"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."

"Scott just came out to service my pool heater, which wasn't working. My pool man said he didn't know why the heater wasn't working and to call a professional. I have been paying my poolman to clean my pool filter every other month. Scott came out and in seconds diagnosed that the pool filter was very dirty, needed cleaning and that's why the pool heater wasn't working. In less than 1/2 an hour he cleaned the filter and had the heater up and running! Obviously, I need a new poolman! Another plus: Scott came out and then gave me the estimate, vs. 2 other firms, which both mentioned $$ up front before coming out and assessing the situation. One of these companies quoted $430 to come out and repair the heater, sight unseen - unbelievable! Scott is professional, reliable and extremely honest. When I need pool work, he's the one I am turning to, without a doubt. Thanks so much, Scott!"

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.

Follow these general safety tips for spas and hot tubs:

  • Keep your exterior electrical receptacles covered and dry, especially around your hot tub and pool during periods of use.

  • Make sure you have a GFCI (ground fault circuit interrupter) properly installed to ensure no one gets accidentally shocked or injured by electrocution. 

  • Don’t use the hot tub or your pool during a thunderstorm. 

  • Before using the hot tub, have a certified electrician thoroughly inspect your hot tub and its wiring to make sure you’re in full compliance with all applicable local building codes. 

A compact unit designed for two to three people typically weighs approximately 500 pounds in its empty state. On the other hand, a larger hot tub meant for up to six people can weigh around 1,000 pounds when empty. Materials used also impact weight. Less expensive hot tubs are typically lighter because they are made of molded plastic or fiberglass.

Where you drain a hot tub largely depends on local regulations, but you must not drain chemically treated water where it can damage the environment. Direct the water toward a sanitary sewer drain that will take it to a treatment facility. If your lawn has a dedicated drainage area that’s free from plants and foundations, you can likely drain it there. Avoid storm drains, as the hot tub water will enter waterways and could hurt aquatic life. Likewise, do not pour it out directly on any public land or where it can get into your neighbors’ property. 

Hot tub heaters typically last seven to 10 years, though some might only last five years if not properly maintained. You can maximize your hot tub heater’s lifespan by ensuring the water’s pH level is properly balanced.
