2400 S Commerce Dr, New Berlin, WI 53151Our New Berlin HVAC Services
Mr. Holland’s diagnoses comfort problems, repairs failing equipment, performs seasonal maintenance, and replaces unreliable or inefficient systems. For new installations, we consider the property’s layout, insulation, ductwork, fuel source, electrical capacity, and year-round heating and cooling demand.
Heating
When a furnace blows cool air, a boiler leaves rooms cold, or heating costs randomly increase, the system needs more than a quick adjustment. Our heating services include furnace and boiler repair, maintenance, replacement, and installation. We test the equipment and supporting components to diagnose the problem and find the solution.
Cooling & Air Conditioning
Mr. Holland’s repairs, maintains, and replaces central air conditioners and ductless cooling systems in New Berlin. We address refrigerant-cycle problems, frozen coils, drainage issues, airflow restrictions, electrical failures, and equipment that can’t keep up with the home.
Ventalation & Air Quality
Uneven airflow, excess dust, stale rooms, and indoor humidity problems can originate outside the heating or cooling equipment. Our team evaluates ductwork, filtration, ventilation, humidification, dehumidification, and other indoor air quality options to solve your home’s specific issues.
Heat Pumps
Heat pumps provide cooling and heating through the same system, but Wisconsin installations must account for low outdoor temperatures. We install, repair, and maintain ducted and ductless heat pumps, including systems designed for cold-weather operation.
Commercial HVAC
Commercial heating and cooling requirements depend on occupancy, operating hours, equipment loads, ventilation, and how the space is used. Mr. Holland’s provides commercial HVAC repair, maintenance, replacement, and installation for New Berlin businesses. We restore dependable operation while planning service around the needs of your property.

HVAC breakdowns don’t follow business hours. Mr. Holland’s provides 24/7 emergency HVAC service in New Berlin, with technicians available to diagnose urgent heating and cooling failures and restore dependable operation. Call anytime your system can’t safely wait for a regular appointment.

A+ for Everything!
Could not ask for a better business to work with. From replacing my sewer stack to inevitably having to replace my main sewer line, they gave 100%. Took their time to explain each step and did the job correctly. And to make them even better, they came out.
Mr. Holland’s is It!
Our AC took a dive on the hottest week of the summer. They were able to get in after a few days and have a whole new system installed and running perfectly! With our old system being from 95’, it was time we invested.
Highly Recommend
The technician who came to service my home was Shannon, and he was absolutely the best. I wish I could give him a million stars. He knew exactly what to do with minimum effort. If I have any issues again in the future, I’m definitely going to request him.
Knowledgeable & Straightforward
Mr. Holland’s laid out the options for our boiler, which is 25 years old. Left everything in good order and was very pleasant. Couldn’t be happier!
Absolutely 5 Stars – I’d Give Them 10 If I Could
Kyle came out yesterday to fix our air conditioner, and he was a godsend! It’s blistering hot and humid today. Turned out to be a fried wire in the control panel. We’re cool & so comfortable today, and the bill was exceptionally reasonable.
Great Work Paul, and Thank You Mr Hollands!
Mr Hollands came through in a pinch, and we couldn’t be more pleased with the prompt scheduling and service by our technician, Paul Johnson. This is our first experience with Mr Hollands, and they’ve definitely earned our business in the future.







