If your unit stops cooling during the day, our licensed technicians can be dispatched and have your system diagnosed the same evening. While we don’t run calls past 10 PM, our customers appreciate the peace of mind knowing that, with one call, their comfort can be restored that same day. This approach has helped us earn repeat business and word-of-mouth referrals throughout the community.

We repair all major brands of HVAC equipment. Whether your system is Lennox, Carrier, American Standard, or any other make, our technicians have the experience and tools to get it running again. For new installations and system replacements, we recommend and install Trane and Goodman—two of the most trusted names in the industry. These brands are known for energy efficiency, durability, and excellent warranties, making them a smart investment for homeowners in Sugar Land. Choosing Critical Air means choosing a partner who can handle both today’s repair and tomorrow’s replacement with the same level of expertise.

We charge an $89 consultation fee, which covers a complete diagnostic of your system. Unlike some contractors who charge a service fee on top of the repair, Critical Air applies your $89 directly toward the cost of your repair. This means you don’t pay twice for the same visit. For new customers, we also offer a 10% discount on the first repair (up to $50)—excluding refrigerant and new equipment. Homeowners appreciate our straightforward approach because it makes budgeting easier and eliminates hidden charges. Pair this with our Wells Fargo financing for larger projects, and you have flexible options to get your system running without financial stress.

Yes. While AC repair is our feeder service, one of our most profitable and impactful services is full AC and heating system replacement. Homeowners in Sugar Land often ask when it’s worth replacing instead of repairing. Generally, if your system is more than 10–12 years old, requires frequent costly repairs, or struggles to keep up with Texas summers, replacement may be the better long-term choice. Our team helps homeowners compare repair costs against replacement benefits, such as improved efficiency, lower energy bills, and stronger warranties. Many customers say they wish they had replaced sooner because of the comfort and savings they gained.

We don’t lock homeowners into formal maintenance contracts. Instead, we recommend bi-annual tune-ups—one in spring for your AC and one in fall for your heating system. This approach gives customers flexibility while still ensuring their systems are ready for peak season. During a tune-up, we check refrigerant levels, inspect wiring, test airflow, clean coils, and verify safety components. Many Sugar Land homeowners schedule their tune-ups with us because they trust our 20+ years of experience and know that preventive care saves money by avoiding emergencies. Even without a contract, we encourage scheduling these visits in advance so your system is prepared when you need it most.
