Repair Your AC Fast

There is never a good time for an AC to break down. Your clients or family are too attractive. Your system either blows warm air or won't turn on at all. It's annoying to wait days for an HVAC technician to arrive. Additionally, attempting to patch things together with an unlicensed repair or do-it-yourself fix may wind up costing more in the long run. We react quickly when you need emergency AC repair.

We provide services for both residential and commercial properties, such as apartment complexes and small businesses. We provide skilled equipment, reliable parts, and years of practical experience for everything from indoor coil leaks to rooftop unit failures. Our objective is straightforward: fix it quickly and correctly.

Upgrade Your AC System

Is the cooling system you have now outdated? It's probably struggling to keep you cool and consuming more energy than it needs to. High cooling costs, inconsistent temperatures, noisy equipment, or constant repairs are signs your AC is ready for retirement. However, changing an HVAC system is a significant choice that needs to be guided by professionals.

We specialize in installing modern, energy-efficient cooling systems customized for your property. Choose from top-tier brands we’re licensed to install, including units backed by excellent warranties. We'll help you save energy, reduce your bills, and stay cool for many years to come with everything from zoned ductless mini-splits to smart thermostat integration. In addition, we take cash, checks, credit cards, and all other major payment methods, and we provide financing options.

Protect Your Comfort With Preventive AC Maintenance

Is your air conditioner ready to handle the heat waves? Even the best systems can malfunction when you need them most if they are not regularly maintained.

Skipping annual maintenance can lead to clogged filters, frozen coils, low refrigerant, or even full system breakdowns. In addition to decreasing efficiency, these problems shorten the lifespan of your system and necessitate expensive emergency repairs. If you don't follow the necessary service instructions, you might also be voiding your warranty.

At Citywide Heating & Cooling, our preventive AC maintenance service keeps your system operating at its best throughout the season. In order to identify minor issues before they become major ones, our certified professionals examine every part, including compressors, coils, motors, wiring, refrigerant levels, and more. We offer flexible scheduling, friendly reminders, and a membership program that includes priority service. Stay cool, save money, and protect your investment with regular tune-ups from our trusted St. Louis HVAC experts.
