Tankless Water Heater Installation in Florence

One Licensed Contractor for Every Part of the Installation

Most water heater installations uncover something extra: an undersized gas line, a venting issue, or an electrical panel that needs attention before a new unit can go in. When that happens with a single-trade company, you’re scheduling a second contractor and adding days to the job. As a licensed HVAC, plumbing, and electrical contractor serving Florence, South Carolina since 2003, Quality Service Company handles every piece of a tankless water heater installation in a single visit. Gas, electrical, and venting: our team is trained across all three trades.

Why Florence Homeowners Choose Quality Service Company for Tankless Installation

Our entire team is background-checked and drug-tested, and our HVAC technicians hold NATE certification: the leading third-party credential for HVAC technicians, awarded to those who have been tested on the skills the job actually requires. Our plumbing and electrical work has been voted Best of the Pee Dee by the community we’ve served for more than two decades.

We back every installation with a 100 percent Satisfaction Guarantee and provide upfront, flat-rate pricing so the cost is agreed on before work begins. No surprises when the invoice arrives. And because plumbing issues don’t follow business hours, we’re available around the clock for Florence-area homeowners who need help fast.

The practical advantage of our multi-trade model matters most during installation. If we find a gas supply line that needs upsizing, a venting configuration that requires modification, or an electrical panel without the capacity for an electric tankless unit, we can address it on the spot. One company, one visit, one call to (843) 920-2004.

What Our Tankless Water Heater Installation Process Covers

A proper installation starts with sizing. The right unit depends on your household size, the number of bathrooms, and how many fixtures may be drawing hot water at the same time. A unit too small for the demand may struggle to keep up, so we assess your usage before recommending a system.

We install both gas and electric tankless systems and help homeowners weigh the differences:

• Gas tankless units require an adequately sized gas supply line and proper exterior venting. Older homes in the Florence area sometimes need gas line upgrades to support a tankless unit’s higher BTU draw.
• Electric tankless units require sufficient electrical panel capacity. We evaluate your panel as part of the installation process and handle any necessary upgrades in the same visit.

Every job is priced upfront before we begin, including any supporting gas, electrical, or venting work.

Tankless vs. Storage Tank Water Heaters

Traditional storage tank water heaters keep a large volume of water heated continuously, consuming energy even when no one is drawing hot water. Tankless units heat water on demand: cold water flows through the unit, gets heated instantly, and arrives at the tap without waiting for a tank to refill or reheat.

The physical footprint is another difference. Tankless units are compact and wall-mounted, freeing up the floor space a 40- or 50-gallon tank currently occupies. For Florence homes with limited utility closet or basement space, that’s a meaningful gain.

One consideration worth planning for: homes with high simultaneous demand, such as multiple showers running alongside appliances, need a unit sized to match. We account for this during the assessment so the system is aligned with household demand after installation. Routine maintenance, including annual descaling to prevent mineral buildup, helps support a tankless unit’s efficiency over the long term.

Financing & the Quality Service Membership

Tankless water heater installation is a meaningful investment. We offer flexible financing through Wells Fargo and GreenSky to make the project manageable without delaying an upgrade your home needs.

Our Quality Service Membership (QSM) is a proactive maintenance plan designed to support equipment life, lower utility bills, and provide priority scheduling. For a tankless water heater, that means your system gets the regular attention, including descaling, that supports your investment over time.
