Years fixing furnaces in Porter County

24/7

No-heat line, answered by a person

Most calls are one of these six. If yours isn't, call anyway. We'll tell you straight if it's a job for someone else.

  • 01

    Furnace repair

    Same day

    No heat, short cycling, a smell you don't like. The common parts ride on the truck, so most repairs finish on the first visit.

  • 02

    AC repair

    Warm air from the vents or ice on the lines. Diagnosed in one visit and priced before we start.

  • 03

    New systems

    When repair stops making sense, we'll show you the math. Honest quotes on the major brands, installed by our own crew, never subcontracted.

  • 04

    Tune-ups

    Before the first cold snap and the first heat wave. Twenty-one points checked, filter changed, a written report with photos.

  • 05

    Indoor air quality

    Humidifiers, whole-home filters and duct cleaning for the house that's always a little dusty or a little dry.

  • 06

    Water heaters

    Tank or tankless. Same-day swap for most standard tanks, so nobody takes a cold shower twice.

A typical Tuesday in January: a quiet furnace in Chesterton, a tech from our shop in Valparaiso, about ninety minutes start to finish.

A person answers

Sarah picks up on the second ring. She asks what the furnace is doing, how cold the house is, and whether anyone home is very young or very old.

A technician working under a sink

Since 1999

Dale Wozniak was a union pipefitter who got tired of watching people overpay. He started Cranefield with one van and a pager in 1999. His daughter Renee runs it now, and he still drops by most Fridays with donuts.

We're fourteen techs, two dispatchers and one very particular office dog. Every tech is ours: trained here, paid hourly, never on commission. That last part matters more than it sounds.

“Nobody on this team gets paid more for selling you a furnace. That's on purpose.”
Renee Wozniak, owner
  • Price agreed before work starts
  • Techs paid hourly, never commission
  • Two-year guarantee on repairs
  • Shoe covers, every time

Most breakdowns we see in January started as something small in October. The club is how you catch them early.

  1. 1We call within one business day to set a time.
  2. 2A tech walks the house and checks the ductwork. About an hour.
  3. 3You get a written quote with two or three options, good for 30 days.

Called at 7:40, he was in my basement by 8:30. Honest about what it needed, and what it didn't.

Another company quoted us a whole new system. Cranefield replaced a $90 part. That's how you get a customer for life.
TLTom & Linda K.Chesterton · 1 month ago
Shoe covers on without being asked, and they cleaned up better than we keep the place.
AWAndre W.Portage · 3 weeks ago
AC died during the July heat wave. They dropped two fans at our door within the hour while they waited on the part.
PSPriya S.Kouts · 2 months ago
No commission, no pressure. He actually talked us out of the upgrade.
JBJim B.Wheeler · 1 week ago
Renee called the next day to make sure the heat was still holding. Who does that anymore?
CMCarol M.Porter · 5 days ago
Fair price, on time, and the dispatcher remembered our dog's name from last year.
STSam T.Valparaiso · 3 months ago
Tankless water heater swapped the same day. The install looks like it came out of a catalog.

Still not sure? Call us. A person answers.
