Questions and Answers
My older Austin home has rooms that are much hotter or colder than others. What's the most common cause and how can MJZern help?
Uneven cooling, especially in larger Austin homes, is often due to improperly balanced ductwork or dirty condenser coils reducing system efficiency. With my engineering background and HVAC expertise since 1983, I perform a detailed assessment. This includes checking duct design per SMACNA standards, cleaning coils, and ensuring your system is correctly sized and balanced for your home's layout. The goal is consistent comfort and improved energy efficiency throughout your entire house.
You offer both appliance repair and plumbing. If my garbage disposal is leaking, which service do I need?
A leaking garbage disposal often involves the plumbing connections, not the appliance's internal motor. My dual expertise means I can efficiently diagnose the source. I'll check the sink flange, dishwasher connection, and drain pipes to pinpoint the leak. Whether it's a simple gasket replacement or a more involved drain repair, I handle it all in one visit, saving you the hassle of calling multiple specialists.
What sets your approach to a plumbing installation or repair apart, especially for something like a gas line?
My approach combines a Master Plumber's practical skill with a mechanical engineer's focus on system design and safety. For a gas line installation, I don't just follow code—I ensure the entire system is optimized for efficiency and long-term reliability. I treat every job with the same care as if it were in my own home, which means using quality materials and meticulous workmanship. This dual-license perspective provides an added layer of confidence for homeowners.
