Guide checked October 2026. How we verify licenses
In Texas, air conditioning calls peak in the hottest summer months. Spring is the easiest time to book a tune-up or replacement, before the first heat wave.
We scored 1,018 Houston HVAC contractors on ten factors, weighted as shown. A business is ranked when its trade is confirmed and it has 3 or more Google reviews or a claimed profile. A business with no Google reviews scores zero on rating, review volume and recency. Other unknown factors are left out, not counted as zero. Scores last refreshed October 22, 2026.
Paid placement never changes a rank or score. Featured businesses are paid, labelled, limited to 3 and shown above the ranking, outside it.
