If your home heater is not working, start with a few safe checks to rule out simple issues before you call for service. The most common culprits are thermostat settings, a tripped power switch or breaker, and a clogged air filter that forces the heater to shut down. If heat doesn’t return, the problem is likely in the ignition system, blower, or control board and needs a technician; no-heat during freezing weather is urgent. Technicians in the Treasure Valley often find an accidentally switched furnace service switch or a dirty filter behind many no-heat calls. 24/7 emergency help and free second opinions on major repairs are available after your basic checks.
Try these quick checks first:
- Set thermostat to Heat and 3–5° above room temp; replace batteries if used.
- Replace a dirty filter and reopen all supply/return vents.
- Verify the furnace switch is On and reset any tripped breaker once.
- Note any error code or flashing light and power-cycle the unit once.
If you smell gas or see scorch marks, leave the area and contact your utility before any HVAC service.

"Excellent service!" — Corey T.
There isn’t a single set price for furnace replacement. Diamond Heating and Cooling provides free equipment estimates and offers financing options. Final cost depends on home size, fuel type, efficiency rating, existing ductwork, and any add-ons. A technician confirms pricing on site. Installations include a performance guarantee; if the new furnace doesn’t reach your set temperature range, we replace it at no charge. We also offer a two-year money-back satisfaction guarantee on new equipment. We’re available 24/7 for emergencies in Boise, Meridian, and Nampa.

A new furnace for a 2,000 sq ft home does not have a one-size price. We confirm final costs after an in-home assessment. Key factors include equipment size and efficiency, fuel type, duct or vent changes, thermostat or indoor air quality add-ons, and any Boise area code upgrades. Diamond offers free equipment estimates, 24/7 emergency service, and financing options, including no-interest and deferred plans through Service Finance and Synchrony. We serve Boise, Meridian, Nampa, and the Treasure Valley.
