Maintaining a comfortable home environment year-round requires more than just a working thermostat; it demands a dedicated team of experts who understand the intricacies of modern heating & cooling systems. From emergency repairs to routine maintenance and high-efficiency installations, AAA Home Services provides the comprehensive care your HVAC system needs to run smoothly, safely, and efficiently.
Complete Heating & Cooling Solutions for Your Home

We understand that St. Louis weather is unpredictable. You might run your furnace in the morning and your air conditioner in the afternoon. That is why our technicians are factory-trained to handle the full spectrum of residential HVAC needs. We don't just fix parts; we analyze your entire system to ensure optimized airflow, energy efficiency, and long-term reliability. When you search for "heating & cooling near me," you aren't just looking for a quick fix—you are looking for a partner who can guarantee year-round peace of mind.
Professional Heating Services You Can Trust
When the temperature drops, your furnace becomes the most important appliance in your house. A reliable heating system is essential for your safety and comfort. Our team is equipped to handle everything from minor glitches to major system failures on all brands and models of gas and electric furnaces.
If your system is making strange noises, cycling frequently, or failing to keep your home warm, it is time to call the experts. We provide fast and effective furnace repair to get your heat back on quickly. Our technicians arrive with fully stocked trucks, ready to diagnose and resolve issues on the spot.
Furnace Repair and Maintenance

Heating System Installation & Replacement
Sometimes, a repair isn't the most cost-effective solution. If your furnace is over 15 years old or requires frequent fixes, it might be time for a replacement. As an American Standard Platinum Dealer, we offer top-tier high-efficiency systems that can significantly reduce your monthly utility costs. Our furnace service team will provide a fair and honest assessment, helping you choose the right unit size and model for your specific home layout.
Reliable Air Conditioning Services for Hot Summers
Missouri summers are notorious for their heat and humidity. A struggling air conditioner can make your home feel unbearable in minutes. Just as we handle your heating needs, AAA Home Services is your go-to expert for staying cool.
We offer responsive ac service to tackle common summer problems like frozen coils, refrigerant leaks, and compressor failures. When your AC goes out, you don't have time to wait. You need a technician who respects your time and your budget.
AC Repair and Tune-Ups
Don't let a minor rattle turn into a mid-summer meltdown. Our skilled technicians perform thorough ac repair to restore your system's performance. We also highly recommend pre-season tune-ups. Cleaning your condenser coils, checking refrigerant levels, and calibrating your thermostat are all part of our standard heating & cooling maintenance protocols. These simple steps can improve your cooling efficiency by up to 20%, keeping more money in your pocket.
Energy-Efficient Cooling Upgrades
If your current air conditioner uses R-22 Freon or is struggling to dehumidify your home, it may be time to upgrade. Modern systems are vastly more efficient and quieter than models made just a decade ago. We can help you select and install a new system that handles the "cooling" side of your heating & cooling equation with ease.
The AAA Home Services Advantage
Choosing a service provider is about trust. You are inviting someone into your home, and you need to know they are qualified, background-checked, and honest.