Types of HVAC Systems We Service

HVAC Problems To Look Out For
Heating and cooling equipment often shows signs of trouble before it stops completely. Changes in temperature, airflow, sound, operating time, or energy use can help identify a problem while the system is still running.
Heating System Issues
- Heating costs rise quickly: Longer run times or increased fuel use can indicate declining performance, deferred maintenance, or changes elsewhere in the home.
- The furnace starts and stops: Short cycling can be caused by restricted airflow, control trouble, overheating, or equipment that is operating within normal limits.
- Some rooms remain cold: Uneven heating can point to duct leakage, balancing problems, poor circulation, thermostat placement, or an issue with the heating system.
- Cold or weak air from vents: Can be caused by the burner, heat exchanger, blower, filter, ductwork, or another component affecting heat production or airflow.
- New noises from boiler or furnace: Banging, grinding, rattling, whistling, and repeated ignition sounds should be investigated before the problem gets worse.
Air Conditioning Issues
- Cooling varies from room to room: Duct design, insulation, sun exposure, closed dampers, or equipment capacity may be contributing to the imbalance.
- System runs but doesn’t cool: Warm supply air may result from a refrigerant problem, failed compressor component, dirty coil, thermostat issue, or loss of power to part of the system.
- Ice forms on equipment or the refrigerant line: Freezing commonly involves restricted airflow or a refrigerant-side problem and shouldn’t be treated by just removing the ice.
- Water collects around the indoor unit: A blocked condensate drain, damaged pan, frozen coil, or failed pump can allow moisture to escape.
- The house feels humid despite the AC running: Oversized equipment, short cycling, low airflow, or poor system performance can reduce moisture removal.
General HVAC Warning Signs
- Repairs are becoming more frequent: Repeated failures can make replacement worth comparing with the cost and expected life of another repair.
- Thermostat and room temperature don’t match: The thermostat may be misreading conditions, placed poorly, or unable to communicate correctly with the equipment.
- System runs longer than it used to: Extended cycles can indicate a maintenance issue, loss of capacity, duct leakage, or a change in the building’s heating or cooling load.
- Unusual smells come through vents: Musty, electrical, burning, or fuel odors require different responses and shouldn’t be ignored.
- Energy use increases for no reason: A sudden change may reflect equipment trouble, airflow restrictions, control problems, or declining efficiency.
Local Considerations When Choosing a New HVAC System
An HVAC replacement should be selected for the property, not matched automatically to the capacity of the old unit. New Berlin’s climate, housing stock, utility rates, and permit requirements all affect equipment choice and installation planning.
Climate Factors
New Berlin Data
HVAC Impact
Cold Weather Heating Demand
Local climate normals show a months-long heating season with sustained periods of time below freezing. (National Weather Service)
Heating capacity must be based on a load calculation. Heat pumps should be compared by low-temperature output, not only their nominal rating.
Summer Cooling & Humidity
Typical mid-July conditions near New Berlin reach the low 80s during the day and mid-60s at night, with humidity adding to the cooling load. (National Weather Service)
Correct sizing helps the air conditioner run long enough to remove moisture without sacrificing temperature control.
Snowfall & Outdoor Unit Exposure
The greater Milwaukee area average is 48.7 inches of snow per year. (National Weather Service)
Heat pumps and condensing-unit locations need drainage, airflow, service access, and protection from snow accumulation and roof runoff.
Home Size & Housing Stock
New Berlin has 17,064 households averaging 2.35 people, and 76.5% of occupied homes are owner-occupied. (US Census Bureau)
Household count alone can’t determine system size. Square footage, ceiling height, insulation, window area, layout, and actual usage have to be considered.
Home Age & Construction Mix
The New Berlin housing-plan inventory reported a median build year of 1973, with about 66% of homes built from 1940 through 1989. (City of New Berlin Housing Plan)
Older homes may need duct, insulation, venting, or electrical corrections, while tighter newer homes may require closer attention to controlled ventilation.
Electricity Rates & Energy Costs
The 2026 We Energies standard residential energy charge is listed at 19.342 cents per kWh before fuel and environmental adjustments. (We Energies 2026 Rates)
Efficiency ratings, fuel type, expected run time, and heat pump performance should be compared by estimated annual operating cost, as well as purchase price.
Permits & Local Regulations
New Berlin lists permits for new and replacement furnaces and air conditioners, with electrical permits also required for these projects. (City of New Berlin)
The project schedule and estimate should account for permit applications, required inspections, equipment clearances, and current installation codes.

Common HVAC Questions
How often should I schedule HVAC maintenance?
Most homes benefit from one heating visit and one cooling visit each year. Scheduling service before the system’s busiest season gives a technician time to check operation, airflow, electrical components, and signs of wear.
What are common signs that an HVAC system needs repair?
Call for HVAC service if you notice weak airflow, uneven temperatures, unfamiliar noises, new odors, short cycling, or a sudden increase in energy use. A system that won’t start or can’t maintain a safe indoor temperature may require emergency service.
Do heat pumps work in Southeast Wisconsin?
Yes, many modern heat pumps can provide efficient heating and cooling in Wisconsin. The right setup depends on the home and the equipment, and some properties may benefit from a backup heat source during the coldest weather. We’ll review those details before recommending a system.
Why is the air coming out of my vents weak?
Weak airflow may come from a dirty filter, a blower problem, buildup inside the system, damaged ductwork, or closed and obstructed vents. Because several issues can cause the same symptom, a technician should inspect the system before parts are replaced.
