Gregg Heating & Air Conditioning

Gregg Heating & Air Conditioning operates as a full-service HVAC contractor serving New Berlin, Wisconsin and surrounding communities with a 4.9-star average rating drawn from 86 client reviews. The company maintains around-the-clock availability seven days each week, enabling technicians to respond to heating and cooling emergencies regardless of when they occur. Residential clients in New Berlin and nearby municipalities can access the full spectrum of climate control services, from routine seasonal maintenance to complete system replacements. The business functions as a single-point provider for diverse indoor comfort needs, eliminating the necessity for homeowners to coordinate multiple contractors when both heating and cooling equipment require attention.

The contractor distinguishes itself through indoor air quality specializations that extend beyond standard temperature control.

The company also provides heat pump installations and boiler systems, expanding service capabilities beyond conventional forced-air furnaces and split AC units. This breadth enables homeowners to select equipment configurations tailored to specific comfort requirements and architectural constraints.

Technician Kyle received repeated commendation across multiple reviews for communication clarity, arriving at homes within promised timeframes and updating clients regarding arrival windows. Another reviewer documented a 15-year service relationship highlighting the company's willingness to identify and correct foundational installation flaws that previous contractors missed, adding an electronic air cleaning system with UV lights to address allergy-related concerns.
