In 2026, the average cost for a full HVAC replacement (AC + Gas Furnace) in Houston ranges from $5,000 to $15,000, depending on the efficiency (SEER2) and home size. A standalone furnace installation typically ranges from $3,500 to $7,500. We offer 0% APR financing to make these costs manageable.
If your furnace is over 15 years old and the repair cost multiplied by its age is over $5,000, it’s time to consider a new heating installation in Houston. This formula ensures you don’t throw “good money after bad” on an obsolete system.
Because Houston has mild winters with only occasional freezes, heat pumps are increasingly popular due to their high efficiency (200-400%). However, if your home is already set up for natural gas, a gas furnace provides the most powerful heat during extreme cold snaps.
For a 2000 sq ft home, you typically need a 3.5 to 4-ton system. The combined cost for a new high-efficiency system installation usually falls between $8,000 and $13,000.
Your comfort shouldn’t be a gamble. Whether you need a simple Furnace Repair or a complete Heating Repair & Installation in Houston, 24 Seven AC is here. Ensure your system stays healthy with our AC maintenance plans and protect your indoor air with our IAQ solutions.
