Claim This BusinessAvis Plumbing and Air has served Fullerton, Anaheim, and the broader Orange County community for decades as a fully licensed contractor offering both HVAC and plumbing services under one roof. With a 4.7-star average across 489 client reviews, the company has earned a reputation for reliable diagnostics and straightforward pricing in a market where homeowners often report confusion over repair costs. Their Monday-through-Friday schedule runs 7 AM to 5 PM, with Saturday hours from 8 AM, making them accessible for routine maintenance and urgent calls alike.
What distinguishes Avis is their Maintenance Club, a prepaid annual program that covers priority scheduling and multi-point inspections across both HVAC and plumbing systems. The company installs and services ductless mini-split systems alongside conventional central AC and furnace equipment, handling heat pump technology for homeowners who want a single unit managing both heating and cooling. Financing options are available for full-system replacements, which reviewers note helped make a major investment feel manageable when their aging equipment finally failed.
Customer reviews repeatedly name technician John, sometimes called JR, for going beyond surface-level troubleshooting. One homeowner reported that after an AC condenser failure, John opened the unit, showed actual component ratings compared to factory specs, and completed the repair for a fraction of a competitor's estimate. Another reviewer described John's methodical furnace inspection, where he walked the homeowner through each diagnostic step while wearing protective booties and explained additional services without pressure. A third reviewer highlighted the company's transparent written quotes as the reason they chose Avis over rivals who quoted higher prices without itemized breakdowns.
Four separate five-star reviews specifically mention technician John or JR, praising his thorough diagnostics, patient explanations, and fair pricing on both AC and furnace work. Across these accounts, customers consistently highlight upfront cost disclosure as a deciding factor in choosing Avis over competitors who pushed costly repairs without showing their work first.
