Hot tub repairs cost between $200 and $500 on average. You can minimize those costs by maintaining your hot tub and keeping necessary supplies on hand. An elevated shelf in the garage is a great place to store your water care chemicals so that kids and pets will stay safe and you’ll always have them around. 

Your hot tub should be drained of existing water, cleaned, and refilled every three to four months at a minimum. Follow your tub manufacturer’s recommendations for cleaning, and rinse thoroughly when finished to eliminate any residue from the cleaning products. This is also a good time to inspect your tub’s cover in good lighting for any leaks, tears, or other damage that might cause problems. 

Using your hot tub manufacturer’s suggested cleaners and methods, keep your hot tub filters clean to avoid a loss of water heat. This will help extend the filter’s useful life and efficiency. If the filter is more than two to three years old, replace it with a new one and buy a second filter to keep around as a spare.

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.

Whether you can repair a hot tub depends on the severity of the problem and the location. With the right tools and knowledge, you can fix problems like small leaks or switching out a dirty filter. However, electrical and plumbing issues require a licensed professional due to the inherent risk, particularly when mixing water with electricity.

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.
