Gregg Heating & Air Conditioning

Gregg Heating & Air Conditioning has kept New Berlin comfortable since 1974, when Greg Hausinger founded the company. Kyle Geisberger, the current owner, bought the business in 2017 after learning the trade from the ground up starting in 2001. The company holds an A+ rating from the Better Business Bureau and has earned 4.9 stars across 85 verified Google reviews. Serving New Berlin, Waukesha, Wauwatosa, and the broader Milwaukee metropolitan area, this locally owned contractor handles everything from quick AC repairs to complete furnace replacements and boiler system installations.

What distinguishes Gregg Heating is their commitment to doing every job correctly on the first attempt, a philosophy written plainly on their website. They are an authorized Lennox dealer, offering everything from residential split systems to high-efficiency heat pumps. Their indoor air quality division includes AprilAire whole-house humidifiers, electronic air cleaners, and UV light systems that address allergens, pet dander, and airborne contaminants typical of Wisconsin winters. The company provides flexible financing options and annual maintenance plans, making system replacements more accessible for budget-conscious homeowners.

Customer reviews repeatedly mention owner Kyle Geisberger responding to emergency calls personally. During a July heat wave, one reviewer's AC failed completely, and Kyle arrived at their home within an hour, diagnosing multiple failures and restoring cooling the same day. Another reviewer described Kyle rearranged his schedule on a weekend to restore heating for a family with young children after their furnace failed. Technicians have installed boiler systems in homes with existing hot water heat, a more complex retrofit that other contractors declined. Reviews also note the crew uses protective coverings to prevent flooring damage during equipment installs, a detail that resonates with homeowners who have invested in finishes.
