Cooling Systems We Install & Service
Central AC Systems
Traditional AC systems have several advantages over other cooling options:
1
Designed to cool the entire house evenly so every room is comfortable, regardless of its location or size.
2
Consume less electricity to cool a larger area, which can result in lower energy bills.
3
Generally quieter than other types of air conditioners because the compressor is located outside the house.
4
Do not require any bulky or unsightly units to be placed in windows or rooms.
5
Helps to filter out dust, dirt, and allergens, improving the air quality inside the house.
6
The thermostat can be used to control the temperature in the entire house, making it easy to adjust the temperature to your desired level.
When Capital installs a central air system, we always test the airflow through your ductwork to make sure you have even cooling throughout your house.
Ductless AC (Mini-Splits)
On the other hand, ductless air conditioning systems (also known as mini-splits) have some advantages over traditional AC systems:
1
Designed to be flexible and can be installed in a variety of settings, including some settings where a central air system won’t work.
2
They use even less energy than traditional systems because they do not require ductwork, which can cause energy loss due to leaks and inefficiencies.
3
Cool different areas of the house independently for greater control over the temperature in different rooms, which can result in energy savings.
4
Easy to install, requiring only a small hole in the wall for the refrigerant lines and electrical wiring, which is ideal for homes where ductwork is not practical or where installation is difficult.
5
Designed to be sleek and unobtrusive. The indoor units can be mounted on walls or ceilings and are available in a variety of styles and colors to match any decor.
Heat Pumps
Heat pumps are unique in a number of ways:
1
Highly energy-efficient, as they do not generate heat but rather move heat from one place to another.
2
Dual functionality, providing both cooling and heating.
3
More environmentally friendly for air conditioning because they do not burn fossil fuels or emit greenhouse gasses.
4
Designed to maintain a consistent temperature throughout the house, eliminating hot and cold spots.
5
Require less maintenance than traditional air conditioning systems because they have fewer moving parts.

How much does a new air conditioner cost?
When it comes to how much it costs for a new air conditioner, there’s a boat load of conflicting answers out there: Home Advisor says $7,200-$10,500, Back Alley Bob says $1,800 if he can crash on your couch, your neighbors said they paid $1,500 in 1970 and Improve.net says $5,500-$10,000. Not helpful.
Asking how much an air conditioning system costs is pretty much like asking how much a car costs. Are you buying a BMW or a Ford Fiesta? A4 cylinder or a V8? Are low monthly payments or reliability most important? And the list goes on… HVAC isn’t much different except the main factors that impact the cost of a new air conditioner include:
- Equipment size
- Energy Efficiency
- Caliber of HVAC company you choose to work with
- Financing, tax credits & available rebates
So, as a homeowner with a lot of information at your fingertips it’s important to remember the new car analogy when your start to read about the “national averages” or “a typical price ranges.” The best way to find out what if would cost to get a new air conditioner installed is talk with one of our comfort advisers. Capital consultations are free and last roughly 90 minutes.

Cooling Services FAQs
What cooling services do you provide?
Capital Heating & Cooling provides complete cooling services, including air conditioning repair, maintenance and tune-ups, system replacement, and new AC installation. We work on all major cooling system types used in Wisconsin homes.
Do you repair and service all types of air conditioning systems?
Yes. We service central air conditioners, heat pumps, ductless mini-split systems, zoned cooling systems, and high-efficiency AC units. Our technicians work on both newer equipment and older systems commonly found in the area.
How do I know whether I need AC repair or replacement?
If your system is newer and the issue is isolated, repair is often the right choice. If your AC is older, requires frequent service, or struggles during hot weather, replacement may provide better long-term comfort and efficiency. We’ll explain your options clearly.
Do you offer preventive AC maintenance and tune-ups?
Yes. Routine maintenance helps reduce breakdowns, improve efficiency, and extend the life of your air conditioner. Tune-ups are especially important before peak summer heat arrives.
How quickly can you respond to cooling service calls?
We offer fast response times throughout the Greater Milwaukee area, with same-day service available whenever possible. During extreme heat, no-cooling situations are prioritized.
What brands of air conditioners do you service?
We service and repair all major air conditioning brands. Our technicians receive ongoing training to stay current with evolving system technology and efficiency standards.
Do you provide cooling services throughout Milwaukee and nearby suburbs?
Yes. We provide cooling services throughout Milwaukee and surrounding communities, including Wauwatosa, West Allis, Brookfield, Menomonee Falls, and nearby areas.
How does Milwaukee’s summer weather affect air conditioners?
High humidity and prolonged heat waves common in southeastern Wisconsin can put extra strain on cooling systems, causing longer run times and exposing airflow or efficiency issues.
Do you service cooling systems in older Milwaukee homes?
Absolutely. Many local homes were built decades ago and may have older ductwork, electrical limitations, or legacy systems. We regularly service cooling equipment in older homes and adjust recommendations accordingly.
Do you service homes near Lake Michigan or high-humidity areas?
Yes. Homes closer to the lake or in lower-lying areas often experience higher humidity levels. We service and optimize cooling systems to improve moisture control as well as temperature comfort.
Why does my AC struggle during extreme heat waves?
During peak heat, an air conditioner may struggle if it’s undersized, low on refrigerant, or dealing with restricted airflow. These issues often show up during the hottest days and can usually be addressed with professional service.
Can older ductwork affect cooling performance?
Yes. Aging or poorly designed duct systems can restrict airflow, leak cooled air, and reduce overall comfort. Duct-related issues are common in older homes and can significantly impact AC performance.
Is it worth scheduling AC service before summer starts?
Definitely. Pre-season maintenance helps catch small problems early and ensures your system is ready to handle hot, humid weather without unexpected breakdowns.
Can you help with uneven cooling in two-story or finished-attic homes?
Yes. Uneven cooling is common in multi-level homes. We assess airflow, system capacity, and layout factors to improve comfort throughout the entire home.
