What Our Clients Are Saying About Us

I called Leith and Jake came out to evaluate my house and make recommendations. He was informative, patient and kind as he sat and explained how the different systems operated. I was impressed with his knowledge base and his ability to use language I could understand in making a good decision for me. I will be highly recommending this team to friends, family and neighbors.

From Jake to Carl to Esteban what a great experience we had getting our new furnace and air conditioner installed. Jake explained in detail all of the appliances and how much everything would cost. Carl and Esteban were two of the most considerate installers we have ever encountered. very knowledgeable. They went above and beyond keeping our house clean. Thank you Leith for your excellent employees.

I remembered my sister used your company and loved your service so I called. Christian was here in less than an hour and worked hard to figure out our complicated heating problem in a hurry. He went above and beyond recognizing some other problems we had been dealing with for a while. Christian just took such good care of us, we will use Leith from now on.

We called Leith at 8AM and spoke to the owner, Brian, who took our relevant information. He was able to send out his service tech, Sean, who was here by 8:45 to do an inspection and to see if it was fixable. He evaluated the situation, provided and explained the merits of the three options. They were prompt, professional, patient with our questions and couldn’t have been nicer. Can’t say enough about the whole team - excellence all around.

We have used Leith for our HVAC checkups for few years. Our system was coming to the end of its life and decided to replace it. Leith was our first and only choice for the job. Esteban and Carl did a thorough and meticulous job on the installation and we were happy with the whole process. I would recommend Leith for their professionalism and ease to work with.

Heating Equipment We Work On for Businesses and Facilities

Commercial heating systems carry heavier loads than home equipment, and no two buildings are set up the same way. Our NATE-certified technicians start every job by learning what heats your space, how it is configured, and how hard it works through an Elgin winter.

Many businesses rely on rooftop packaged units or commercial furnaces, while others heat with boilers, heat pumps, or unit heaters in open work areas. Larger buildings often combine several systems serving separate areas. Whatever your setup, our team evaluates the whole system before recommending commercial heating repair in Elgin, IL, or a full replacement.

Heat delivery depends on more than the equipment itself. Leaky or undersized ducts waste warm air. When the ducts are the problem, we may recommend ductwork repair or replacement in Elgin, IL. Buildings with cold corners and overheated offices can also benefit from HVAC zoning in Elgin, IL.

Commercial Heating Repair and Planned Maintenance to Keep You Running

When the heat goes out in a commercial building, it affects employees, customers, and sometimes equipment or inventory at the same time. Our technicians find the cause, explain what they found in plain terms, and give you the price before starting any commercial heating repair.

Common warning signs include cold air from the vents, uneven temperatures between rooms, short cycling, strange noises, and heating bills that rise without a clear reason. Calling at the first sign of trouble gives our team a chance to fix a small problem before it becomes a building-wide outage.

Northern Illinois winters bring long stretches of freezing weather that keep commercial heating equipment running for hours at a time. Igniters, blower motors, belts, and flame sensors wear faster under that load, and a worn part tends to fail on the coldest days. Replacing it on schedule keeps a minor issue from shutting down your heat during business hours.

Planned maintenance catches much of that wear early. A routine visit lets our team clean, inspect, and test the system before the heating season puts it under strain. Ask our office about a maintenance schedule that fits your building and business hours.
