Air Conditioning FAQs
Get answers to the most common questions about AC repair, installation, and maintenance in the Kansas City metro area.
How long does a central air conditioning installation take?
A standard central AC installation typically takes one day for a straightforward replacement. If new ductwork or significant modifications are needed, it may take an additional day. Our team in Belton, MO works efficiently while maintaining the highest quality standards. We always clean up after ourselves and test the system thoroughly before leaving your home.
Why is my AC running but not cooling my house?
There are several common causes: a dirty air filter restricting airflow, low refrigerant levels due to a leak, a frozen evaporator coil, a malfunctioning thermostat, or a failing compressor. Some of these are simple fixes, while others require professional attention. If your AC is blowing warm air, we recommend calling us for a diagnostic to prevent further damage to your system. We serve Belton, Raymore, Lee's Summit, and the entire Kansas City area.
What size AC unit do I need for my home?
The right AC size depends on several factors, including your home's square footage, insulation, number of windows, ceiling height, and local climate. An oversized unit cycles on and off too frequently, wasting energy and creating humidity issues, while an undersized unit struggles to keep up. Our technicians perform a Manual J load calculation to determine the perfect size for your home, whether you are in Overland Park, Grandview, Leawood, or anywhere in the KC metro.
How can I lower my cooling costs in the summer?
Several strategies can help: schedule annual AC maintenance to keep your system running efficiently, replace air filters monthly during heavy use, use a programmable or smart thermostat, seal air leaks around windows and doors, and keep blinds or curtains closed during the hottest part of the day. If your AC unit is over 10-15 years old, upgrading to a modern high-efficiency system can significantly reduce your energy bills.
