AC Replacement & Installation in Louisville & Lexington
Is your air conditioning unit getting on in age? It seems every year, the summers just get hotter. Many homeowners find that their older AC units cannot handle the intensive heat wave streaks. These older units run 24/7 but just can’t put out enough cold air to keep up with the intensive summer heat. We want to help keep you cool through the summer.
At Dauenhauer Plumbing, Heating & Air, we replace and install cooling systems in Lexington, Louisville, and the surrounding areas.
Benefits of Replacing Your Air Conditioning Unit
Is your AC over 15 years old? Does it require frequent repairs, or does your energy bill keep increasing? Over time, as your AC unit gets older, it starts developing inefficiencies and requiring more energy to do the same level of work.
Here are five benefits of replacing your AC with a newer, more efficient unit:
- Improved Efficiency: New air conditioners are always more efficient than older, outdated models. Old ACs can have SEER ratings of six to 10, whereas newer ones have a SEER rating of at least 14, and the premium units can have efficiency ratings of up to SEER 30.
- Improved Comfort: Your new air conditioner should be sized correctly for your home and can handle the summer heat waves.
- Fewer Repairs: New ACs won’t require repairs like older ones.
- Better for the Environment: The less energy you use, the better it is for the environment. Older refrigerants like R-22 are still commonly used in older ACs but have been banned from production due to environmental concerns.
If you’re ready to replace your AC unit with a new one, call Dauenhauer Plumbing, Heating & Air. We professionally install new ACs in Lexington, Louisville, and the surrounding areas. We also offer AC maintenance services to ensure your new AC works for a long time.

What to Look for When Upgrading Your Air Conditioning System
You want to make sure that the unit you choose fits seamlessly into your routines, space, and style. It’s about blending the model with your previously established style instead of uprooting your life to fit the unit.
Modern air conditioners come in sleek, easy-to-use models, so you don’t have to worry about rearranging. Another thing to consider is cost. If you can afford to upgrade, go for it. If not, it is completely acceptable to opt for the standard model that fits your budget best.
We’ll Help You Choose the Perfect Replacement Air Conditioner
Decision fatigue is real. With all of these readily available options, how do you know what to choose? Our AC experts are available around the clock to help you choose the replacement AC unit for you and your home.
Central air conditioners are best for homes with multiple rooms or a target airflow that spreads beyond a small space. On the other hand, you want to avoid choosing a unit that’s too large for your home, as this will negatively affect airflow.
The most expensive units we offer have a SEER (Seasonal Energy Efficiency Ratio) rating, normally sitting at 25. Older units will have a SEER rating of 13-25. The model you choose will impact how fast air is produced, so choose one that fits your desired airflow.
Types of Air Conditioning Systems We Recommend for Kentucky Homes
Kentucky homeowners need substantial heat protection during peak summer months like July and August. To maintain optimal protection against high humidity, moisture, and heat transfer, a fast-acting air conditioner is mandatory. We recommend a few available systems that combat Kentucky-specific conditions, such as excess heat:
Central Air Conditioners
A central air conditioning system is the best way to ensure cool air flows through every room in your home, especially when you need it most. Simply power on the unit by using the thermostat. Central units are installed either on the roof or outside of the home. They work by passing cool air through ducts.
Ductless Mini-Splits
Similar to central units, ductless mini-splits have two working parts: one inside the home and one outside. The two work together to produce, move, and cool air to be used indoors.
All systems consist of an outdoor and indoor compressor and condenser. Tubes are connected to wall-mounted units to pass air through and have a built-in blower.
Geothermal Units
Geothermal air conditioners are an upgraded prototype that uses technology for both heating and cooling purposes. They use a metal coil that extends from your property into the ground for air passage.
You can yield different types of air this way. During the summer months, units extract hot air from the ground and push it away from your home. The opposite process is done in the winter.

Professional AC Installations and Replacement Services
No matter how advanced or efficient your new AC is, its efficiency will be wasted if it is installed poorly. Incorrect sizing of the air handler or ducts, no duct inspection or testing, or poor positioning or gaps can all cause serious problems. Even the sizing of the AC unit itself compared to the house is a critical calculation that should be done by a professional.
A unit that is too small will have insufficient output, and an overly large one will be subject to short cycling and a resulting shortened service life. But with the professionals at Dauenhauer, you’ll be in excellent hands. We’ll do a complete heating and cooling load calculation for your house. We consider many things, like your home’s orientation to the sun, the number of windows, floors, square footage, ceiling height, insulation quality and quantity, and other factors, to determine precisely what size of AC your home requires.
Our HVAC technicians have been vetted to find the best individuals who continually push for excellence. Our technicians arrive on schedule and work quickly. Most installations can be completed within one or two days, depending on the condition of your home’s ductwork.

Documentation includes taking photos or videos of your newly installed unit so that we have physical evidence of a job well done. This additionally aids in the insurance claims process if anything does happen to your unit.
