"Jose Is amazing! I had a previous pool cleaning service company handle my pool and they were no where near as good as Jose. Jose was able to find the leak in my pool when others couldnt. Highly recommended Jose! He makes the pool water crystal clear and clean! Amazing work!"

"After other businesses failed to respond to my requests for help, Commercial Pool & Spa was prompt to respond. It got better from there. Both the office representative and the service technician communicated effectively by phone and text. The tech visited within hours, reviewed the site, quoted the work, and scheduled work for the following day. The tech was delayed but communicated by text to keep me informed. The work was started and completed in a timely manner. The spa now looks fantastic, and I am extremely pleased with the results and the overall experience provided by this service. I'll use them again and can recommend them to others."

"I hired Scott to fix our pool heater. He is very honest and charged me a very reasonable rate to replace the circuit board. He was also able to get our solar heater working again and helped troubleshoot an issue with our dirty pool filter. Highly recommended!"

Pool and Spa Servicing FAQs, answered by experts

To refill a hot tub after winter, start by opening up the tub and giving it a quick cleaning. If you use antifreeze, drain out the water then grab a hose and thoroughly clean the tub shell out, spraying water into each jet of the tub. 

Reconnect the hot tub and turn the power back on. When it’s time to fill the tub again, insert the hose into the filter well (if available). Avoid trapping too much air in the water lines, which can cause the pump to lock up when it starts again. Add the necessary chemicals and start the heating process. It will take some time—most of a full day—for the water to heat up again.

You can drain a hot tub very quickly by using a submersible pump rather than the hose-sized drain at the bottom exterior of the tub. A pump can move up to 30 gallons per minute, draining your hot tub in no time. Using the regular drain can take up to two hours.

When your hot tub is completely dry, there is typically no need to introduce antifreeze into the plumbing. However, if you desire an extra layer of protection against potential freeze damage, you can consider adding some RV antifreeze to your hot tub lines. Just ensure that you use RV antifreeze specifically, as automotive antifreeze is highly toxic and should be avoided.

Generally, it is more cost-effective and energy-efficient to leave your hot tub on all the time rather than turning it on and off. Reheating a hot tub from a cold temperature consumes a significant amount of energy, so maintaining a constant temperature is usually more economical, especially with frequent use.

For daily or weekly use, it's recommended to keep the water at a constant, reduced temperature, such as between 80 and 95 degrees Fahrenheit, and then increase it to your desired temperature before getting in. If you know you won't be using the hot tub for an extended period, you can lower the temperature to save on energy costs. However, if you use it very infrequently, you can turn it off completely, as long as there is no risk of the water freezing.

If water is left inside the hot tub pump over a cold winter, it could freeze and severely damage the pump, water lines, and jets. That can cause leaks, which require very expensive repairs. Freezing or leftover water can stain and damage the hot tub shell, which leads to replacement. Even in mild climates, leaving sitting water in the tub or pipes for a long period of unuse is a bad idea, since disinfecting chemicals fade and the water can develop bacteria, algae, and other big headaches when it’s time to use the tub again.
