Complete AC Services Rochester

Everything Your AC System Needs

Dempsey Energy handles the full range of air conditioning services, from routine maintenance that prevents breakdowns to emergency repairs that get you back to comfortable temperatures fast. We service all major AC brands and can handle everything from simple filter changes to complete system replacements.

Rochester’s humid summers put extra strain on AC systems, which is why our maintenance programs focus on the components that fail most often in this climate. Regular tune-ups catch refrigerant leaks, electrical issues, and worn parts before they cause expensive damage or leave you without cooling.

For older systems, we provide honest assessments about repair versus replacement options. You’ll get realistic advice about what makes financial sense based on your system’s age, condition, and repair history – not just what generates the biggest invoice.

How often should I have my air conditioning system serviced?

Most AC systems need professional maintenance once a year, ideally in late spring before the cooling season starts. This gives technicians time to identify and fix problems before you’re relying on your system daily. If your AC is older than 10 years or you’ve had reliability issues, twice-yearly service can help catch problems earlier. Regular maintenance typically includes cleaning coils, checking refrigerant levels, testing electrical connections, and replacing filters – all things that prevent the most common causes of AC breakdowns during hot weather.

What should I do if my AC stops working completely?

First, check your thermostat settings and make sure the system is set to “cool” with the temperature set below the current room temperature. Then check your circuit breaker – AC units sometimes trip breakers, especially during hot weather when they’re working hard. If those basics don’t solve it, turn the system off and call for service. Running a malfunctioning AC can cause more expensive damage. Many AC problems that seem catastrophic are actually straightforward repairs when caught early, but continuing to run a failing system often turns simple fixes into major replacements.

How do I know if my AC needs repair or replacement?

Age is the biggest factor – most AC systems last 12-15 years with proper maintenance. If your system is over 10 years old and needs frequent repairs, replacement often makes more financial sense. Other signs include rising energy bills, inconsistent cooling, strange noises, or repairs that cost more than half the value of a new system. A good technician will give you honest numbers: what repairs will cost, how long they’re likely to last, and what replacement would run. The decision usually comes down to whether you’re fixing problems or just delaying the inevitable.

Why is my AC running but not cooling the house effectively?

Several issues cause this problem, and most are fixable. Low refrigerant from a leak is common – your system needs the right amount of refrigerant to absorb and release heat properly. Dirty coils also reduce efficiency since they can’t transfer heat effectively. Sometimes it’s airflow problems from clogged filters, blocked vents, or ductwork issues. Older systems might simply be undersized for your home’s current needs, especially if you’ve added rooms or improved insulation. A proper diagnosis checks refrigerant levels, coil condition, airflow, and system capacity to identify the real cause rather than guessing.

What's included in regular AC maintenance service?

Comprehensive AC maintenance covers the components that cause most breakdowns and efficiency problems. This includes cleaning indoor and outdoor coils, checking and adjusting refrigerant levels, testing electrical connections and controls, lubricating moving parts, and replacing filters. Technicians also inspect ductwork connections, test thermostat operation, and check for signs of wear that could cause future problems. Good maintenance visits include efficiency testing to make sure your system is operating at peak performance, which keeps energy bills lower and extends equipment life. Most services also include a written report of findings and recommendations for any issues discovered.

How quickly can you respond to AC emergencies during hot weather?

Emergency AC calls get priority scheduling, often with same-day service during regular business hours. Response time depends on the current service load and your location, but most emergency calls in the Rochester area get attention within a few hours. During extreme heat waves when everyone’s AC is working overtime, demand is higher, but emergency situations – especially for elderly customers or homes with medical needs – get fastest response. Having a maintenance relationship or Comfort Club membership typically means faster emergency service since your system information is already on file and you’re a priority customer.
