Furnace Repair Palatine & Libertyville

When your system fails, the goal isn’t just to get a repairman out—it’s to get the heat back on. We have optimized our entire service process to minimize the time between your call and a warm house.

We are the preferred choice for furnace repair in Libertyville and Palatine because we come prepared:

  • Inventory Depth:

We don’t believe in making you wait for parts. Our fleet carries an extensive stock of components for all major brands, allowing us to complete most repairs on the spot without a supply house run.

Furnace Installation & Replacement

If your furnace is older than 15 years, it may be costing you more in repairs and wasted energy than it’s worth. We specialize in high-efficiency furnace installation in Palatine and Libertyville, helping you upgrade to a system that runs quieter and costs less to operate.

Reasons our customers choose us for furnace installation and replacement include:

  • Engineered for Your Home:

We don’t guess at sizing. We perform rigorous load calculations based on your specific square footage, windows, and insulation to ensure your newly installed furnace performs perfectly.

  • Exclusive Access:

As a President’s Award winner, we can offer Carrier’s most advanced Infinity® System technology, giving you superior control over your indoor climate.

  • Fabrication Expertise:

A great furnace is useless without good airflow. We inspect and optimize your ductwork connections during installation to prevent static pressure issues.

Furnace Maintenance

The most reliable furnace is the one that gets checked before the first snow falls. Our furnace maintenance program is your best defense against unexpected failures. During our visits for furnace tune-ups, we go beyond simple filter changes, performing:

  • Safety Verification:

We rigorously test the heat exchanger for stress cracks to prevent carbon monoxide leaks.

  • Efficiency Calibration:

We clean the burners and adjust the gas valve to ensure you are getting the maximum heat output for your fuel dollar.

  • Electrical Inspection:

We tighten connections and test capacitors to prevent the small electrical faults that cause most mid-winter outages.

What Our Customers
Say About Us

We moved into a new house recently and Allied was recommended to us by my best friend.

We had them install a new humidifier and zone the system. On moving day (Friday) at 3 pm when we showed up we found the AC wouldn't shut off. I texted my tech with hopes of getting on the schedule for the following week since it was late Friday. He said someone would be there in 30 min. They stayed for 2 hours and fixed a faulty wire and it was all covered under warranty. Can't argue with customer service like that. Highly recommend if you want dependable folks that are very responsive.

We were extremely pleased by the service that Allied provided us.

Our A/C went out over the 4th of July we knew we needed a new system installed asap (we knew it was on its last leg). We contacted them and two other companies for comparison quotes. Allied was out here first thing July 5th to assess and provide a quote. In the end we decided to go with them. They were professional, thorough and very detailed in options and quotes.

Moved into the neighborhood and Allied HVAC had been recommended from my brother to replace both our furnace and ac unit.

Very professional from the start with a quote from Chris B. in sales which lead to an install date of my choice. On the day of the installation Jeff and Jackson arrived right on time as requested. The installation was prompt and done in a timely matter, and it they explained exactly what needed to be done from start to finish.
