Parents furnace went out around Christmas time. Bob came very quick and replaced the faulty inducer. Upon inspection of the furnace he noticed the heat exchanger was in bad shape on this 20+ year old unit. Bob & his team came back and replaced the whole furnace. Job was done very neatly, affordably & professionally. Would highly recommend B&Z heating to anybody in the south suburbs. 5 stars !

Let me start by saying that I have always been very cautious because almost every company tries to rip people off. Well, let me tell you, B&Z provides honest, fair, and quality services. They are a family-owned and operated company. My furnace was overheating due to the wrong air filter. They came, inspected the unit, and scheduled me for a follow-up cleaning. I will be a regular customer and will be getting my yearly cleaning with B&Z from now on!

B & Z is the best. Bob and his crew responded very quickly and helped me make the right decision on a new furnace and AC unit. Unlike many HVAC providers I’ve worked with, Bob carries and can provide any of the major brands, so he does not push one brand and upsell for more than you need. He did a thorough analysis and test to determine the appropriate size systems and gave me options on good, better, best and associated pros and cons. Most importantly Bob is honest and trustworthy. Quick response, comprehensive evaluation and recommendations, competitive and fair pricing and high quality installation. Highly recommend B & Z!

When your boiler is short-cycling, leaking around the base, or leaving rooms cold no matter how high you turn the thermostat, replacing it is usually smarter money than one more repair on a cracked heat exchanger or a rusted-out cast-iron block. B&Z installs high-efficiency gas boilers across Orland Park and the southwest suburbs, sized to your home's real heat loss and matched to whatever you heat with, whether that's old cast-iron radiators, baseboard, or radiant floor loops. You get a free estimate, honest no-upsell pricing, and NATE-certified techs who set the near-boiler piping up right the first time.
An aging boiler leaks more, heats less, and costs more to run every winter. Here's when replacing beats repairing.
Most boilers last around 15 to 20 years, so an older unit is often worth replacing before it fails mid-winter.
You're paying for repairs most seasons, and those bills are climbing toward the cost of a new boiler.
Your heating costs keep going up while comfort drops, a sign the old boiler has lost efficiency.
You keep finding leaks, rust, or corrosion on the boiler or its pipes, which usually can't be patched for long.
Rooms take a long time to warm up or never heat evenly, even after repairs and bleeding the radiators.
The boiler is loud, or it runs almost non-stop to keep the house warm, both signs it's near the end.
We size the new boiler to your home and your radiators, not to a sales target.
We look at your home's heat needs, radiators or baseboards, and piping so the new boiler is matched to the way your home is heated.
You get a clear recommendation for a boiler that fits your home and budget, with no pressure to over-buy.
We give one upfront price with no hidden fees, and financing is available on new systems to spread the cost.
Our technicians install the new boiler, bring it up to proper pressure, test it, and remove your old unit and any debris.
A few things move the price more than anything else. The biggest is the boiler itself, meaning how many BTUs your home's heat loss actually calls for and whether you choose a standard cast-iron unit or a high-efficiency condensing boiler that needs its own PVC venting and a condensate drain line. Fuel type factors in too, since a natural gas, propane, or oil boiler each connects a little differently. What you're heating matters just as much. Tying a new unit into existing cast-iron radiators, fin-tube baseboard, or a radiant floor system changes the near-boiler piping, circulator pumps, expansion tank, and zone valves we have to install. The practical details add up from there, including how many heating zones you run, whether your gas line and venting are sized for the new equipment, how accessible the basement or mechanical room is, hauling out the old heavy boiler, and the permit and inspection your town in Cook or Will County requires.
