What Customers Say

“John Park and Nathan did a great job with the air filter, HRV and humidifier today. John is very knowledgeable and was able to answer my questions and make logical suggestions on improving the humidity in the house. Thank you.”

- Jasmine T.

“John Park came to our home as a follow up to a problem I had with my humidifier not working. John provided excellent service, taking the time to share the problem and solution, provide education to help me solve the problem next time and even showed me some tips on how to get the best performance out of my humidifier. That is excellent service. So the problem was the humidifier was set too low. I was following the Manufacturer’s suggestion which was contrary to what was needed. Thanks for the excellent service John. I will continue to use Mersey as I have for so many years.”

- Hilda G.

Frequently Asked Questions

We recommend 30-33%, but preference comes first. Consider that the changing seasons may require higher or lower settings, as well, and that if you are using a humidifier to relieve symptoms of illness, you may want a higher setting.

Anyone who lives with them! Humidifiers provide many subtle health benefits. The most dramatic advantages are for those living with diseases that can be treated with humidity, such as asthma or eczema.

Our humidifiers provide whole-home humidity through your ductwork. Store bought plug-in humidifiers are stand-alone and only provide humidity to a small area of the home.

Our certified technicians are almost always finished with a humidifier installation in 1-3 hours. However, this may vary depending on how large your home is and what type of system you’ve purchased.

Ensure all pathways to potential work areas are clear of tripping hazards, and have your furnace room and other work areas readily accessible, too.
