Pool Heater Installation and Repair in Annandale, VANew heaters installed, old ones repaired
A pool heater gets you into the water weeks earlier in the spring and keeps you there into the fall. We install new pool heaters and repair the ones that will not fire.
Signs the heater needs a look
- The heater will not light
- It lights, then shuts off
- The water never reaches the set temperature
- An error code on the display
- Rust flakes or soot around the unit
- Water dripping from the heater
- It short cycles on and off
- The heater is past its years

Pick the right kind of heater
A gas heater warms the water fast, which suits a pool you heat now and then. A heat pump costs more up front and less to run, which suits a pool you keep warm all season. We walk you through both.
Sized for your pool
A heater that is too small runs all day and never catches up. We size the new one to the pool, the spa if you have one, and how warm you want the water.
Thinking about a heat pump?
See heat pumps for pools for how they work and when they make sense.

- How long does a pool heater last?
It depends on the unit, the water chemistry and how it has been looked after. Water that is out of balance shortens the life of any heater.
- Why does my heater start and then shut down?
Low water flow is the most common cause, often from a dirty filter or a pump problem. The heater shuts itself off to protect itself.
- Can you heat an attached spa too?
Yes. Tell us how the pool and spa are set up and we will size the heater for both.
