4 Best Water Heater Services in Denver (2026)

Ranked by real Google ratings and review volume · How we chose

We compared 19 water heater services in Denver on Google Maps · 4 listed · How we rank

A water heater that dies on a cold morning is a same-day problem, and the water heater services in Denver below are all full-service plumbing, heating and electrical houses rather than single-trade shops. Together they hold more than 29,000 Google reviews, each rated 4.7 or higher, so what separates them is how much of that feedback is actually about hot water.

Short answer: Applewood Plumbing Heating & Electric has the most Google reviews here, 4.8 from more than 17,000, with water heater repair and tankless units on its site and a reviewer who had a worn-out heater replaced. Heart Heating, Cooling, Plumbing & Electric and Golden West each have a reviewer describing a new water heater. None of these firms is a water-heater-only shop, so ask about the unit, the warranty and the permit work before you book.

How the scorecards work

Each number comes from public Google data on the date shown. Rating is the live Google star average. Review volume is how many customers have rated the business, compared with other Denver plumbing and heating companies. Confidence weighs the rating by that volume, so a 4.8 from thousands of people counts for more than a 5.0 from a few. Recency reflects how lately customers are still leaving reviews. No business can pay to change these numbers.

What shapes water heater pricing in Denver (2026)

Reviewers on this page rarely name a price for a water heater alone, so there is no honest dollar table to show. The main drivers are the type of unit (tank or tankless), its size, whether the old one has to be hauled out, and extras like a new expansion tank, valves or a pressure regulator. Ask each company for a written, itemized quote that names the unit and the labor.

Water heater help around Denver

These companies work from addresses in Denver, with Heart serving the metro and the Front Range, and one Applewood reviewer describing it as serving the Denver and Boulder area. If you’re searching for a water heater service near me, each listing shows a phone number and directions.

What to ask before a water heater job

Is the quote for a tank or tankless unit, and which brand and size?
Does the price include hauling away the old heater and any permit or code work?
Will you replace the expansion tank, valves or pressure regulator at the same visit?
What is the warranty on the unit and on your labor?
How fast can you get here if the heater is leaking right now?

Frequently asked questions

Do these Denver companies repair water heaters or only replace them?

Applewood’s site lists both water heater repair and tankless water heaters. Doctor Fix-It’s site lists water heater maintenance, repair and installation, plus tankless installation, maintenance and repair. Golden West’s site lists installing water heaters, and a reviewer at Heart describes a new unit going in, so ask the others whether they repair before you commit to a replacement.

Can one visit cover the expansion tank and pressure regulator as well as the heater?

One Applewood reviewer had a new heater installed, the expansion tank moved and a water pressure regulator added in the same job, and a Golden West reviewer had a failed thermal expansion tank replaced and then a heater installed a week later. Ask for those parts on the quote so they are not a surprise.

Which of these companies can come on short notice?

A Golden West reviewer reports a technician arriving within 30 minutes of a weekend call, and a Doctor Fix-It reviewer reports a visit about an hour after calling. Applewood lists daily hours from 6 AM to 10 PM, while Golden West’s site advertises 24/7 support and Heart’s says emergency service is available with 24/7 answering.

The short version

Applewood is a solid first call given its review base and the water heater details its reviewers give. If the heater failed on a weekend, Golden West’s reviews show a fast response. Get the unit, the parts and the warranty written down before work starts.
