Drain Cleaning

Properly Cleared Clogs in Your Plumbing

Drains & Clogs

Clearing the Blockage, and the Cause

There is a difference between clearing a drain and punching a hole through whatever is blocking it. The second one takes ten minutes and the water runs again, and then you are calling somebody about the same drain in six weeks. Doing it properly means removing the build-up from the pipe wall and then working out why it collected there in the first place.

HMS Heating & Air Conditioning clears drains across Denton County: kitchen sinks packed with grease, tubs and showers that drain slowly, and main lines backing up into the house. We tell you what we found and whether it was a one-off or a symptom of something structural, like a bellied line or roots, so you can make an informed decision rather than a repeat booking.

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 drain cleaning 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

Drain Work Done Properly

  1. Hand checking pipework beneath a sink

    Work Out the Scope

    One slow fixture is a local clog. Several backing up at once usually means the main line, and that changes the approach entirely.

  2. HMS service van parked outside a neighborhood home

    Get in Touch

    Call, text, or message us. Sewage backing up into the house is treated as urgent, not as a next week appointment.

  3. Hand tightening a white sink P-trap connection with an adjustable wrench

    Find the Access

    Cleanouts, traps, and where the line runs. Getting to the right access point is what lets us clear the pipe rather than just poke at it.

  4. Hand feeding a drain snake into a white bathroom sink drain

    Clear the Line

    Cabling or hydro jetting depending on what is in there. Grease and soap need different treatment than roots or a foreign object.

  5. Hand reaching for a shutoff valve on a water pipe

    Check the Cause

    If the line has a belly, a break, or root intrusion, clearing it is temporary. You should know that rather than find out in a month.

  6. Stream of water running from a faucet into a white sink drain

    Test the Flow

    We run the fixture properly and confirm the line takes a real volume, not just a trickle, before we call it clear.

Warning Signs

Signs You Have A Drain Problem

Water draining slowly. The early stage of every clog. A sink that takes a minute to empty is telling you the pipe is narrowing, and it is far easier to clear now.

Gurgling from drains. Air being pulled through standing water somewhere in the system. It often means the blockage is further down the line than the fixture you noticed.

Several fixtures at once. Two or more drains backing up together points at the main line rather than any individual trap. That is a different and more urgent job.

The same drain, over and over. A drain that clogs repeatedly has a cause: a belly in the line, roots, or a fitting that was never right. Clearing it again will not change that.

Smells coming up. Sewer odour usually means a dry trap or a venting problem rather than a clog, and it is worth diagnosing rather than pouring chemicals at it.

What to Expect

What Our Drain Work Covers

Your Home,
Protected

  1. Kitchen and Bath Drains

    Water pooling around a floor drain on black and white checkered tile

    Sinks, tubs, and showers cleared back to full flow rather than opened just enough to drain.

    Schedule a Visit
  2. Main Line Blockages

    Drain pipe laid in gravel along the bottom of a trench

    When several fixtures back up together the problem is downstream, and it needs different equipment.

    Schedule a Visit
  3. Grease and Build-Up

    Undermount kitchen sink and faucet below a window

    Kitchen lines coated with grease and soap get cleaned off the pipe wall, not bored through the middle.

    Schedule a Visit
  4. Recurring Clogs

    Water supply lines exposed inside an open wall

    A drain that blocks repeatedly has a reason. We would rather find it than sell you the same visit twice.

  5. Traps and Venting

    White PVC P-trap under a sink against a tan wall

    Sewer smells are usually a dry trap or a vent problem, which no amount of drain cleaner will fix.

    Schedule a Visit
  6. Honest Assessment

    If the line needs repair rather than clearing, you hear it straight, with the cost of both.

Common Questions

Drain Cleaning Questions, Answered

Should I try a chemical drain cleaner first?

We would rather you did not. They often fail on a full blockage, they sit in the pipe, and they are hard on older pipework and on whoever opens the line afterwards. A plunger and a bit of patience are fine to try. Beyond that, call.

Why does the same drain keep clogging?

Because clearing a clog and fixing the cause are two different things. A line with a belly in it, root intrusion, or a fitting installed at the wrong angle will collect debris again and again. If your drain is on a schedule, it is worth finding out why.

Several drains are backing up at once. What does that mean?

That the blockage is in the main line rather than any single fixture, and it needs attention promptly. When wastewater has nowhere to go it comes back up at the lowest fixture in the house, which is usually a tub or a floor drain.

What is hydro jetting and do I need it?

High pressure water that scours build-up off the inside of the pipe rather than boring a channel through it. It is the better choice for grease-coated kitchen lines and heavy build-up. For a simple hair clog in a tub it would be overkill.

Can tree roots really get into my pipes?

Yes, and on older properties out on acreage it is common. Roots find joints and small cracks, then grow toward the water. Clearing them buys time, but a line with recurring root intrusion eventually needs repair.

Are you a plumber or an HVAC company?

Yes, both in house. Same crew, same phone number, same upfront pricing as our heating and air work.
