When your boiler stops firing on a January morning in Skokie, you don't have time to shop around for days. You need a straight answer, a fair price, and heat back in the house. Ultimate HVAC Inc. handles boiler installation and boiler repair across Skokie, IL with same-day service and 24/7 availability. Whether you've got a leaking cast-iron unit in an older Skokie bungalow or a modern condensing boiler that's throwing error codes, we diagnose the real problem and fix it — no upsells, no runaround.
What boiler installation and repair involves
Boilers are different animals than forced-air furnaces. Instead of pushing heated air through ductwork, they heat water (or produce steam) and circulate it through radiators, baseboards, or radiant floor loops. That means the work involves plumbing, gas lines, venting, electrical controls, and pressure systems all at once.
A boiler repair visit typically starts with checking the ignition sequence, pressure gauge, expansion tank, circulator pump, zone valves, and the flue. Common issues we see in Skokie homes are failed thermocouples, waterlogged expansion tanks, seized circulators, low-water cutoff faults, and cracked heat exchangers on units that have been pushed past their service life.
A boiler installation is a bigger job. We size the unit to your actual heat load — not the size of whatever was there before, because oversized boilers short-cycle and waste fuel. Then we handle the gas connection, near-boiler piping, venting (B-vent or direct-vent PVC depending on the unit), condensate drainage on high-efficiency models, and full commissioning with combustion analysis before we leave. Every job gets pressure-tested and cycle-tested before we call it done.

Our boiler service process
- Phone call. Tell us what the boiler is doing (or not doing). We'll give you an honest read on whether it sounds like a same-day fix or a replacement conversation.
- On-site diagnosis. A tech comes out, inspects the unit, checks pressure, gas, ignition, and controls, and identifies the actual failure point.
- Written estimate. You get the repair cost or replacement quote in writing before any work starts. No verbal maybes.
- Repair or install. For repairs, we carry common parts on the truck. For installations, we schedule the swap, protect your floors, and pull the old unit out.
- Commissioning and testing. Combustion analysis on new installs, pressure test on the water side, and a full cycle through every zone in the house.
- Walk-through. We show you the pressure gauge, the shutoff, the thermostat behavior, and what to watch for.
- Follow-up. A check-in after the first cold week to make sure the system is running the way it should.
What boiler installation and repair typically costs
Boiler pricing swings widely because the work does. A minor repair — replacing a thermocouple, bleeding air out of a zone, swapping a pressure relief valve — is a small ticket. A failed circulator pump, zone valve, or expansion tank is a mid-range repair. A cracked heat exchanger or a failed control board usually pushes the conversation toward replacement, because you're already halfway to a new boiler in parts and labor.
For full boiler installations, cost is driven by the BTU size you need, efficiency rating (standard 80%+ vs. high-efficiency 90%+ condensing units), whether the near-boiler piping and venting need to be reworked, and how many zones the system runs. Gas line upgrades and chimney liners can add to the total when required by code.

FAQ
How long does a boiler installation take in a Skokie home?
Most straightforward boiler swaps take one to two days. If we're re-piping the near-boiler manifold, adding a chimney liner, or reworking venting for a high-efficiency unit, it can stretch to three days.
My boiler is 25 years old but still runs. Should I replace it?
Not necessarily. If it's holding pressure, firing cleanly, and heating the house evenly, you can often get a few more seasons out of it with proper maintenance. We'll tell you honestly where yours stands.
Do you work on steam boilers, or just hot water?
Both. Skokie has plenty of older homes with one-pipe and two-pipe steam systems, and we service them along with modern hot-water and high-efficiency condensing boilers.
What's the difference between a standard and high-efficiency boiler?
Standard boilers run around 80–84% AFUE and vent through a chimney. High-efficiency condensing boilers hit 90%+ AFUE, vent through PVC out a sidewall, and produce condensate that drains to a floor drain. Higher upfront cost, lower gas bills.
Do you offer emergency boiler repair at night or on weekends?
Yes. We're available 24/7, including weekends and holidays, for no-heat calls in Skokie and surrounding areas.
What's your $140 seasonal offer?
It's our seasonal tune-up — a full inspection, cleaning, and combustion check to get your boiler ready before heating season hits.
