Water Heater Installation & Replacement in Greenville, SC

Upgrade to a reliable, energy-efficient water heater with expert installation from Greenville's trusted home services team.

Whether your old water heater has failed or you're upgrading to a more efficient system, First Class Heating & Air provides professional water heater installation throughout Greenville and the Upstate. We install both traditional tank and tankless water heaters to fit your home's needs and budget.

Traditional tank water heaters remain the most common choice, offering reliable hot water at an affordable price point. We install gas and electric models in sizes ranging from 40 to 80 gallons, properly sized for your household's hot water demands.

Tankless water heaters are growing in popularity in Greenville for good reason. They heat water on demand, meaning you never run out of hot water, and they're significantly more energy-efficient than tank systems. Tankless units also last 15-20 years compared to 8-12 years for tank models, making them a strong long-term investment.

Every water heater installation includes proper sizing for your household, professional installation to code, all necessary plumbing and gas/electrical connections, old unit removal and disposal, and a thorough performance test.

Financing is available to make your water heater replacement affordable. We'll help you choose the right system and the right payment option.

Frequently Asked Questions

Should I get a tank or tankless water heater?

Tank systems cost less upfront and work great for most Greenville homes. Tankless systems cost more initially but provide unlimited hot water, use 30 to 50 percent less energy, and last nearly twice as long (15 to 20 years versus 8 to 12). We help you decide based on your household size, hot water usage patterns, and budget.

How long does water heater installation take?

Most tank water heater installations take 2 to 4 hours. Tankless installations may take 4 to 6 hours depending on whether additional plumbing, gas line upgrades, or electrical work is needed. We handle everything including old unit removal and disposal.

How long do water heaters last?

Traditional tank water heaters last 8 to 12 years with proper maintenance. Tankless water heaters last 15 to 20 years. Regular flushing and anode rod replacement extends the life of tank models significantly. Homes on well water should flush more frequently due to mineral buildup.

What size water heater does my Greenville home need?

Sizing depends on your household size and peak hot water demand. A family of four typically needs a 50 gallon tank or a tankless unit rated for 2 to 3 simultaneous fixtures. We evaluate your specific usage patterns during our free assessment to recommend the right size.

Do you offer same-day water heater replacement?

Yes, we offer same-day emergency water heater replacement when stock is available. If your water heater has failed and you need hot water restored quickly, call us and we will prioritize your replacement. We carry the most common tank sizes on our trucks for fast turnaround.
