- DDDannyGAug 14, 20265.0We recently moved to Cecil county and needed a HVAC company. Went off the Google reviews and chose this company. It was the right decision. The guys came out today to fix my malfunctioning unit. Did that and more. Can’t say enough about that and this is my go -to HVAC company going forward.
- MCM M ClassAug 14, 20265.0After having a power surge, and knocking out my AC units. They ordered parts and replaced them and had my AC back up and running. Great communication. Arrived on time very good service
- DBDiana BrewerAug 4, 20265.0We got up Friday morning and realized the AC wasn’t producing cool air. I panicked because I dropped the ball getting our service done. I called the office and scheduled an appointment for Tuesday. They then called back saying they had a tech in the area and he could come by after his last appt. He arrived earlier than expected and was able to evaluate and fix the problem in under an hour. We were very appreciative.
- RMRay MastnjakAug 4, 20265.0Hunter did a great job ... he was very professional, explained what he needed to do, and was very patient with our questions. Thank you Cullum HVAC, great experience!
- CPChristopher PippinJul 27, 20265.0Ethen Oakley was kind and knowledgeable. I called at 7:30am they were at my house by 7:55am and had diagnosed and fixed my ac system and as little as 20 minutes. Thank you for the quick response.
