Claim This BusinessAbout Guardian Heating & Air Conditioning
Guardian Heating & Air Conditioning has earned a 4.8-star average across 21 reviews since establishing in the Centennial area. The company deploys NATE-certified technicians who handle air conditioning and furnace work for homeowners across Centennial, Aurora, and neighboring communities. Emergency service is available 24 hours a day, 365 days a year, with no mention of holiday surcharges or after-hours premiums on the website. The company also advertises HVAC financing to spread costs over time for customers facing unexpected equipment replacement.
The NATE certification held by Guardian's technicians signals a voluntary industry credential requiring passage of rigorous hands-on exams, distinguishing this crew from contractors holding only basic state licenses. Beyond standard AC and heating work, the team addresses indoor air quality using a product called PremierOne, which the website specifically ties to concerns about airborne viruses, a mention grounded in the same page where the company describes following CDC guidelines during service calls. A free downloadable Heating and Cooling Efficiency Guide offers homeowners a planning tool without requiring a phone call first, suggesting the company invests in customer education before any sale begins.
Kurt appears by name in six of eight reviews, with Magda Jabbar describing eight years of repeat calls for furnace and AC issues where Kurt "responds as soon as he can" and offers honest repair advice without pushing unnecessary replacement. Joni Jenson specifically names both Kurt and Eric as the crew members who handled multiple home jobs, praising their reliability and hard work. Wayne Kinder's review documents a church furnace installation where Kurt and an associate removed the old unit and commissioned the new one in just over three hours while preschool activities continued uninterrupted. Shannon Greer explicitly contrasts her experience with other contractors, stating she never felt upsold or cheated across years of both emergency calls and routine service visits.
What Customers Say
All eight published reviews award 5 stars, with Kurt named in six of them as the primary point of contact. Wayne Kinder's church project and Magda Jabbar's eight-year customer relationship each provide dates or project scopes that suggest sustained rather than transactional service. No negative reviews were present in the dataset.
