Tap your situation - we'll connect you to an HVAC technician on our line.
Smell gas? Turn off your furnace and call (208) 231-1635 immediately.
Tell us what your furnace is doing - no heat, won't start, making noises. We send an HVAC technician trained across all major brands.
On-site inspection, combustion and CO safety test, and a real diagnosis - not a sales pitch for a new unit.
Repair completed, system tested under load, and a final safety check before we leave. You get heat back - and confidence it's safe.
Furnace repair is the one service where cutting corners can cost lives. A skipped combustion check misses a cracked heat exchanger, which vents CO into your home. Here's how Diamond is different.
Fully-stocked trucks and experienced HVAC technicians mean most furnace repairs are one-visit, not a return trip in a week.
A cracked heat exchanger can vent carbon monoxide into your home without warning. Every furnace we service gets a full combustion safety check.
If your furnace is at end of life, we'll say so - with numbers. If it's a $250 fix on a 10-year-old unit, we'll say that too. Your call, not a sales pitch.
We answer live, 24/7 - and dispatch same-day in most cases. Walking you through what's wrong starts on the phone.
Diamond isn't a private-equity rollup. It's a 26-year Treasure Valley business - built by Rick and Sue Ellen, around a single idea: do home services the way homeowners deserve.
Rick opened Diamond's doors in March 1999, focused on new construction. He earned a reputation across the Treasure Valley for solving the hot-bonus-room problem nobody else could fix - and for treating customers fairly when others didn't.
In 2009, Rick's wife and business partner Sue Ellen joined full-time. Together they made the call to pivot from new construction to residential service - because they saw an industry that, too often, didn't take care of its customers. They wanted Diamond to stand for the opposite.
That standard is what built the company you see today - the awards, the reviews, the 1,800+ permitted projects on record. None of it happened by accident.
We were impressed with their up-front and clear pricing. John was on time, and explained everything necessary to do with no pressure to do it.
Diamond Heating and Cooling was very knowledgeable and professional from start to finish. Highly recommended.

Diamond is based in Garden City and serves homeowners across the Treasure Valley & surrounding areas.
