Day or night, if you have a problem with your water heater, we’ll be at your door as fast as humanly possible. Our official window is 4 hours, but depending on where you live, it can be a little as 20 minutes.

We pride ourselves on being friendly experts (you can learn about our licensed repair experts here) but still being able to explain the problem in terms anyone can understand.

We repair any make or model of hot water tank or tankless water heater in Mississauga, Brampton, Vaughan, Milton or Oakville (here’s a map of our service area).

Clear-cut Prices and Satisfaction Guaranteed

Once we know what the problem is, we provide you with a flat-rate price to make the repair, so there’s no guesswork or hourly rates.

Call us 24/7: 905-457-4425

We back our repair work with our guarantee.

I would highly recommend this company. We had an issue with our tankless water heater and had no hot water… The issues were corrected efficiently and effectively. The technician was professional.

Dr HVAC’s Certifications

Since 2008 when we first opened our doors, Dr HVAC has worked hard to earn the trust of the people of the Toronto area. Here are some of the third-party organizations with which Dr HVAC is accredited.


There are so many reasons to choose Dr HVAC when you aren’t getting any hot water or are experiencing other issues.

We Can Repair Any Kind of Water Heater

Whether you have a hot water tank or a tankless heater, it doesn’t matter. Our professional technicians have the expertise to repair your water heater regardless of make, model or age.

You Get Affordable, Up Front Prices

We keep our prices competitive and we tell you what the cost will be before the work begins. There’s no guesswork to do with hourly rates or additional costs.

We Service Your Neighbourhood

You can see the cheerful Dr HVAC vans in these cities of the GTA: Brampton, Mississauga, Oakville, Milton and Vaughan. You can check out our service area map here.

Licensed, Expert Technicians

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.

Satisfaction Guaranteed

100-guaranteeWe’re a small but highly professional team of water heater experts. Because we don’t have the power of a huge national company behind us, we need to make sure every customer is a satisfied customer. We believe in the value of knowing what you’re doing and friendly customer service. If that makes us old-fashioned, we can live with that.

But we also know it’s not enough to say we have great service. That’s why we give you our 100% satisfaction guarantee: if your water heater breaks down again for the same reason we will come back and make sure it’s fixed.
