About Celsius A/C & Heating
Celsius A/C & Heating has served Houston homeowners for more than two decades, building a reputation for responsive repairs and honest workmanship. The company holds a 4.8-star average across 42 verified reviews, a near-perfect score that reflects consistent quality over years of operation. Based in Houston, the team responds to calls throughout the greater metropolitan area, including neighborhoods like Meyerland, Galleria, and the Heights. Whether dealing with a failing condenser in mid-July or a heating malfunction on a cold winter night, residents know they can reach a local technician who understands the demands of life in southeast Texas.
What distinguishes Celsius from countless HVAC companies operating across Harris County is their commitment to rapid response alongside technical thoroughness. Multiple reviewers emphasize that Dean, the primary technician, arrived within 15 to 20 minutes of the initial call, even during late evening hours and on weekends. Rather than simply patching a problem and leaving, he inspects attic equipment, explains the root cause to curious homeowners, and verifies that the entire system operates properly before departing. This combination of speed and attention to detail prevents repeat call-backs and gives customers confidence their unit will run through the next heat wave.
The customer stories reveal a technician who treats each call as urgent, regardless of hour. Todd Lyda called at 9:15 pm and Dean arrived before 9:30, diagnosing and repairing a non-functioning unit in under 30 minutes total. Monica Jay needed help before a storm rolled through and Dean completed the job by 8:40 pm, answering her husband's questions with patience. Beverly Mullin describes an 11:30 pm call during an August heat wave, a time when a broken AC becomes a safety concern, and Dean came out to clear a clogged drain, explaining what went wrong instead of leaving her guessing. These scenarios illustrate why 25-year clients like Angie Bobo return to Dean for replacement units and refer friends without hesitation.
