Tim Stivers Heating / Air Conditioning

Tim Stivers Inc. has served Los Angeles and Pasadena homeowners since 2000, building 24 years of trusted HVAC expertise under founder Tim Stivers, who began his career at LA Trade Technical College studying Heating, Air Conditioning & Refrigeration. The independently owned company holds a state contractor license and maintains a 4.6-star rating across 22 verified customer reviews, offering both residential and light commercial heating and cooling services from Monday through Friday, 7 AM to 5 PM, plus after-hours emergency response. Property owners and managers throughout the greater Los Angeles basin rely on Tim Stivers for installation, repair, and maintenance of systems from Rheem, Lennox, Trane, Carrier, Goodman, Amana, and American Standard.

What distinguishes Tim Stivers from typical HVAC shops is the combination of honest diagnosis-first practices and a 100% satisfaction guarantee backed by fully insured workmanship. The company specializes in uncovering underlying problems that previous contractors misdiagnosed, frequently delivering targeted repairs instead of full system replacements. Their air purification offerings include UV germicidal lights, humidifiers, dehumidifiers, and duct sealing services alongside traditional heating and cooling work, giving Los Angeles homeowners a single resource for indoor air quality improvements alongside standard equipment service.

Customer reviews repeatedly emphasize the accuracy of initial diagnoses. Technician Tim saved one homeowner nearly $5,000 by identifying a $150 failed component instead of recommending furnace replacement, a scenario repeated across multiple testimonials where competitors pushed unnecessary upgrades. During a recent heatwave, Julie Berghofer secured same-day scheduling despite a fully booked schedule, illustrating the companys willingness to accommodate urgent calls. Todd Allen, with 27 years in commercial construction management, credits the team for two new HVAC installations and ongoing maintenance that exceeds industry standards.
