"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."

"Absolute Pool Resurfacing did a fantastic job. I had interviewed 3 companies to resurface my pool and I definitely picked the right one for the job. They are the best..The work was done professionally and in a timely manner. The price was very fair. We also had tile work done on spa wall and coping repair, also had them back to clean entire pool and spa tiling and it looks like a brand new pool.. if you want it done correctly Noe,Chris and his crew are the best.. I highly recommend this company"

"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

Yes. If you test the water and the alkalinity is too low, you can raise it by adding an alkalinity increaser, which likely came with your hot tub’s chemical kit. In a pinch, you can use baking soda to raise the hot tub’s alkalinity. Raising the alkalinity will prevent the hot tub water from becoming too acidic.

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.

In most cases, it is safe to clean a hot tub with vinegar. You will want to verify that your hot tub manufacturer lists vinegar as a safe cleaning product; however, given that vinegar is chemical-free, cleans, deodorizes, and is safe for people and pets, it is usually a good option. You can use vinegar to clean the hot tub shell, interior and exterior spa surfaces, hot tub jets, hot tub filter, and other parts. It is considered a strong, safe, and natural cleanser that can kill bacteria, remove mold and mildew spores, erase water spots, and remove hard water stains.

You can and should use a hose to fill a hot tub. There shouldn’t be anything special about the hose other than it shouldn’t be damaged. Kinks or leaks could slow down the filling process. Attach the hose to the nearest spigot and get the water flowing.

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.
