We keep your business cool, efficient, and comfortable with expert commercial air conditioning service, repair, and installation.
At Williams Air Conditioning & Refrigeration, we help local businesses stay cool, productive, and open for business with dependable commercial AC services. If your building feels hot, humid, unevenly cooled, or your system is driving up energy costs, we can diagnose the problem and give you a clear solution. We are a family-owned company founded in 2007, and our team brings 45 years of combined hands-on HVAC and refrigeration experience to jobs across Madison and Marshall County, AL.
We know commercial cooling problems can affect employees, customers, equipment, and day-to-day operations fast. That is why we provide honest, straightforward service without gimmicks or surprise charges. Our goal is simple: restore comfort, improve efficiency, and help your business avoid costly downtime.
We service commercial air conditioning systems for a wide range of business properties, including offices, retail stores, restaurants, and other light commercial spaces. Whether you need a fast repair, system diagnosis, routine maintenance, replacement planning, or help with poor cooling performance, we are ready to help. We work on all HVAC brands and use a practical, solution-first approach based on the condition of your equipment and the needs of your building.
Business owners often call us when the AC stops keeping up, makes unusual noises, cycles too often, leaks, or causes hot and cold spots throughout the building. We also help when utility bills rise for no clear reason, indoor humidity feels too high, or staff and customers complain about comfort. These issues can point to worn parts, airflow restrictions, thermostat problems, electrical faults, refrigerant issues, or maintenance neglect.
We take the time to find the real cause instead of guessing. That helps prevent repeat breakdowns and wasted money on temporary fixes. If your commercial air conditioning system can be repaired responsibly, we will tell you. If replacement makes more sense, we can explain your options clearly.
A reliable cooling system does more than lower the temperature. It helps protect employee comfort, customer experience, electronics, inventory, and overall indoor air quality. In many businesses, poor climate control can slow productivity, create an unpleasant environment, and put extra strain on equipment.
Regular commercial AC service can also help reduce wear and tear, improve system efficiency, and lower the risk of surprise outages during the hottest part of the year. For business owners, that means better performance, fewer interruptions, and a better chance of extending the life of the system. Preventive service is often much less expensive than emergency repairs and lost business time.
We are a small, family-owned business, and that means we stay close to the work and accountable to our customers. When you call Williams Air Conditioning & Refrigeration, you get direct service from experienced professionals who care about doing the job right. We are licensed and insured for HVAC and refrigeration work, and we have built our reputation on honest communication and dependable results.
We do not rely on flashy specials or pressure tactics. Instead, we focus on straightforward pricing, solid workmanship, and responsive service. If your business has an urgent cooling problem after hours or on the weekend, we also offer emergency service because commercial HVAC problems rarely happen at a convenient time.
We proudly serve commercial customers in Madison and Marshall County, AL, including New Hope, Huntsville, and surrounding communities. From our office at 1314 Oak Grove Rd, New Hope, AL 35760, we support local businesses that need dependable climate control and fast response. We understand the needs of businesses in North Alabama and work hard to provide service you can trust.
We also aim to keep the process simple for owners, managers, and facility decision-makers. You will get clear communication, practical recommendations, and documentation sent by email after the visit. Financing and payment plan options may also be available for qualifying jobs, helping you manage larger commercial cooling expenses more easily.
It is a good idea to call as soon as you notice weak airflow, warm air, inconsistent temperatures, rising humidity, louder system operation, unusual odors, or repeated trips of breakers. Waiting too long can turn a smaller repair into a larger and more expensive issue. Early service can also help reduce wear on compressors, motors, and other major components.
If your commercial AC system has already stopped working, we can come out, diagnose the issue, and help you get your building comfortable again as quickly as possible. If the system is aging and repairs are becoming frequent, we can also help you compare repair costs versus replacement value in a simple, honest way.
If your business needs dependable commercial air conditioning service, we are ready to help. Whether you need emergency AC repair, routine maintenance, system diagnostics, or guidance on replacing aging equipment, Williams Air Conditioning & Refrigeration delivers experienced service with honest pricing. Call us today at (256) 426-9779 to schedule commercial AC service in Madison and Marshall County, AL, or use our website form to request an appointment.
When you call Williams Air Conditioning & Refrigeration, we schedule your commercial AC service quickly and send an on-the-way text before arrival. We review the cooling issue, equipment age, airflow, controls, and system performance so we can diagnose the problem accurately and minimize downtime for your business.
We perform a hands-on evaluation of your commercial air conditioning system, checking components like thermostats, refrigerant levels, coils, compressors, and electrical connections. Then we give you straightforward pricing with practical repair or replacement options, so you can choose what fits your building, budget, and timeline.
Once approved, we complete the commercial AC repair, maintenance, or installation work with attention to efficiency, reliability, and comfort. Before we leave, we test operation, confirm proper cooling performance, email your receipt, and make sure you know exactly what was done and what to expect next.

"If you are looking for someone honest that actually knows what they are talking about.......Please give Marty Williams a call!!!!!! I had a different company come to our home initially to diagnose our broken AC unit. Within 5 seconds of looking at it they gave me 2 very expensive options. We could either buy a new compressor + Coolant, or we could buy a whole new system for around $6,000. We wanted a second a opinion and spoke to some friends who have dealt with Marty in the past and he came highly recommended with glowing reviews from friends of ours! We called him and explained the situation. He was at our house first thing the next morning. Within seconds we found out that the first company had completely lied and Marty had the unit WORKING in a couple of minutes!! We are now having Marty clean and service both of our units as well as replace our fan motor so that it runs smoothly. We are going to save thousands of dollars and a massive headache because we called him. I cannot say enough good things about how nice and professional he was. So please listen to a happy customer who doesn't appreciate being lied to and call this company!"

Hey, at first, I called Hiller Air, not knowing my butt from a hole in ground and they were very professional, but over charge us by about 60%. They were gonna charge $1910 for changing the core, 2 capacitors and saving and then refilling the coolant again. Thank God, I called Marty Williams and he was able to do the whole job for $695. Hallelujah! I'm a believer!"

Cost was very reasonable and the technician was friendly and patient with explanations. When a minor issue about the repair arose weeks later, they sent someone within 1.5 hours of talking with them and they cheerfully fixed the minor issue for no charge."
"Referred by our realtor to Marty and he really helped us out - couldn't get our gas heat going in older home we purchased that had been sitting vacant for a while.
