What the R-22 Freon Ban Means for You

Blog | Cardinal Heating and Cooling | HVAC Installation and Support

If you live in the Chicagoland area, you’ve probably heard about the upcoming ban on R-22, or the refrigerant more commonly known as Freon. Following January 1, 2020, the production and importation of Freon will become illegal in the U.S.

Historically, Freon has been utilized across the world for a number of different products with cooling properties, including refrigerators and air conditioners. Because the chemical component has ozone-damaging properties, the Environmental Protection Agency (EPA) has taken action to prevent its use in the U.S.

Most HVAC professionals have been phasing out Freon from customers’ homes over the past several years, including Cardinal Heating and Cooling. Many of our customers will not be affected by the Freon ban. However, if you own an air conditioner that is over ten years old, you may be at risk when the law goes into effect.

Why Your Air Conditioner is Leaking Water Inside Your Home

Anytime there’s a leak in your home, it’s natural to feel concerned. Water damage can be expensive to repair, and it doesn’t take long to occur once a leak has started. Even the simplest leak can damage floors, walls, ceilings, carpet, and even furniture.
If your A/C has started leaking water, it’s crucial to take action. Before we go any further, turn off your air conditioner and clean up the water that dripped out of it. Water damage can occur within minutes of a leak, and you’ll want to protect your home from any potential damage while you investigate the cause of the leak.


While a leaky A/C is a cause for alarm, the majority of leak-related malfunctions can be quickly repaired by an HVAC technician.

  • Reason # 1 – Frozen Evaporator Coil
  • Reason # 2 – Clogged Drain Line
  • Reason # 3 – Rusty Drain Pan
  • Reason # 4 – Low Refrigerant 

4 Signs It's Time to Replace Your Air Conditioner

Blog | Cardinal Heating and Cooling | HVAC Installation and Support

Being a homeowner comes with difficult decisions. While we’ve all heard that investing in a home increases its value, deciding where and how to do that can be a tough choice. Should you update the kitchen? Finish the basement? The answer isn’t always straightforward.
When it comes to your HVAC system, the decision-making process gets even harder. Unless you’re a trained HVAC technician, it can be tough to tell whether a malfunctioning A/C needs new batteries in the thermostat or a more extensive repair. For homeowners with older air conditioners, the decision often become whether to repair the unit or replace it entirely.
Choosing to replace your old A/C is an important decision. Modern air conditioners can last upwards of fifteen years, so it’s crucial you choose the correct unit for your home’s cooling needs. It’s not a decision that should be rushed. But if your older A/C breaks down on a 100 degree day, you might not have a choice. You’ll have to make a quick decision.


Much like an old car, air conditioners show signs of failure before they actually fail. By paying attention to the performance of your older A/C, you can start preparing for the purchase of a new unit before you need it. Here are the top four signs your A/C is nearing the end of its life.

  • Your Air Conditioner is more than ten years old
  • Your Air conditioner frequently breaks down
  • Your energy bills keep going up
  • Your A/C uses R-22 Freon

4 Reasons Why Your A/C Isn’t Working

Blog | Cardinal Heating and Cooling | HVAC Installation and Support

Air conditioners are amazing inventions. Created in 1902 to control the humidity level in a printing press, the modern day A/C has become a common household amenity. In today’s world, it’s rare to find a home or office building that doesn’t have some type of air conditioning. Metro Detroit residents in particular know that a day without air conditioning in the hot Midwest sun can be tough.


While air conditioners are amazing, it’s important to remember they are just like any other piece of mechanical equipment. Just like a toaster, cell phone, or car, your A/C can break down. They’re not indestructible. An A/C is composed of many working parts, and it requires all of them to keep your home comfortable and cool. If a single part malfunctions, the entire A/C could stop working until the problem is resolved.


Over the years, we’ve dealt with hundreds of malfunctioning air conditioners. We’ve discovered that many A/C units encounter the same problems. If you woke up to a broken A/C and a 90 degree day outside, don’t fret just yet! The solution may be simpler than you think.

  • Your Thermostat is not working
  • Change your filter
  • Clean your condensor
  • Check your evaporator coil
