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.

Is It Time for a New Furnace? Warning Signs to Watch For

Elgin winters put steady demand on a furnace from late fall into spring, and an aging system usually shows the strain. These signs often mean furnace installation in Elgin, IL, makes more sense than another repair.

Frequent repair calls
Rising winter heating bills
Uneven heat between rooms
Yellow or flickering burner flame
Loud banging or rattling

One sign on its own does not always call for a new system. Our technicians inspect your furnace first, and if a fix will hold, we will recommend furnace repair in Elgin, IL instead of a full replacement.

What's the Average Lifespan of a Home Furnace?

A furnace’s lifespan depends on how well it was installed, how consistently it was maintained, and how hard it has had to work. Long Illinois heating seasons add hours of runtime every year, which wears down blowers, igniters, and heat exchangers.

Age matters most when it lines up with other warning signs. An older furnace that needs frequent repairs and costs more to run each winter is usually a better candidate for furnace installation in Elgin, IL, than for another round of patchwork.

Routine care helps any system last longer. Pairing a new furnace with yearly furnace maintenance in Elgin, IL protects your investment and keeps efficiency where it should be.

Choosing the Right Furnace for Your Home

The right furnace depends on your home’s size, layout, and insulation, plus how you want to balance upfront cost against monthly energy use. Sizing comes first. A furnace that is too large cycles on and off constantly, while one that is too small runs nonstop on the coldest Elgin nights.

Furnaces also differ in how they deliver heat. Single-stage units run at full output every time they turn on, while two-stage and modulating models adjust to the weather outside for steadier comfort and quieter operation. Efficiency ratings, listed as AFUE, show how much of the fuel you pay for becomes usable heat.

Our technicians walk you through the options that fit your home and budget, with no pressure to buy more furnace than you need. If you are weighing alternatives, we can also compare a new furnace with heat pump installation in Elgin, IL.
