When you hire Dr HVAC, you get a fully licensed, certified technician who’s friendly and polite. Our technicians are great with people as well as experts, and will provide an explanation about what’s wrong with your water heater in simple terms anyone can understand. We have a strict alcohol and drug-free policy for your safety and ours. You can meet our technicians and learn about our ongoing training here.

Guaranteed Repairs

We give you the added protection of our 100% satisfaction guarantee. That means if the same issue happens again, we’ll come back and fix it for free.

No Pressure to Buy Anything You Don’t Need

Our technicians are there to make the repairs you want, not sell you things you don’t need. If your water heater is older it may be more cost-effective to consider replacing, but you won’t get pressure of any kind.

Your Home Will Look Just As Good After We’re Done

Part of our job is to protect your home while we’re working. We wear protective foot coverings and/or lay down protective mats in your home. Once we’re done working, we clean up the area around your water heater and remove any broken parts. Where possible, we take the materials in for recycling.

To make sure everything goes according to our high standards, a member of our customer service team will follow up with you after the appointment to ensure everything is working well and you are happy with our service.

Water Heater Maintenance

Yearly maintenance on your water heater gives back:

  • Efficiency: when your water heater is clean, you’ll get more for your energy dollar.
  • Safety: you’ll ensure there’s no deadly carbon monoxide in your home.
  • Reliability: you’ll avoid most breakdowns and emergency repair costs.
  • Durability: you’ll help your water heater last longer.

Dr HVAC provides comprehensive inspection and tune up services for your water heater with a written report. Best of all, we provide a satisfaction guarantee on our maintenance services, just like we do on all our services.


So What Happens in Your Maintenance Check?

We give you a water heater that’s as close to brand new as possible with checks and adjustments like:

Removing Hard Water Scale

Minerals in our water coat the inside of pipes, reducing heating efficiency.

Checking for Soot Buildup

Combustion byproducts can build up in the vents – that’s a fire hazard.

Flushing Out Sediment Buildup

Our water supply contains fine particles of sand and dust that build up into sludge. Yuck!

Checking Vent for Blockages

This can mean deadly carbon monoxide backflows into your home.

Checking for Signs of Corrosion

When corrosion takes over, parts can fail.
For tanks, it can mean the bottom falls right off.

Checking for Leaks, Large or Small

Once they start, they only get bigger, and can eventually lead to water damage.

Checking the Air Supply and Gas Line

The combustion process requires oxygen and fuel – and the last thing you want is a gas leak.

Inspecting the Burner

Ideally we want to see a nice, steady blue flame.
