Claim This BusinessUnder The Sun Heating And Cooling has operated as a Denver-based heating contractor since 2021, delivering furnace and air conditioning services across the Front Range. The business holds Colorado contractor licensing and maintains a 4.5-star average across 11 verified customer reviews. Owner-operator Joe serves residential clients throughout Denver proper, including neighborhoods in central and southeast Denver, responding to emergency calls when furnaces fail during the region's notorious winter cold snaps and summer heat waves.
What distinguishes this contractor is Joe's commitment to working with existing equipment rather than automatically recommending full system replacement. Multiple reviewers describe how he inspected functioning furnaces before proposing AC installation, finding solutions that avoided cutting ceilings or floors. This cost-conscious approach saved one homeowner thousands of dollars compared to competitor bids exceeding $10,000. The business offers high-efficiency furnace and thermostat installations, and Joe provides flexible scheduling with payment accepted only after all work passes inspection.
Customer experiences highlight rapid response during system failures. When one reviewer's furnace stopped working, Joe arrived the same day while competing companies quoted two-week wait times. Another reviewer noted Joe returned next morning to address small follow-up items discovered during installation. While one customer reported unresolved AC issues and communication challenges, the majority of reviewers praise Joe's transparency, thorough explanations of repair versus replacement options, and willingness to walk through each step of the process.
9 of 11 reviewers award 4 or 5 stars, with Joe praised for same-day emergency response, transparency about repair options, and flexible payment timing. The single 1-star review cites an AC repair that did not resolve the problem and missed follow-up communication.
