Ace Comfort Air Conditioning & Heating

Texas does not have a single statewide HVAC contractor license, but there are mandatory federal and local requirements. Technicians who handle refrigerants must have EPA Section 608 certification, many contractors carry industry credentials such as NATE or manufacturer training, and reputable contractors should be able to pull required city permits and arrange inspections for work in Houston. Always ask for proof of insurance, references, and documentation that the contractor will obtain any necessary permits before work begins.

Have a qualified contractor perform a professional load calculation (Manual J) so the system is sized for Houston’s high heat and humidity — oversizing reduces dehumidification and comfort. Consider efficiency (SEER), proper duct design and sealing, adequate airflow, and features that improve humidity control (variable-speed blower, two-stage or variable-capacity compressors, or a dedicated dehumidifier). Ask about refrigerant type, installation details, and how the proposed system will handle both peak cooling and humidity removal.

A clear written estimate should list equipment brand/model, capacity and efficiency (SEER), scope of work (including duct modifications, permits, and disposal), labor warranty, manufacturer warranty terms, timeline, and payment terms. Simple repairs can be completed in a few hours; a full system replacement is commonly scheduled for 1–3 days of on-site work but may take longer when permits, inspections, or special parts are required. Get all warranties and maintenance requirements in writing and ask whether the contractor registers manufacturer warranties or offers a labor warranty for their work.
