Claim This BusinessDilmak Services Heating, Air Conditioning, and Plumbing has anchored itself in San Antonio for over 30 years as a family-owned operation. The company holds 380 customer reviews averaging 4.8 stars, reflecting consistent service delivery across the city's neighborhoods. Offering 24-hour availability every day of the week, Dilmak serves residential clients throughout San Antonio and surrounding Texas communities, handling everything from emergency cooling repairs to complete system installations and plumbing needs.
What distinguishes Dilmak from other San Antonio contractors is their multi-brand expertise and commitment to cutting-edge solutions. As an authorized dealer for Ruud, York, and Samsung systems, they offer homeowners access to major equipment manufacturers with full warranty support. Their duct cleaning service addresses a frequently overlooked contributor to poor indoor air quality, while their blown-in cellulose insulation provides 22% greater efficiency than traditional fiberglass batts, a meaningful upgrade for San Antonio's extreme summer temperatures. The company also provides upfront pricing across all services, eliminating the guesswork that frustrates homeowners facing unexpected repair bills.
Reviewers consistently highlight specific technicians who went above and beyond. When Nicole Miller's AC problem stumped multiple other contractors, technician Anthony diagnosed and resolved the issue across several visits while charging only for the initial call. Vangie Reyes praised Joseph Munos for his thorough maintenance work, including photographs explaining areas of concern. Heather Hays described how Dilmak spent a year researching and sourcing parts to replace her vent hood motor when no other company would take on the job. Codi earned mention for educating homeowners on system maintenance while respecting their property.
Every reviewer names a specific technician, with Anthony appearing in three positive reviews for solving problems other contractors missed. Multiple customers note fair pricing and the maintenance program as reasons for loyalty, while others praise the 24/7 availability during San Antonio's brutal summer heat waves.
