Newmark Air Conditioning is a Houston HVAC company celebrating 25 years in business, with a perfect 5-star rating across 30 reviews and a warranty policy that stands out in the local market: a 10-year parts and labor warranty on qualifying installations. Operating 24/7, Newmark covers AC installation, repair, and maintenance; heating service including electric heaters, gas heaters, boilers, heat pumps, and geothermal systems; furnace services; ductwork; insulation; and indoor air quality solutions.

The 10-year parts and labor warranty is the company's headline differentiator. Most contractors warranty labor for one year and parts for up to ten — Newmark bundles both together. For complete system replacements, the current promotional offer includes $0 down, 0% interest for 24 months, $0 payments for the first year, and $0 on the next five service calls. The company also offers up to $2,000 in 2025 rebates and a referral program paying up to $1,000 in gift cards for qualified referrals.

A standout policy is the on-time guarantee: if a technician doesn't arrive within the scheduled window, the customer pays nothing for the service call. Technicians are background-screened before hiring.

Reviews emphasize competitive pricing — one customer noted Newmark can negotiate better equipment pricing through volume purchasing — and highlight technicians Melvin, Francisco, and Marcos for being responsive, professional, and clean. Marcos's team reorganized its schedule to accommodate an emergency remodel situation at short notice.

Newmark serves the greater Houston area. Online estimates are available, and the company accepts credit cards and NFC payments.
