"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, but only if it is a freshwater tub (not saltwater) and if you make sure the chlorine and bromine levels are below 1 ppm.

When your hot tub is not in use, you can keep it at a constant soaking temperature of around 100 degrees Fahrenheit. For extended periods of non-use, you can lower the temperature by about five degrees. This slight decrease makes it easier and quicker to heat back up to a desirable level when you're ready to use it again. Additionally, you might consider lowering the temperature by a couple of degrees during the summer to avoid feeling overheated.

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.

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.

Algae-related green hot tub water is generally safe to use, as algae aren't usually harmful to your health. However, if the conditions in the hot tub are hospitable to algae growth, they may also be hospitable to the growth of other types of microorganisms, including Pseudomonas aeruginosa, bacteria that can cause hot tub rash, or Legionella bacteria, which can cause respiratory illness.
