All Service Heating, Air & Plumbing

All Service Heating, Air & Plumbing has kept North Texas families comfortable since 1986, when Wayne Polen founded this family-owned company in McKinney. With 821 reviews earning a near-perfect 4.9-star rating, the company serves McKinney, Plano, Dallas, and surrounding communities including Allen, Frisco, Richardson, and the greater DFW metroplex. Their team of licensed, factory-trained technicians handles air conditioning, heating, and plumbing needs for both residential and light commercial properties.

What distinguishes All Service is their commitment to transparent, flat-rate pricing backed by a 100% satisfaction guarantee. As an American Standard dealer, they install and service energy-efficient systems while offering multiple financing paths including Wells Fargo, Second Chance, and GoodLeap programs. Their 24/7 emergency response means help arrives regardless of hour or holiday. Indoor air quality solutions include air scrubbers, UV lights, dehumidifiers, and duct cleaning, a comprehensive approach that addresses the Texas humidity challenges specific to this region.

Local reviewers consistently name specific technicians who exceeded expectations. Aaron earned praise for explaining system issues in plain language while avoiding unnecessary upsells during a same-day service call. Brian Moore performed a complimentary attic insulation inspection, identifying deficient insulation well below the recommended R-38 level and carefully working around the homeowner's pets. Another reviewer designated Andy as their go-to technician, citing his mastery and efficiency during AC maintenance.
