Frequently Asked Questions
My Lubbock home has low water pressure. What could be the cause, and can Duncan Plumbing fix it?
Low water pressure is a common issue in Lubbock homes and can stem from several causes, including mineral buildup in pipes, a faulty pressure regulator, or a hidden leak. Our technicians perform thorough plumbing inspections to diagnose the exact source. We specialize in water pipe repair and can resolve the problem efficiently, whether it's a simple faucet issue or requires more extensive pipe work, restoring proper pressure to your home.
What is flat-rate pricing, and how does it work for emergency services?
Flat-rate pricing means you receive a clear, upfront cost for the job before we begin any work, eliminating surprises based on hourly labor. This applies to all our services, including our 24/7 emergency calls for HVAC or plumbing issues. For customers on a maintenance plan, we also waive overtime charges for qualifying dire emergencies, providing predictable costs when you need urgent help.
Do you service all brands of HVAC equipment, or only specific ones you install?
Yes, our NATE-certified technicians are trained to service and repair all brands of HVAC equipment. While we are authorized dealers for FAD and Mitsubishi systems for new installations, our expertise extends to maintaining and improving the efficiency and safety of any system in your home, regardless of brand.
