The questions we hear most.

It depends on the system's age, the cost of the repair versus a replacement, and how long you'll stay in the home. Our rule is the “our own home” test — we'll tell you which option makes sense, and we'll never push a replacement when a fair repair will do.

Yes — and it's free. Bring us any repair or replacement quote and we'll review it apples-to-apples, with no pressure and no obligation. If their price is fair, we'll tell you so.

Most equipment changeouts and plumbing alterations in Lake and Cook County do — water heaters, AC and furnace changeouts, gas lines, and sewer or water-line work. Requirements vary by town, and we pull the permit and handle the inspection for you.

Yes. Cold-climate heat pumps keep producing heat well below 0°F, and in our climate we typically pair one with a backup furnace (a dual-fuel setup) so you're never caught short on the coldest nights.

Yes. We provide free, no-obligation estimates on installations and replacements. For repairs, we use upfront flat-rate pricing — you approve the exact price before any work begins, so there are never surprises.

Same-day service is often available, and we offer 24/7 emergency dispatch for urgent issues like a no-heat night or a burst pipe. Maintenance-plan members get front-of-the-line priority scheduling.

Yes — Legendary Service is fully licensed, bonded, and insured, and every technician is background-checked. We've been family-owned since 2008 with a 5.0-star Google rating across hundreds of reviews.

We use upfront, flat-rate pricing. After diagnosing the issue, your technician presents your options — with the pros, cons, and exact cost of each — and you approve the price before work starts. No hourly meters, no hidden fees.

It varies widely — the equipment is only part of the job. Your home's size, ductwork, efficiency level, and what's behind the walls all move the number, so any exact price quoted sight-unseen is a guess. We give you one upfront flat rate after seeing your home.

Yes. We partner with trusted lenders to offer flexible monthly payment options, so an unexpected repair or a new high-efficiency system doesn't have to wait for the budget. Options are subject to credit approval — ask us and we'll walk you through what fits.

We offer senior and military appreciation pricing, and maintenance-plan members receive members-only repair pricing year-round. Ask your technician what applies to your visit.

In the Chicago area, most furnaces last 15–20 years and air conditioners 12–18 years, depending on use and maintenance. Once a system passes that range or needs frequent repairs, we'll walk you through repair-vs-replace as if it were our own home.

R-454B is the lower-global-warming refrigerant that replaced R-410A in new air conditioners and heat pumps as part of the 2025 transition. We install current-standard equipment so your investment stays compliant and serviceable — and because it's a mildly flammable (A2L) refrigerant, a properly trained, permitted install matters more than ever.

We recommend two visits a year — a spring tune-up for your AC and a fall tune-up for your heating system. Seasonal maintenance keeps efficiency high, catches small issues early, and protects your manufacturer warranty.

Yes — from a dripping faucet to a burst water line at 2am. We cover water heaters and tankless systems, drain cleaning, sewer lines (including sewer lining and point repair), sump pumps, water softeners, repiping, and more.

Absolutely. Lake County water is notoriously hard, which damages fixtures and appliances over time. We install and service whole-home water softeners and filtration systems sized to your household.

Yes. For older North Shore homes especially, a camera inspection pinpoints root intrusion, cracks, and bellies before they become emergencies — and lets us recommend targeted sewer lining or point repair instead of a full dig.

Every job is backed by a 100% satisfaction guarantee. If something isn't right, we make it right — because our goal isn't one transaction, it's earning the next ten to twenty years of your trust.

No. We recommend exactly what we'd install in our own home — and we'll tell you when a repair isn't worth it on failing equipment. Half our job is teaching you enough to make the right choice with confidence.
