Heating and cooling emergencies in Boise

Heating contractors and plumbers for breakdowns.

50 pros in Boise

When a furnace quits or an air conditioner fails in Boise, the repair can turn into a permit question. The city requires mechanical permits when vents and ducts are added, replaced or relocated, and its Homeowner's Guide says this includes replacing furnaces and air conditioning units. So a simple repair is one thing, but a replacement is work the city expects to be permitted. Idaho also lets a homeowner buy a permit only for electrical, plumbing or HVAC work on their own primary or secondary residence and related outbuildings, and those permits are not valid for commercial buildings. Before you hire, ask whether the job is a repair or a replacement, and who will pull the permit. Ask to see the contractor's Idaho HVAC licence, and get the scope of work in writing. If the power is out and you are thinking about a generator to keep heat or cooling running, Idaho Power says a portable unit should never be plugged into house wiring unless a qualified professional has installed proper transfer equipment.

  3. Put it in a written contract: the work, price, deposit, start and finish dates, warranty, permits and clean-up. Paying cash to skip it leaves you no recourse.

Questions about hiring in Boise

Do I need a permit to replace a furnace or air conditioner in Boise?

Yes, in most cases. Boise requires mechanical permits when vents and ducts are added, replaced or relocated, and the city's Homeowner's Guide says this includes replacing furnaces and air conditioning units. Ask your contractor whether a permit applies and who will obtain it before work starts. City of Boise (source, opens in a new tab)

Can I pull the permit myself for HVAC work on my home?

Idaho lets a homeowner buy a permit for electrical, plumbing or HVAC work on their primary and secondary residence and related outbuildings. It is not valid for commercial buildings. If you hire a contractor, confirm in writing whether they or you are responsible for the permit. Idaho Division of Occupational and Professional Licenses (source, opens in a new tab)

What should an HVAC repair quote include?

Ask for the equipment involved, the work to be done, parts and labour listed separately, any permit, the timeline, and warranty terms. Get it in writing before work begins. If you collect several quotes, compare them line by line rather than by the total alone, and ask about anything that differs.

Can I run a generator to power my furnace during an outage?

Idaho Power says a portable generator should never be connected to house wiring or plugged into an outlet unless a qualified professional has installed proper transfer equipment. Have a licensed professional set up the connection before you rely on a generator for heating. Idaho Power (source, opens in a new tab)
