Plumbing, HVAC & Electrical Services in Louisville, KY
Dauenhauer has been part of Louisville since 1958. That means our technicians grew up here, raised families here, and have worked on homes in every Louisville neighborhood from Portland to Prospect. We know which streets flood after a heavy rain. We know the housing stock in Cherokee Triangle differs completely from the new builds going up on the east end. That local depth is something no regional chain can replicate.
Louisville’s Biggest Plumbing Challenge: Water in the Wrong Places
Louisville sits in the Ohio River valley, and water management is a defining challenge for homes here. The Metropolitan Sewer District uses a combined sewer system, carrying both stormwater and sewage in the same pipes. During heavy rainfall events, the system can become overwhelmed, sending sewage backups into basements across the city. MSD has been under a federal consent decree for years, working to address this, but the problem affects homes right now.
If your basement has flooded or backed up during a heavy storm, you are not alone. Sump pump installation and maintenance is one of our most requested services in Louisville. A properly sized, maintained sump pump is the single most effective defense against a wet basement in this city.

HVAC: Navigating Louisville’s Humidity and Ice
Louisville’s climate is genuinely demanding. Summer humidity regularly makes 90-degree days feel closer to 105, and the HVAC systems in Louisville homes work harder than those in drier climates. Dehumidification is not optional here, it’s part of home comfort management. At the same time, Louisville gets its share of winter ice storms that can knock out power for days and stress heating systems that haven’t been serviced in years.
Services We Offer
- Central AC repair, installation, and seasonal tune-ups before the humid summer season
- Dehumidifier installation and whole-home humidity control — particularly important in older Louisville homes with basement moisture issues
- Furnace and heat pump repair — including emergency no-heat calls during ice storm events
- Indoor air quality solutions: air purification, duct cleaning, UV systems
- Ductless mini-split installation for additions, garages, and older homes without ductwork
- Commercial heating and cooling for Louisville businesses

Electrical Services in Louisville
Louisville’s older neighborhoods, the Highlands, Cherokee Triangle, Germantown, and Butchertown, contain beautiful homes that often carry their original electrical infrastructure. Knob-and-tube wiring in homes built before 1950 is still encountered regularly in this city. Panel upgrades, whole-home rewiring, and generator installation are among our most common electrical calls.
Ice storms make whole-home generator installation particularly valuable in Louisville. When a January ice storm takes down power lines across Jefferson County, a standby generator keeps your heat running, your sump pump operational, and your family safe without any manual intervention.
Services We Offer
- Electrical panel upgrades — essential for older Louisville homes
- Whole-home generator installation and maintenance
- Wiring inspection and rewiring for pre-1960 homes
- EV charging station installation
- Whole-home surge protection
- Smart home integration and lighting installation

Dauenhauer Louisville FAQs
My basement flooded during a storm — is that a plumbing issue or a drainage issue?
Usually both. Louisville’s combined sewer system can send sewage back through floor drains and toilets during heavy rain. A properly installed sump pump with a battery backup addresses groundwater intrusion; a backwater valve addresses sewer backup. We can assess your basement and recommend the right combination for your home.
My home is in the Highlands and was built in the 1920s. What should I have inspected first?
For homes of that era in Louisville, we typically recommend starting with a sewer camera inspection and an electrical panel evaluation. Clay sewer laterals in older Louisville neighborhoods are frequently cracked or root-infiltrated. Pre-1950 electrical panels often can’t safely carry modern loads. Both are safety and comfort priorities.
How do whole-home generators hold up during Louisville ice storms?
Very well. Standby generators are designed to activate automatically within seconds of a power outage. During a multi-day ice storm outage, they keep your heat, refrigerator, sump pump, and lights running without extension cords or fuel runs. We size and install Generac systems appropriate for your home’s load.
Do you offer dehumidifier installation?
Yes, we do. Whole-home dehumidifiers integrated with your HVAC system are significantly more effective than portable units. They manage humidity throughout the entire house, reduce the load on your AC, and protect against the mold risk that Louisville’s humidity creates in basements and crawl spaces.
