3 Questions to Ask Before You Buy a New AC for Your Wisconsin Home

If your old AC is struggling or has called it quits, the decision to buy a new unit might seem straightforward.

However, for homeowners in Mukwonago, Muskego, Wales, and surrounding communities, making the right choice requires a bit of homework.

Midwest Heating & Cooling has over 20 years of experience serving homeowners and businesses. We believe in empowering our customers with the knowledge to make informed decisions. Before you make this significant investment in your home, here are three crucial questions to ask:

1. What About Energy Efficiency?
2. Is the AC System Properly Sized?
3. What Does Your Company Offer After the Install?

1. What About Energy Efficiency? Understanding AC System Types

One of the most critical factors influencing your decision should be the energy efficiency of the new AC system. An energy-efficient unit can drastically reduce your monthly utility bills and lessen your environmental footprint.

Beyond the SEER2 (Seasonal Energy Efficiency Ratio 2) rating, the type of compressor technology plays a significant role in how efficiently your system operates:

• Single-Stage AC Systems: These are the most basic and typically the least expensive option. A single-stage compressor operates at full capacity whenever it’s running—either “on” or “off.” While they get the job done, they can lead to less consistent temperatures and higher energy consumption due to constant cycling between full power and no power.
  
• Two-Stage AC Systems: A step up in efficiency and comfort, two-stage systems offer more flexibility. Their compressors can operate at two different capacities, typically around 70% for milder days and 100% for hotter periods. This allows the system to run for longer cycles at a lower, more efficient speed, leading to better dehumidification, more consistent temperatures, and quieter operation.
  
• Variable-Speed AC Systems: Variable-speed compressors can adjust their output incrementally, often in very small percentages, to precisely match your home’s cooling needs. They can operate at hundreds of different speeds. This allows for near-constant operation at the lowest possible setting required to maintain your desired temperature. While the upfront cost is higher, the long-term energy savings and enhanced comfort often make them a worthwhile investment.

When speaking with our HVAC professionals at Midwest Heating & Cooling, always ask about the SEER2 rating and the differences between these technologies. A reputable company will explain how each option aligns with your specific needs and budget, helping you achieve optimal comfort and savings.

2. Is the AC System Properly Sized for My Home?

This question is arguably the most critical. Many homeowners unknowingly end up with an air conditioning unit that is either too large or too small for their living space, leading to a host of problems.

Unfortunately, it’s a common industry oversight where some companies sell homeowners oversized units. While it might seem like a bigger unit would cool your home faster and more effectively, the reality is often the opposite.

An oversized AC unit will “short cycle.” This means it cools the space too quickly, shuts off before it can properly dehumidify the air, and then turns back on shortly after.

This constant on-off cycling is highly inefficient, puts undue strain on the system’s components (leading to premature wear and tear), and results in uncomfortable humidity levels within your home.

Conversely, an undersized unit will struggle to cool your home adequately, running constantly without ever reaching the desired temperature, leading to high energy bills and insufficient comfort.

At Midwest Heating & Cooling, we emphasize precision. We don’t guess; we use the Manual J calculation for accurate sizing. Manual J is an industry-standard methodology developed by the Air Conditioning Contractors of America (ACCA).

It’s a comprehensive, scientific approach that considers various factors unique to your home, including:

• Square footage and ceiling height.
• Window types and orientation (heat gain).
• Insulation levels.
• Number of occupants.
• Appliance heat generation.
• Local climate data specific to Wisconsin.

By performing a thorough Manual J calculation, our experts ensure that your new AC system is perfectly matched to your home’s unique cooling load.

3. What Does Your Company Offer After the AC Install?

The relationship with your HVAC company shouldn’t end once the new AC unit is installed. A truly reputable company will stand by its work and offer ongoing support to ensure your system continues to perform optimally for years to come.

This is where Midwest Heating & Cooling truly differentiates itself.

We don’t just install equipment; we aim to build lasting customer relationships that endure for the entire life of your HVAC system.

Here are the key questions to ask regarding post-installation support:

What Type of HVAC Warranty Do You Offer?

• Most new AC units come with a manufacturer’s warranty covering parts. The duration can vary, typically from 5 to 10 years, and often requires professional installation and annual maintenance to remain valid.
  
  A good HVAC company will also offer a labor warranty on their installation work, covering any issues arising directly from the installation process. Midwest Heating & Cooling provides peace of mind with robust warranties, ensuring that both the equipment and our workmanship are protected. Always clarify the terms and duration of both parts and labor warranties.

What Does Your HVAC Maintenance Plan Include?

• Regular maintenance is the cornerstone of a long-lasting, efficient AC system. Just like your car, your HVAC system needs routine tune-ups to perform its best and avoid unexpected breakdowns.
  Midwest Heating & Cooling offers tailored maintenance plans designed to maximize your system’s efficiency, extend its lifespan, and provide preferential service and discounts to plan members. Regular maintenance helps prevent costly repairs and ensures your warranty remains valid.

What Type of HVAC Financing Do You Offer?

• Ask about financing options https://midwesthvacpro.com/financing/ that can make the purchase more manageable. Midwest Heating & Cooling understands this and partners with reputable financing providers to offer various plans with approved credit, allowing you to enjoy immediate comfort without financial strain.

We aim to make quality HVAC solutions accessible to all our Mukwonago, Muskego, and Wales neighbors.
