5 Signs Your AC Needs To Be Replaced

Wondering if it’s better to keep repairing your old air conditioner or finally replace it? Here are five clear signs it’s time to invest in a new AC system for better comfort and efficiency:

If you notice one or more of these signs, talk to Capital’s cooling experts. We’ll help you choose the right system for your home and budget — with honest estimates and no unnecessary upsells.

Central Air Conditioning Installation

We install central AC systems every day throughout Milwaukee and the surrounding suburbs. Most homeowners come to us for one of three reasons:

• New Installation – Adding central air to a home that’s never had it before, such as a new build or an older house without existing cooling.
• Replacement of an Old Unit – Swapping out an aging, inefficient system to improve comfort and reduce energy costs.
• Emergency Replacement – Installing a new system quickly after the old one fails beyond repair.

When you call Capital for air conditioning installation, you get more than just a quick swap — you get a properly engineered cooling solution tailored to your home for lasting comfort, efficiency, and value. We’ll evaluate your needs, explain all your options, and provide a straightforward, transparent price before work begins.

Other AC Systems We Install

Ductless Mini-Splits
Ideal for homes without existing ductwork, older houses, or room additions, ductless mini-splits provide cooling (and in many models, heating) without the need for large-scale renovations. They use a compact indoor unit connected to an outdoor condenser, allowing you to control temperatures in individual rooms for maximum comfort and efficiency.

Heat Pumps
A heat pump works as both an air conditioner and a heater, moving heat in or out of your home depending on the season. In summer, it cools just like a central AC; in cooler months, it can efficiently heat your home — even in Wisconsin’s shoulder seasons. Modern cold-climate heat pumps can handle much of our winter weather, making them a smart choice for reducing reliance on a furnace.

Zoned Control Systems
A zoned HVAC system allows you to set different temperatures in separate areas of your home. This is ideal for multi-story houses, homes with large temperature variations between rooms, or households where comfort preferences differ. Zoning improves comfort and helps cut energy waste by conditioning only the spaces you use.

Unico Small-Duct Systems
For homes with limited space for conventional ductwork — such as historic Milwaukee houses — a Unico system delivers quiet, draft-free cooling through flexible, small-diameter ducts that can be routed through walls and ceilings with minimal disruption to your home’s structure.

What to Expect When You Choose Capital

Your Capital installer will:

Inspect your whole system — not just the unit, but your ductwork, insulation, and airflow, so nothing holds back performance.

Perform a professional load calculation to match your home’s exact cooling needs. This prevents buying an oversized or undersized system, which can cause higher bills and uneven temperatures.

Explain your options clearly, including SEER ratings, energy efficiency rebates, and features like variable-speed compressors or smart thermostats.

Give you a transparent, upfront price with no surprises — and help you understand financing options if needed.

Our Meticulous Installation Process

Capital installs all major AC brands and models. Here’s how we ensure it’s done right:

• Custom-build and seal ductwork as needed to ensure balanced airflow to every room.
• Fine-tune your new system so it runs at peak efficiency, saving you money year after year.
• Test every component — refrigerant levels, thermostat calibration, and airflow — before we leave, so you know it’s perfect from day one.
• Review the new system with you, answer all your questions, and show you how to use your new thermostat and any smart features.

How Much Does a New Air Conditioner Cost?

When it comes to how much it costs for an air conditioner installed, 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:

1. Equipment size
2. Energy Efficiency
3. Caliber of HVAC company you choose to work with
4. 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
