfort Club. Regular tune-ups catch small problems before they become expensive breakdowns and keep your system running efficiently all summer long. Members get priority scheduling and discounts on repairs—because preventing problems is always better than fixing them.

We offer same-day service for AC emergencies in Fairhaven and throughout Bristol County. When you call before 3 PM on weekdays, we can usually have a technician at your door within a few hours. We add weekend availability and extend our hours during the busiest summer months because we understand that air conditioning issues don’t wait for convenient times. Our dispatch team will give you a realistic time window when you call, and our technicians will call ahead when they’re on their way to your home.
We work on all major AC brands and keep relationships with suppliers who can source parts for older systems. Our technicians have experience with units going back decades and often know workarounds when exact replacement parts aren’t available. However, if your system is beyond economical repair, we will clearly explain your options. Sometimes a repair that costs 60% of a new unit’s price isn’t the smart choice, and we’ll tell you that upfront rather than take your money for a temporary fix.
We provide upfront, flat-rate pricing for all repairs before any work begins. No hourly charges, no surprise fees, no “we found something else” after we’ve started. Our technician will diagnose the problem, explain what needs to be done, and give you the total cost. You approve the work before we proceed, or you pay nothing except our diagnostic fee. This approach protects you from bill shock and lets our technicians focus on doing the job right instead of watching the clock.
Sometimes, yes. We’ve seen cases where other companies missed the real problem or quoted replacement when a good repair was possible. Our diagnostic process is thorough—we don’t stop at the first problem we find. However, we won’t deceive you or offer a repair that won’t endure. If your system truly is beyond economical repair, we’ll explain why and discuss your replacement options. Our goal is to give you the most cost-effective solution, whether that’s repair or replacement.
All our repair work comes with a workmanship guarantee that covers our labor and any parts we install. The warranty period depends on the specific repair—major component replacements typically carry longer warranties than minor fixes. We also honor manufacturer warranties on new parts. If something we repaired fails within the warranty period, we’ll return and make it right at no additional charge. We stand behind our work because our reputation depends on repairs that last, not callbacks.
The only thing you should try is checking your air filter and making sure your thermostat is set correctly. Beyond that, leave it to the professionals. AC systems involve high-voltage electricity, pressurized refrigerant, and delicate mechanical components. DIY repairs often make the original problem worse and can be dangerous. We’ve seen too many cases where homeowner “fixes” turned a simple repair into an expensive replacement. Save yourself the hassle and potential safety risks—call us first, and we’ll get it diagnosed and fixed properly.
