About Lakeside Heating & Air Conditioning
Lakeside Heating & Air Conditioning has served Arvada homeowners since its founding as a family-owned contractor, earning a 4.9-star rating across 328 client reviews. The business handles heating and cooling installations, replacements, and repairs for residential and light commercial properties throughout Arvada and neighboring communities including Westminster, Golden, and Lakewood. Tony and his team guide each customer through equipment options, installation approaches, and available utility rebates, treating every project as a custom solution rather than a one-size-fits-all pitch.
Each project begins with Tony presenting multiple bids that account for the specific needs of the home, whether a 40-year-old furnace requires replacement or a full system upgrade includes humidification. Installers Mick, Nicholas, Chael, and Derrick remove old equipment cleanly, install new systems with careful attention to flooring and workspace protection, and walk homeowners through thermostat operation before leaving. The office staff including Holly, Marissa, and Bill manage permitting, coordinate inspections, and handle questions promptly, keeping the experience smooth from quote to final inspection.
Reviewers consistently highlight specific experiences that differentiate Lakeside from larger competitors. R Tisdall describes recommending the team to multiple neighbors after Mick and Nicholas answered questions throughout a meticulous installation. Joshua Bertrand credits Tony for a thorough quote with options, and credits Marissa and Holly for making the permit inspection process seamless after the installation crew delivered what he calls an amazing product. Nick Dadamio notes the crew arrived within a week of the initial estimate and completed installation in a single day, explaining the new thermostat thoroughly.
What Customers Say
