"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

Practice makes perfect, and Varsity has been at it for over half a century!

Varsity’s mission has always been clear: to serve our neighbors with integrity, solve home service challenges with innovative solutions, and provide lasting results. Our dedicated crew is background-checked, rigorously trained in the latest technology, and excited to exceed your expectations.

"Efficient and clear process, nice crew, quick and clean execution. It would score 4.5 as there were a couple of opportunities for improvement identified (including surprising problems with running a communication cable, and a trivial unnoticed misconnection sorted out the next day by a dedicated technical help call), but overall an outstanding service."

Water Heaters questions, answered by experts

If you're replacing a broken water heater, now is a great time to make sure you're selecting a unit that has the right capacity for your household. According to the U.S. Department of Energy, a small 50-gallon to 60-gallon tank is sufficient for households with one to three people. A medium-sized 80-gallon tank is considered ideal for three to four people. A larger tank may be needed if your household has four to six people.

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.

Gas water heaters last between eight and 12 years on average. You can help them reach their maximum lifespan with regular cleanings, maintenance, and professional checkups, though don’t hesitate to swing for a full replacement if the total cost of repairs is greater than that of purchasing and installing a new unit. 

Basements, specifically those without any air conditioning, are the best location for a hybrid water heater. These rooms are less likely to experience extreme temperature fluctuations, which can affect your hybrid water heater’s efficiency and performance. Basements often have more than enough space for their tanks and proper air circulation. Hybrid water heaters can also be a bit noisy, but putting them in your basement will keep the noise away from your main living areas.

Replacement should be considered when repair costs exceed half the price of a new unit, if the heater is more than 10-15 years old, or if consistent issues hinder its effective functioning despite multiple repairs.
