“Our air went out in the middle of the night. A+ Derr had Ricky out to us at the first part our day. Ricky was great he diagnosed the issue quickly, and had the part to get things cooling again. He also said that it would take some time to get things cool again. He was out the door and we could already feel the relief. Thanks Ricky!”

Home Service for Different Generations of Mount Washington Homes
Mount Washington’s housing spans very different periods. Historic downtown represents the community’s older housing, while a large concentration of suburban properties arrived during several later decades of development. That variety matters when something in the house stops working because the age of the property does not tell us what equipment or systems are currently inside.
You can see some of that history in places such as the James M. Lloyd House, Henry J. Barnes House, and Zach Stansbury House, which are listed on the National Register of Historic Places. From that older side of Mount Washington to later suburban properties throughout the 40047 area, we start with the home and system in front of us rather than assuming what we will find.
Heating Service as Mount Washington Turns Colder
Four distinct seasons mean Mount Washington homeowners eventually make the switch from cooling back to heating. That is when a furnace, boiler, heat pump, or other heating system that has been sitting through warmer weather needs to be ready to take over.
A+ Derr provides:
- Heating repair
- Heating installation
- Heating replacement
- Heating maintenance
- Boilers
- Furnaces
- Heat pumps
- Ductless mini-splits
- Ductless heating installation
- Ductless heating repair
- Ductless heating maintenance
- Geothermal
- Indoor air quality
- Emergency heating
When we come out for a heating problem, we start with the equipment you have and what it is doing. This is especially important across Mount Washington’s different generations of housing because we cannot determine the age or condition of a heating system simply by knowing when the house was built. We inspect the existing equipment and explain whether repair, maintenance, replacement, or installation makes sense based on what we find.

- AC maintenance
- Ductless mini-splits

Electrical Work Across Mount Washington’s Established Housing
The electrical project you need today may have little to do with when your Mount Washington home was originally built. Homeowners repair circuits and outlets, change lighting, add generators and EV chargers, or reach a point where a panel, meter, or electrical service needs attention.
A+ Derr handles:
- Electrical repair
- Electrical installation
- Generators
- Lighting services
- Surge protection
- Panel and meter upgrades
- Circuit and outlet services
- EV chargers
- Electrical service upgrades
- Commercial lighting
The range of housing around the 40047 area is one reason we look at the existing electrical system before deciding what a project requires. A home from Mount Washington’s later suburban development may not have the same electrical setup today that it had when it was built. If you are adding equipment or planning an upgrade, we first need to understand the existing system and the work you want it to support.
