Five Questions to Ask, Before It Hits 90°F in Wisconsin

Be prepared for your first AC stress test

By: | July 11, 2017 6:35 pm

Did you know, across the last 30 years, on average, central Wisconsin has 10 days of 90° F or greater temperatures?

Your central air conditioning probably started doing its thing to maintain comfort and maybe pull some moisture out of your residence or workplace when temps hit the upper 70s. But hotter temps can strain the cooling performance of your AC. So before the next heat wave, consider the health of your cooling system. Here are five questions to contemplate each year before things really heat up.

#1 How old is your Central Air Conditioning?
You probably know when your house was built. But it can be hard to remember when major components and appliances were replaced. It’s surprising how AC units from the 1980s seem to keep chugging along. The National Association of Home Builders will tell you that the average AC unit has a 10-15 year lifespan. That longer range is dependent on regular maintenance.

Here’s another factor to consider. Most any AC unit built before 2010 uses R-22 Freon refrigerant which if depleted because of leaks, is expensive to replace. New EPA regulations are phasing out R-22 because of its ozone- threatening gases. Since 2010 new R410 Puron refrigerant has been mandated. It’s more environmentally responsible. Plus it is better at absorbing and releasing heat, so it’s more effective which helps your system run more efficiently, saving energy use and money.

#2 How leaky is your home?
Surprising to many homeowners, the Department of Energy reports that insulation can settle over time, leaving areas like walls and ceilings of your home exposed. Enough small leaks and under insulated spots throughout your home can be like leaving a window open, all year long. You could call it the open window effect.

In fact, research from the 2015 North American Insulation Manufacturers Association (NAIMA) tells us up to 90% of existing US single family homes are under insulated. Most of us only think about home insulation issues when the temperature plummets in the winter. However, that hot summer air is also trying to find a way into your home each summer which affects your comfort.

#3 How comfortable are you?
If your AC is under performing, you are probably missing out on the whole-home comfort you should be enjoying. Also remember, your furnace actually distributes that cool AC air. So your furnace fan should be checked and your filter replaced at least twice a year. If you have pets or allergies, replace that filter every 60 days.

#4 What is your summer looking like? 

The demands you put on your home can vary throughout the year. Summer is more common for hosting out-of -town guests, friends or relatives. To make your home inviting for these times, you need to have a comfortable place to gather. So if your home is struggling before summer guests, imagine what all those extra bodies will do.

#5 Do you like to save money?
Focus on Energy provides rebates ranging from $75 to $2,250 depending on the improvements. Xcel Energy will provide an additional incentive equal to 80% of the Focus on Energy rebate to customers who use natural gas or electricity for their heat source and are Xcel Energy customers.

Other benefits of having a new central Air Conditioner include:

Quieter operations. Newer, high-tech sound absorbing materials in modern AC systems make for much lower operating noise levels compared to older models, helping assure your AC is felt, yet not intrusive.
No more surprises. As more efficient AC systems minimize on-and-off cycling, they typically require less extreme repairs, when properly maintained.
Peace of mind. You can enjoy your busy summer knowing you are able to have a cool respite from the heat – especially when guests are part of the plan!
