Casa Mechanical Services is a family-owned HVAC company serving San Antonio, Austin and Central Texas since April 2001. We are proud to deliver honest service, dependable workmanship, and practical plumbing and comfort solutions built around customer trust and long-term value.

 

Family Ownership and Deep Local Experience

Casa Mechanical Services is owned and operated by the W.G. Christianson Jr. family, including George, Lane, and Cody. Our company has served Austin, San Antonio, and Central Texas since April 2001, but our family history in the region and the trades goes back much further. As an HVAC company, we believe strong service begins with personal responsibility, honest communication, and respect for the customer’s home and time. Our leadership team brings a combined 100 years of experience in plumbing, heating, and air conditioning. That background helps us solve problems carefully, recommend practical solutions, and keep the focus on service that feels dependable from the first visit to the final result.

Built on Workmanship, Value, and Customer Trust

Over the years, Casa Mechanical Services has installed high-efficiency mechanical systems in more than 30,000 new homes and replaced many outdated units with modern systems designed for stronger performance and better energy use. Our HVAC company has grown by staying focused on core values that matter to homeowners:

  • Honesty and integrity in every recommendation
  • Competitive pricing and practical long-term value
  • Pride in work completed the right way
  • Background checks for all employees
  • Energy-efficient Go Green solutions
  • Customer-first service built around clear communication

We want every customer to feel informed, respected, and confident that the work being done is the right work for the home.

An HVAC Company That Helps Customers Choose Wisely

One of our goals is to help homeowners understand their options instead of feeling pressured into fast decisions. Casa Mechanical Services believes education is part of good service, especially when comfort systems and plumbing equipment affect both daily life and household budgets. As an HVAC company, we take time to explain what we see, what caused the concern, and which solutions offer the best value based on the condition of the home and equipment. That practical approach helps customers avoid confusion and make choices they can feel good about later. We do not believe in generic sales talk. We believe in honest answers and recommendations that fit real needs.

Recognition, Reputation, and Community Commitment

Casa Mechanical Services has earned recognition from major names in the industry, including Carrier, Lennox, Trane, Lennar, and Pulte Group. We are also proud members of organizations such as the BBB and several community-focused groups throughout Central Texas. Still, awards matter less to us than trust. Our HVAC company continues to serve the region with the same values that helped build our reputation: honesty, strong workmanship, fair treatment, and doing the job right the first time whenever possible. When homeowners choose Casa Mechanical Services, they are choosing a local company with deep roots, practical experience, and a commitment to keeping customers happy through reliable service.

Casa is a great service company for AC and Plumbing. Their techs are the best. I recently had a tankless water heater malfunction and even though they didn't install it originally, they took great care to diagnose and provide options to us. This type of service also applies to my HVAC. If you use Casa, you should consider their services plan which are not expensive and include 2 services checks a year. This is one of the most well-run service businesses I have ever dealt with.

I appreciate the efficiency and professionalism Joseph Martin showed when he came by my home to fix my water heater. He took time to explain everything that was going, allowing me to the room to ask questions.

Absolutely pleased with the next time visit to resolve a lack of hot water issue a home inspector found with my property. The solution wasn’t obvious, and took more work than anticipated, but I have hot water again! Thanks to Joseph for his troubleshooting ability!
