“We had our annual checkup on our A/C unit. Michael Hanna was the lead technician and Wes assisted him. We’ve had Michael out a few times. I’ve been impressed with him each and every time. Very professional, courteous and knowledgeable. If I could get him to perform my inspections every time I definitely would in a heartbeat. Wes is definitely learning from one of the best.”

We Start With What You’ve Noticed at Home

When we walk into a Morganfield home, one of the first things we want to know is what you have been seeing, hearing, or feeling. Maybe one room suddenly feels warmer. Maybe the thermostat is not responding normally, a drain has started slowing down, or an outlet has stopped working. Those details can tell us a lot about where to start looking.

That approach matters because no two homes in the 42437 area are exactly alike. Equipment gets replaced, systems get updated, and homeowners make changes over the years. Instead of guessing based on the property, we start with your concern and work from there.

When Morganfield Heat Puts Your AC to Work

Summer around Morganfield brings plenty of activity, especially when the Morganfield Corn Festival fills the calendar with its parade, carnival, vendors, food, and live music. It is also the part of the year when your air conditioner or heat pump may be running day after day. If the house suddenly feels warmer or the system starts behaving differently, you want to know why.

Your cooling system may need attention when:

  • The AC runs but your home stays uncomfortable
  • Cooling suddenly stops
  • Your system needs a repair
  • A heat pump is not cooling properly
  • Ductless equipment develops a problem
  • The AC is due for maintenance
  • Existing cooling equipment needs replacement
  • You need a new cooling system installed
  • Indoor air quality needs attention
  • A loss of cooling requires emergency service

A+ Derr provides AC repair, installation, and maintenance along with ductless mini-splits, heat pumps, heat pump repair and maintenance, indoor air quality services, and emergency cooling. Whether we can get your existing equipment back on track or it is time to discuss replacement, the goal is to get your Morganfield home comfortable again.

“Requested service call for my thermostat not working correctly. My AC system was inspected and found to be ok. It was determined my thermostat was malfunctioning and was replaced. The technician was very efficient and explained how the system works”

Electrical Work for How You Use Your Home Today

Much of Morganfield’s housing dates from the 1940s through the 1980s, but the construction date does not tell us what electrical work has happened since. Panels can be changed, circuits added, lighting updated, and new equipment installed over the decades. What matters when we arrive is the electrical system serving your home today and what you need it to do.

Electrical projects and problems we handle include:

A+ Derr provides electrical repair and installation, generators, lighting services, surge protection, panel and meter upgrades, circuit and outlet services, EV chargers, electrical service upgrades, and commercial lighting. If you are adding something new, we can look at the existing system and determine what is needed to support the project rather than making assumptions based on the age of the house.

Furnace Repair

When Friday Nights Start Getting Colder in Morganfield

By the time Friday nights at Union County High School start getting chilly, plenty of Morganfield homeowners are making that first switch back to heat. Braves football is a familiar part of fall around here, and those cooler evenings are also a reminder that furnaces, boilers, heat pumps, and ductless systems are about to take on more of the workload.

Give us a call when:

  • Your furnace runs but the house stays cold
  • Heating equipment will not start
  • Your system needs seasonal maintenance
  • A boiler needs service
  • Your heat pump is not heating correctly
  • Ductless heating develops a problem
  • Existing equipment needs replacement
  • You are planning a new heating installation
  • Indoor air quality is a concern
  • You lose heat and need emergency service

We work on furnaces, boilers, heat pumps, ductless mini-splits, and geothermal systems, along with indoor air quality equipment.

One Team as Your Home-Service Needs Change

The Union County Fair is another familiar part of the Morganfield calendar, bringing 4-H activities, tractor pulls, and rodeo-style events to the area. Just as the local calendar changes through the year, what needs attention around your house can change too.

Spring might bring an AC maintenance visit. A plumbing problem can show up without much warning. An electrical project might come with changes you are making around the house, and eventually colder weather puts the heating system back in focus. A+ Derr works across all four service areas, so you have one team to call when the problem changes.

We also provide emergency heating and cooling when comfort cannot wait for a routine appointment. Whether you know exactly what is wrong or only know that something is not working the way it should, tell us what you have noticed and we can take it from there.
