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.

Commercial Cooling Equipment We Install, Repair, and Maintain

Commercial cooling systems carry heavier loads than residential units, and every building handles that load differently. Our NATE-certified technicians start by identifying the equipment your space relies on, how it is configured, and how hard it works through a typical Elgin summer.

Many businesses run rooftop packaged units, while others use split systems with indoor air handlers and outdoor condensers. Some buildings combine several units serving separate areas. Whatever the setup, our team assesses the full system before recommending commercial AC repair in Elgin, IL, or a replacement.

Cooling performance also depends on the parts around the equipment. Leaky or undersized ducts waste conditioned air, so we may recommend ductwork repair and replacement in Elgin, IL when the duct system is the real problem. Buildings with uneven temperatures from one area to the next can also benefit from HVAC zoning in Elgin, IL.

Fast Commercial AC Repair and Scheduled Maintenance Plans

When a commercial AC system fails, it affects employees, customers, and sometimes inventory all at once. Our technicians diagnose the cause, explain what they found in plain terms, and give you the price before starting any commercial AC repair.

Common trouble signs include warm air from the vents, short cycling, unusual noises, water pooling near the unit, and energy bills that climb without explanation. Calling at the first sign of trouble gives our team the chance to fix a small problem before it turns into a larger one.

Commercial equipment often runs longer hours than a home system, so parts like belts, fan motors, and capacitors wear out faster. Replacing a worn part on time keeps a minor issue from becoming a full system failure during business hours.

Northern Illinois summers bring long stretches of heat and humidity that push commercial systems hard. Problems that stay hidden in spring often surface during the hottest weeks, when your building needs cooling the most. Our EPA-certified technicians handle refrigerant work correctly and safely during every visit.

Scheduled maintenance helps prevent many of those breakdowns. A routine visit lets our team clean, inspect, and test the system so wear gets caught before it shuts your building down. Ask our office about setting up a maintenance schedule that fits your building and business hours.
