Idaho weather doesn't compromise, and neither do we. From a furnace that quits on the coldest night to an AC that can't keep up in July, J&D repairs, replaces, and maintains it all — fast, clean, and with a straight answer about what your system actually needs.
Heating
Warm all winter, no cold nights waiting
When the temperature drops, a reliable heating system isn't a luxury. We service and install every kind so your home stays comfortable no matter how the Idaho winter behaves.
Furnace repair & replacement

Heat pumps
Efficient, all-electric heating and cooling in one system — a smart upgrade that lowers bills and works year-round.
Ductless mini-splits
Perfect for additions, shops, and older homes without ductwork — room-by-room comfort with no major remodel.
Cooling
Cool that keeps up with an Idaho summer
Treasure Valley afternoons hit triple digits. A properly sized, well-maintained system holds temperature all day without running your bill through the roof — and we make sure yours does exactly that.

Financing on new installs
A full furnace or AC replacement runs $8–12k. Flexible monthly payments keep the comfort coming without the up-front sticker shock.
Demo noteThis financing block is what converts the $8–12k system shopper who'd otherwise stall or price-shop. Confirm your financing partner and terms and we'll swap in real "as low as $X/month" numbers.
Indoor air quality
Cleaner, healthier air in every room
Comfort isn't just temperature. We help Treasure Valley families breathe easier with whole-home solutions that quietly work around the clock.
Air purification
Whole-home air cleaners that capture dust, allergens, and smoke — a real difference during wildfire season.
Humidifiers
Balanced humidity that protects wood floors and skin from the dry Idaho winter, tied right into your system.
Duct cleaning & zoning
