Ariston Heating and Cooling - HVAC Contractors

Ariston Heating and Cooling has earned a 4.9-star rating across 93 reviews in Pacheco, California, establishing itself as a trusted name in residential climate control throughout the Lamorinda valley and beyond. The family-owned contractor proudly serves Orinda, Lafayette, Moraga, Walnut Creek, Concord, Danville, and surrounding communities, bringing licensed expertise to homeowners seeking reliable heating and cooling solutions. With direct access to ownership and competitive pricing, Ariston differentiates itself by eliminating the traditional sales-middleman model and connecting customers with knowledgeable technicians from the first call.

What sets Ariston apart is their specialization in both traditional HVAC systems and niche wine cellar climate control, a rare offering in the residential market. As an American Standard dealer, they provide installations ranging from conventional furnaces and central AC to modern mini-split ductless systems and heat pumps. The company backs their work with available financing options and maintains a service portfolio that includes air filtration optimization alongside wine cooling systems, demonstrating breadth beyond standard residential service.

Customer stories reveal a team that responds when it matters most. When Sameer Khera's furnace and AC failed simultaneously right after Christmas, Alekos and crew completed a full American Standard system replacement within a single day. For J. Erb's community property, Ariston saved thousands by researching and confirming the existing electrical infrastructure could support a new mini-split without costly upgrades other contractors demanded. Technicians Aghiles and Alejandro are specifically praised for clean, efficient vent relocation work, while Alekos is recognized for taking time to explain heat pump options and energy optimization to homeowners.
