An air conditioning system is not just a luxury during a humid Chicago summer, it is a necessity. When your A/C breaks, you don’t want it to take 3-5 business days for someone to come out to repair it. At McNally’s Heating & Cooling we provide 24-hour emergency services to make sure you and your family are staying cool and comfortable.

The efficiency of your A/C system will ultimately depend on proper installation. If anything is loose or connected improperly, it could lead to costly energy bills and damage to the A/C system. At McNally’s Heating & Cooling, we will guide you through the process and send out a professional from our team to ensure everything is installed and running as efficiently as possible.

No matter what type of system you have or what issue you’re facing with it – we can help! At McNally’s Heating & Cooling, we provide 24/7 AC repair service 365 days a year from our experienced technicians.

A properly maintained air conditioner is essential in preventing inconvenient breakdowns and in lowering utility costs. 

Air Conditioning Replacement

When it’s time for a new central air conditioner, you’ll probably have a lot of HVAC questions. The air conditioning installation and service specialists at McNally’s Heating and Cooling are waiting to help you. In helping you to select the best new ac system for your home or business, we need to understand the problems with your old unit, your goals for energy efficiency and indoor air quality, and your budget.

Air Conditioning Recharge

Another reason your A/C may not be cooling properly is that it needs a recharge. Recharging is one of the most affordable ways to improve the efficiency of your A/C System. An A/C recharge involves refilling the refrigerant inside the HVAC system. It’s important to maintain proper levels of refrigerant to keep you cool and to avoid costly energy bills from overworking your system. Contact us today to schedule a recharge. 

Coil Cleaning

If you find that your A/C isn’t cooling as well as it used to, you might need your coils cleaned. To ensure this is done properly, have a professional come out and clean your indoor and outdoor coils. They can also clear out any clogs that may be happening due to debris in the coils. 

Coil Replacement

If your A/C system is very old, cleaning the coils may not be enough. You might consider replacing the coils entirely to improve efficiency. Older coils will probably need to be cleaned more often and can be damaged easily. They can also be the cause of higher energy bills. Contact us to see if replacing your coils is the best option for you.

Repeat customer. Got a new HVAC/AC unit two years ago, and when we needed to change our first floor unit, I only called McNallys. Russ has worked with us both times. He is great and I would recommend!

Angel was polite, professional and efficient. Even though I called at the last minute, Angel came to the rescue. He cleaned my furnace. And gradually, it went from 60 degrees to 70 degrees. Angel is an asset to your company. He was fantastic. Thanks to all of you for helping me with my "heating" issue. You guys are the best. I will be using you in the future.

McNally's is the best! They installed my AC unit last summer and today they came to do a maintenance check on my furnace. The technician Brenden was great! He was very thorough and checked that everything was working as it should be. I renewed my maintenance agreement without hesitation because I will not go anywhere else now that I've seen the care that McNally's takes of their customers.

We needed a new furnace due to a crack in our furnaces heat exchanger. We went Costco and learned about McNally's. It was a no-brainer.. No one can beat McNally's and they offer solid customer Service from Sales to Installation to Service.

Furnace went out Friday after Thanksgiving. Brendon fixed us up that night after a looong day.

Recently during our annual tune-up, Esteban quickly noticed a crack that was emitting CO. Our furnace is only 6 years old so this unexpected issue caught us off guard. The entire McNallys team was extremely patient and explanatory as they helped us work through the issue. We ultimately decided to replace and upgrade our current system with a better one, and within four days, our new system was properly installed and working. The installation team was neat and efficient, I was so pleased. Thank you to Russ for helping us with the financial paperwork and rebates, he came to our home twice to make sure everything was in order, despite it being a holiday week. We look forward to continued work with McNallys and highly recommend them to anyone in the area.
