Recommended Customer Reviews

Water heart burst, made a call in a panic they told me what to do until they could get there the next morning. The next morning a tech showed up with a smile and didn't leave until he finished the job and made sure I knew how to work the new one.
I will call them again

Water heater leaked, Justin g came the same day within three hours and had the old one replaced same day. Very professional. Competitively priced. Highly recommend!

Got a quote that was very reasonable. Got a new water heater installed very quickly and they took the old one off my hands.

I had a great experience with Water Heaters Only. Our water heater at a rental property was just coming up on its expiration date and we wanted to replace it to ensure we didn't have an emergency issues when it went out.
The company was super quick to respond to setup an appointment and had tons of availability. They arrived on the day of, assessed the type of water heater that was needed and grabbed the correct parts from their inventory. It was all corrected and back to functioning within a day.
In researching similar replacements, the price they quoted was competitive and fit within our budget.

We just purchased a new home and it came with an aging and unsafely installed water heater. John B in San Diego saved the day! He replaced the water heater, updated our gas line and removed uncoded piping. I'm so glad we found this company and highly recommend this company. (Veteran serviceman too!)

This is our second time using Water Heaters Only. They responded quickly and sent a technician out the next day. Clayton Young did an outstanding job and is an absolute pleasure to work with. He went above and beyond to replace our leaking water heater and bring everything up to code. He kept me posted on his arrival time, explain everything he was doing, and even let me record a video of how to relight the pilot. I would definitely ask for him again should we have water heater issues.

Water Heaters Only was great! One call and less than an hour later, they sent a tech out with a replacement. The technician Justin G. was prompt, thoroughly explained all my options and the proposed job, and got it all installed in just under a couple more hours. I highly recommend WHO, was a stress free experience all around - thank you!

I called Water Heaters Only since my pilot light went out. Over the phone I was told my water heater needed to be replaced. The guy on the phone said my water heater was too old to be fixed. I called another repair person (see my other review) and had it fixed within 10 minutes. If there has ever been a company who only wants to charge you the most, and or take your money, Water Heaters Only is that company.

Paul is a great guy! Our water heater stopped working and I called Water Heaters Only. Paul answered the phone, diagnosed the problem, told me what was wrong, and helped me to quickly fix it and reset and start the pilot. He did all of this over the phone! I really appreciate his honesty and help. The water heater is working now, but I will definitely call Water Heaters Only for any future problems. They are very friendly, courteous, and helpful. Many thanks to Paul and Water Heaters Only!

First of all, they lied about taking photos beforehand. The install caused water damage, wall damage, stair damage, and door damage. They then continued to lie about the fact they had taken these photos. If they did, where are they? They don't exist. I however, have over 26 photos of the damage they did cause. Second, the ""manager"" is a huge douche who's only job is to deny and lie.
Don't use this company whatever you do. They do poor work and then refuse to take responsibility of the damage they caused.
