Gas Piping
The One Job Where Close Enough Is Not
If you can smell gas right now, stop reading. Leave the house, take everyone with you, and call your gas provider from outside. Do not flip switches, do not use the garage door, and do not go looking for the source. That call comes before ours, every time. Everything below is about the work you plan rather than the emergency you are in.
HMS Heating & Air Conditioning runs and repairs gas piping across Denton County: a line to a new range, a stub for an outdoor grill or a fire pit, a pool heater, a generator, or capping a line off properly when an appliance is removed. We have been doing gas work on furnaces since 2015, so this is the same discipline applied to a different end of the pipe. Every line we touch is pressure tested before it is signed off.
Choose HMS
Built on Honesty, Since 2015
HMS Heating & Air Conditioning was founded by Gary Hays, a North Texas native who served in the Marine Corps as an aviation electrician.
He earned his HVAC license in 2015 and built the company on a simple standard: explain the problem, lay out your options with prices, and only then pick up a tool. That's how we handle every gas line job across Denton County, and it's why so many of our customers come from referrals and stay for good.
And if it turns out you don't need the expensive fix, we'll tell you that too. Honesty, integrity, and a reasonable price have been the standard here from day one.

Our Process
Gas Work Done Properly
-
Safety First
If there is any smell of gas, the house gets cleared and the provider gets called before we do anything else. No exceptions.
-
Get in Touch
Call, text, or message us for planned work. For a suspected leak, call your gas provider from outside the house first.
-
Plan the Run
Where the line goes, what it feeds, and what it has to share with. Undersized pipe starves appliances at the far end.
-
Size It Correctly
Total demand across every appliance on the line decides the pipe diameter. This is arithmetic, not a judgment call.
-
Install and Support
Correct materials, properly made joints, sediment traps where they belong, and the run supported rather than hanging.
-
Pressure Test It
The line is pressure tested and held before anything gets connected. That test is the whole point of the job.
When You Need Us
Gas Work Homeowners Ask For
A line for a new appliance. Moving to a gas range, adding a dryer, or fitting a tankless water heater all need a properly sized run to reach them.
An outdoor stub. Grills, fire pits, and pool heaters are the most common outdoor gas runs we install, and they need to be done for exterior use.
A standby generator. Generators pull a large volume when they run, and they frequently need a bigger line than the existing system was built for.
Capping a line off. When an appliance is removed the line has to be capped correctly. An abandoned open line is exactly what it sounds like.
A pressure test. Sales, remodels, and reconnections often need a documented test. It is also the honest way to settle whether a system leaks.

Common Questions
Gas Line Questions, Answered
I think I smell gas. What do I do?
Leave the house immediately and take everyone with you. Do not flip any switch, do not use a phone inside, and do not open the garage door with the opener. From outside, call your gas provider. They come out for suspected leaks and they come out fast. Call us afterwards, once it is safe.
Can I run a gas line myself?
Please do not. Gas piping is licensed work for good reason, and the consequences of a bad joint or an undersized run are not the same as with a water line. It also has to be permitted and pressure tested, and unpermitted gas work causes real problems when you sell the house.
Can you add a gas line for a grill or fire pit?
Yes, and it is one of the more common requests we get. It saves ever swapping a propane bottle again. The run has to use materials rated for outdoor use and needs an accessible shutoff at the appliance end.
Why does my new appliance need a bigger line?
Because pipe size is determined by the total demand of everything on the run, not by the fitting on the appliance. Adding a tankless water heater or a generator to a system sized years ago for a furnace and a range will starve something at the far end.
What is a pressure test and do I need one?
The line is charged with air and held at pressure to confirm nothing escapes. Any new run gets one before it is connected. Existing systems get tested after a suspected leak, during a remodel, and often when a property changes hands.
Do you handle gas for both plumbing and heating?
Yes, and it is the same skill either way. We have worked on gas furnaces since 2015, so gas piping, sizing, and pressure verification are already what we do every winter.
