"Ryan came to house and reviewed our needs and what was available. Everything was explained to us so we understood what was to be installed and what what future services we would need (filter changes and when to expect the need to change filters). The filter system was installed the next week and was done in a professional manner. We would definitely recommend them for water filtration needs."

"A different company gave us a quote for $500 to clean the condenser and $2500 to recharge it to check for leaks, so we were dragging our feet. I decided to get another opinion and found Comfort Doctor. They were incredibly responsive and came the next morning. They cleaned the unit for $65 and recharged the unit right then and there with 1 lb of refrigerant. Now it is working great for ~$300. The technician gave us recommendations as if it were his own home and said the quick and inexpensive fix is where you should start. We might not need to do the more expensive leak-check at all unless the system continues to leak substantially."

"Zach Brown initially came to fix leaking water situation and then realized there was damage due to water seepage. After that damage is repaired, Zach will return to put plumbing back in order, including replacing faucets which had to be cut out to allow removal of granite countertop, reconnect water lines and possibly reinstall a new Reverse Osmosis system since the old one had to be removed. Can't say enough about Zach -- his professionalism, his explanation of what's being done and options for replacing/improving plumbing under kitchen sink, pipes, etc."

"Angel was exceptional, professional, efficient, clean and responsive to every request, fixed numerous issues related to my toilets, noticed a flooring issue that we are now addressing and diagnosed a water heater issue that had been attributed falsely to a foundation issue saving us thousands. They are expensive compared to many but worth every penny we spent."

Water Softeners FAQs, answered by experts

A water softener removes minerals from your drinking water and can make your house water softer. These softeners are designed to extend the lifetime of your plumbing system while also making water safer and more palatable for drinking. Hard water, which is water with a heavy amount of suspended particles, can also cause hair damage, skin irritation, and buildup in your pipes.

Yes. To get soft water, you can install a water softening system, which will replace the calcium and magnesium ions in the water with sodium or potassium ions. Water softeners cost anywhere from $200 to $6,000, depending on the size and complexity of the system. You can either install a water softener for the whole house or just at your shower heads. If you’re sensitive to sodium or potassium, you can install a salt-free water conditioner.

Water purifiers and water softeners serve different purposes, so the best one will depend on your particular needs. Water purifiers remove contaminants from water (such as bacteria, viruses, and chemicals), leaving you with ultra-clean and safe water. However, water softeners remove minerals from your water so that the water doesn’t leave stains around your house or cause plumbing problems.

The primary difference between a water softener and a water filter lies in what they remove from the water. A water softener is designed to remove hard minerals like calcium and magnesium. In contrast, a water filter has a broader effect, removing various contaminants above a certain size, which can include bacteria and other impurities.

To decide which you need, consider your goal. If you want to eliminate hard minerals, choose a softener. If you want to remove a wide range of contaminants, a filter is the better option. Filters are also generally less expensive to install. Depending on your water supply, you may need to install both for comprehensive treatment.

The most accurate way to determine whether you have hard water is to purchase a water test kit from a hardware store or send a tap water sample to a lab. But there are some signs you can look out for without professional testing. For instance, if you're consistently dealing with mineral stains on your glassware, windows, and shower doors, you're likely to have hard water. Hard water can also make it harder to lather and rinse soap, so if you're struggling to work up a good lather in the shower, hard water might be the culprit.
