Here's How We Fix Your AC

First, we listen to what’s happening with your system. Strange noises, warm air, won’t turn on – these details help us narrow down the issue before we even arrive.

Our technician shows up with a fully stocked truck and runs a complete diagnostic. We check electrical connections, measure refrigerant levels, test components, and inspect the entire system. No guessing games.

You get a clear explanation of what’s wrong and what it costs to fix before any work begins. Most repairs happen right then and there. We test everything thoroughly before we leave to make sure your AC is running properly and efficiently.

Complete Air Conditioning Repair Coverage

We handle every type of AC repair you’ll encounter. Compressor failures, refrigerant leaks, electrical problems, frozen evaporator coils, faulty thermostats, and blower motor issues. If it’s part of your air conditioning system, we fix it.

Medfield’s summer heat puts extra strain on AC units, especially older systems. We see a lot of capacitor failures and refrigerant issues when temperatures spike. Our trucks carry the most common parts so we can complete repairs without multiple trips.

Dempsey Comfort Club members get priority scheduling during peak season and special rates on repairs. It’s designed for homeowners who want their HVAC system maintained properly year-round, not just fixed when it breaks.

Most AC repairs in Medfield happen the same day you call, especially during regular business hours. We keep common parts like capacitors, contactors, and thermostats on every truck. For more complex issues like compressor replacement, we typically schedule within 24-48 hours once we’ve diagnosed the problem. Emergency calls get priority, and we’ll work evenings and weekends when your AC goes down during heat waves.
AC repair costs depend on what’s actually broken. Simple fixes like replacing a capacitor or thermostat run much less than major component replacement. We give you the exact cost upfront before starting any work – no surprises or hidden fees. Most homeowners in Medfield spend between $200-800 for common repairs, though complex issues can cost more. We’ll always explain your options and help you decide what makes sense for your situation and budget.
Yes, we repair all major AC brands including Carrier, Trane, Lennox, Rheem, Goodman, York, and others. Our technicians are trained on both older and newer systems, so age isn’t usually an issue. We work on central air systems, ductless mini-splits, and heat pumps. Even if you have an unusual brand or older model, we can typically source parts and get it running. The key is proper diagnosis – once we know what’s wrong, we can almost always fix it.
It depends on the age of your system, what’s broken, and how much the repair costs. Generally, if your AC is under 10 years old and the repair costs less than half of replacement, fixing it makes sense. For older systems or expensive repairs like compressor replacement, replacement might be smarter long-term. We’ll give you honest advice based on your specific situation – we’re not trying to sell you a new system if a repair will give you several more good years.
Several things cause poor cooling during hot weather. Low refrigerant from leaks is common, especially in older systems. Dirty air filters restrict airflow and make your AC work harder. Frozen evaporator coils happen when airflow is blocked or refrigerant is low. Sometimes it’s as simple as a bad thermostat or electrical connection. We’ll check all these possibilities during our diagnostic and fix whatever’s causing the problem. Don’t ignore poor cooling – it usually gets worse and more expensive if left alone.
Yes, we provide emergency AC repair throughout Medfield and Norfolk County. When temperatures soar and your AC fails, that’s genuinely an emergency, especially for families with young children or elderly residents. We prioritize emergency calls and often respond within a few hours. Emergency service does cost more than regular appointments, but we’re upfront about those rates. Dempsey Comfort Club members get discounted emergency rates and priority scheduling even during the busiest summer days.
