Claim This BusinessDalco Air Conditioning and Heating Company has kept the lights on in Dallas homes since 1963, operating as a four-generation family business from 7310 Military Parkway. Texas license TACLA001755C and plumbing license M18369 anchor their credentials alongside a 4.4-star rating drawn from 40 client reviews. They serve residential, commercial, and industrial customers throughout North Central Texas, including Dallas proper and surrounding communities. This contractor maintains 24-hour availability across every day of the week, a critical detail for Texas homeowners facing sudden AC failures during summer spikes or winter freezes.
What distinguishes Dalco from neighboring contractors is their Lennox partnership and NATE-certified technician team, allowing them to install and service premium variable-speed systems including the iComfort S30 and WiFi thermostats. Their indoor air quality specialty incorporates REME HALO germicidal lights, disinfecting fogging, and thorough duct cleaning, a capability few Dallas contractors advertise. Home Comfort Plans provide structured maintenance options, while their smart thermostat programming lets homeowners control heating and cooling remotely via smartphone. Generator installation rounds out their year-round service offerings, ensuring climate control continues through power outages.
Customer stories from recent reviews reveal why Dalco earns repeated calls. When Katie Weyandt's heater failed on a cold night, Dalco dispatched a technician within 30 minutes, she noted technician Jonathan arrived with full parts knowledge and provided an upfront estimate before work began. Shirley Rumsey needed emergency service late in the day and described how coordinator Kate ensured a technician reached her within the hour, with the team explaining each step while keeping pricing reasonable. These same-day emergency responses, combined with upfront cost disclosure, appear consistently in the higher-rated reviews.
Three of six detailed reviews cite same-day or same-hour emergency response, with positive reviews specifically naming technicians Jonathan and Nathan. Negative reviews focus on pricing disputes and delayed follow-up rather than technical competency.
