Furnace Solutions from McNally’s

Without your furnace, what would you do on those chilly Chicago nights? Once you have your furnace installed, it’s important to keep up with routine maintenance. At McNally’s Heating & Cooling, we understand that you’re busy. The last thing on your mind during the summer is making sure your furnace is in working order for the winter.
McNally’s has been working with furnaces for over 50 years, and we’ve seen it all. Let our team of licensed professionals help you with all your furnace needs, including:
  • New Furnace Estimates and Sales
  • Furnace Installation

If you’re looking to replace an outdated furnace, the team at McNally’s can help. Hanging onto an old furnace can increase your risk of emergency repairs, and can cost you more on your energy bill. That old furnace is probably not distributing heat the way it used to, and purchasing a new furnace can increase efficiency.
Making the switch to a high-efficiency furnace from the one that came installed in your house is a big deal. It will definitely save you on energy costs, and proper maintenance should take less upkeep. The number of options can be overwhelming, and the team at McNally’s is here to help.
Purchasing a new furnace is a big investment, and our team of professionals can point you in the right direction. Contact McNally’s today and we’d be happy to answer any questions you have about buying a new furnace and give you an estimate.

Furnace Installation

After your purchase, the job’s not over until the furnace is installed. Furnace installation is complicated, which is why our technicians are licensed and trained before they’re allowed to work. You might think you’re saving money by trying to install it yourself, but trust us, you want McNally’s to help. We will ensure everything is working efficiently to keep you warm on those below-freezing nights.

Furnace Repair

When your furnace breaks, not only will you be cold, but it can cause further damage to the rest of your heating system. Pipes and ductwork can become damaged if heat isn’t flowing properly. Our team of professionals has been working on furnaces for over 50 years, and there’s nothing they haven’t seen. Contact our team today to schedule furnace repair to get you warm and toasty again.

24/7/365 Emergency Furnace Repair

Waking up to realize you need a furnace repair at 3:00 am is never fun. That’s why McNally’s offers 24/7/365 emergency furnace repair services. No matter what time of day, our team is on-call and ready to get your furnace in working order.

Routine Furnace Maintenance

Before the winter months set in, it’s important to schedule your routine furnace maintenance with McNally’s. It can be easy to forget about your furnace when it’s warm out, but your furnace can still experience wear and tear when not in use.
Looking at your furnace with an untrained eye could mean you miss something a professional could catch early. This could land you with costly emergency repairs, or a premature entire furnace replacement. Hiring the team at McNally’s for routine maintenance will keep your furnace in tip-top shape from cleaning to coil replacements.

Ductwork

Without ductwork, your furnace won’t be able to deliver warm air to the rest of your house. That’s why McNally’s offers ductwork services along with furnace repair and maintenance. Ductwork is usually hidden from view, so you won’t see it if there are cracks and breaks causing leaks. It’s important to have your ductwork looked at when your furnace doesn’t seem to be working properly to rule it out as an issue.
Repair or replace? ENERGY STAR recommends replacing AC units older than 10 years and furnaces older than 15 years.
