Comprehensive Heating Services

Get emergency repairs the same day

Waiting isn’t an option when your furnace quits, a pipe bursts, or your AC stops cooling. That’s why we provide 24/7 emergency HVAC and plumbing services with no extra after-hours fees and with phone lines open 24/7.

We know Littleton homes inside and out—from old clay sewer lines in mid-century neighborhoods to modern plumbing in newer developments—and we prioritize service calls for the most urgent cases.

Here’s why homeowners choose our plumbers and techs:

  • Fast Response Times – We aim to arrive the same day for all urgent calls.
  • No After-Hours Extra Fees – No surprises, just fair pricing.
  • Certified & Background-Checked Technicians – We never use subcontractors.
  • Trusted Since 1977 – Decades of service mean proven reliability.

Burst pipe or sewer backup? Let us handle it

Littleton’s older homes are more prone to plumbing emergencies, but newer homes aren’t immune—high-efficiency systems and modern fixtures fail, too.

Our licensed plumbers handle:

  • Burst Pipes & Leaks – Prevent flooding and protect your home’s structure. We’re experts in frozen and corroded pipes.
  • Sewer Line Backups – Old clay pipes can collapse, leading to messy, damaging backups.
  • Drain Cleaning & Jetting – High-pressure water blasts away stubborn blockages deep in your plumbing system.
  • Sump Pump Repair & Installation – Keep basements dry during heavy storms and spring snowmelt.
  • Water Line & Faucet Repairs – Stop leaks before they cause more expensive damage.
  • Water Heater Repairs – Our plumbers work on both tank and tankless systems.

Water-related damage costs homeowners over $13,000 per claim! Don’t wait—call a plumber at the first sign of trouble.

Gas leak? Leave it to the professionals

If you suspect a gas leak, that’s a serious emergency—never try to fix it yourself!

Our certified gas plumbers take care of:

  • Leak Detection – We use advanced tools to locate hidden problems fast.
  • Repairs & Replacements – Whether it’s a leak in an appliance, pipeline, or meter, we handle it safely.
  • Furnace & Boiler Issues – We fix gas-powered heating systems with care.
  • Appliance Connections – Stoves, water heaters, and more.

Fix it before the freeze kicks in

Littleton winters are no joke. A broken furnace is more than an inconvenience—it’s a serious home emergency that can lead to frozen pipes, higher energy bills, and health risks.

Our HVAC technicians fix:

  • Furnaces – No heat? We’ll diagnose and fix it fast.
  • Boilers – We specialize in older radiant heating systems common in Littleton
  • Heat Pumps – If your system isn’t handling the cold, we’ll ensure your backup heating kicks in.

Littleton can hit subzero temperatures in winter—don’t wait until your home turns into an icebox.

Repair your AC before the heat wave gets worse

Summer temperatures in Littleton can hit the low 90s, but inside your home, it can feel even hotter. Older adults, young children, and pets are at risk when the AC fails.

We handle emergency repairs for:

  • Central AC – No cold air? We’ll get it running today.
  • Ductless Mini-Splits – Fixing zoned cooling issues for maximum comfort
  • Heat Pumps – Ensuring year-round efficiency in both cooling and heating modes

AC failures spike during Littleton’s heat waves—reach out for fast service!

What to do in a home emergency

 

How to shut off your water when facing a major leak

  1. Find your main shutoff valve – Usually in the basement, near the water heater, or outside your home.
  2. Turn it clockwise – This will stop the flow immediately.
  3. Open a faucet – Relieve pressure to minimize damage to your plumbing
  4. Once it’s controlled, call our plumbers

 

How to reset your furnace if you lose heating

  1. Check your thermostat – Make sure it’s set to heat and the temperature is turned up.
  2. Turn off the power switch – Wait 30 seconds, then turn it back on.
  3. Press the reset button – If your furnace has one, press it once.
  4. Call us if the issue persists or you smell gas.

 

How to deal with a gas leak

First, learn to identify a leak:

  • Rotten egg smell
  • Hissing sounds near gas lines
  • Headaches, nausea, or dizziness

If you encounter any of these signs:

  • Evacuate immediately and call 911.
  • DO NOT turn on lights or appliances.
  • Once safe, call our gas plumbers for emergency repairs
