What Is Preventive Maintenance for HVAC Systems and Why Is It Important?

Preventive HVAC maintenance means scheduled tune-ups and safety inspections that keep your AC, heat pump, and furnace running reliably and help prevent breakdowns. In Las Vegas and Henderson, Sierra provides annual 15-point cooling and heating tune-ups and performance checks. Our S.A.M. plan is $16/month and includes up to four visits a year, priority service, and a 65-point plumbing inspection. Tune-ups come with a No-Breakdown Guarantee for 6 months. Members get 15% off repairs, a 2-year parts and labor repair warranty, and value-added coil cleaning on qualifying systems.
