"Furnace died on the coldest night of the year. Called Bob Boldt first thing in the morning and they had a tech out by 10 AM. Fixed it same day, explained everything, charged exactly what was quoted."

From a first-freeze furnace emergency to a full system upgrade, we handle every heating job with honest pricing, NATE-certified technicians, and zero pressure. Family-owned in the South Metro since 1988.
Minnesota winters don't forgive a broken furnace. Whether you need a quick repair, a seasonal tune-up, or a full system replacement, Bob Boldt HVAC has been the trusted heating partner for South Metro families since 1988.
We fix what can be fixed, replace what needs replacing, and never upsell what you don't need. Every job starts with a clear, written quote, no surprise bills, no high-pressure tactics. And if you've already been quoted by someone else, we'll give you a FREE second opinion.
System running but not warming, or back bedrooms that never get comfortable.
Furnace turns on and off every few minutes instead of running proper heating cycles.
Gas or electric bills climbing with no change in usage = system losing efficiency.
Banging, rattling, whistling, or grinding, all signs something's failing inside.
Most furnaces and boilers peak at 15–20 years. Past that, efficiency drops fast.
Stop using your furnace immediately and call us, this is a safety issue, not a wait-and-see.
We've built our reputation one honest quote at a time. Here's what sets us apart from the big-box heating companies.
Firm, written quote before we start, never a bigger bill at the end.
Three decades serving the South Metro. Same family. Same standards.
The industry's gold standard. Every tech trained, tested, and current.
Got a quote elsewhere? We'll review it at no charge, no obligation.
If your new system is a dud, we replace it, not just patch it up.
If you're not thrilled with the work, we make it right. Full stop.
Same honest process whether you need a quick repair or a full system replacement.
We visit your home, diagnose the issue, and listen to what matters to you, no charge, no pressure.

NATE-certified techs do the job right. Floors protected, old equipment hauled, system tested end-to-end.
We check in after every job, and back everything with manufacturer warranty plus our No Lemon Guarantee.
Heating work ranges widely, a simple repair might run $150–$500, a full furnace install $4,500–$9,500. What's consistent: you get a firm, written quote before any work starts, and we stick to it.
