"This company was extremely responsive and professional.  Marc was very knowledgeable and worked hard to get warranty coverage for my repair and to get my family back in our home quickly, as we had to leave due to no a/c during a heat wave. I met with him at 11:00 and there was a new unit installed by 4:00 that afternoon.  I would highly recommend this company."

"We built our house 20 years ago. We discovered the master bathtub was leaking to our family room. Glenn tried to just reseal the drain but found our builder used the wrong materials and didn't properly configure it. Glenn apologized for having to cut the ceiling to get to the pipe that needed to be replaced but finished the repair quickly and cleaned up everything. I would definitely recommend Glenn at Hosack Plumbing to anyone needing plumbing help."

Customers say: Quick response

"We hired Master Remodel & Construction after our master bathroom, kitchen and garage suffered major water damage after an interior flood caused by an overflowing toilet. Brian Inkley (owner) and Jacob Quick (project manager) have a team of dedicated, talented professionals. They did a superb job in restoring our damaged house. They are a busy team of workers who kept us appraised of their availability for the various stages of our restoration. For the repairs that they didn't do themselves they had excellent recommendations for the professionals we needed such as the carpet installation, closet system installation, kitchen cabinets and the refinishing of our hardwood floors. They seem to be in demand, working at several projects at the same time but we always felt that we were their top priority. Jacob worked with our homeowners insurance adjuster to be sure that the funds allocated for our losses were enough to complete our projects. We recommend Master Remodel & Construction with pleasure."

Humidifier Repair questions, answered by experts

Whether you’re facing significant humidifier repair costs or it’s time to replace your humidifier altogether, it’s understandable to question whether the expense is worth it. Still, there are many benefits of whole-house humidifiers that you might miss, including improved indoor comfort, improved breathing and sleep, better hair and skin, and even increased home value. Either way, the answer is subjective, so it’s helpful to evaluate your home’s humidity without the unit running and give it a few weeks to see if you notice a difference.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

The life expectancy of a humidifier is around ten years on average, but this can vary depending on factors such as usage, maintenance, and the quality of the unit. To help your humidifier last as long as possible, it's important to regularly follow the manufacturer's instructions for cleaning and maintenance.

Several styles of HVAC dampers exist, some with motors and some without. The various types include butterfly, blade, louvered, guillotine, and more. The names describe their construction style and how air moves through them. Motorized versions work through wiring connected to a control panel within the HVAC system. Manual versions allow an operator to decide which way to send the airflow and make the adjustment by hand. 

Whole-house humidifiers work, but the home itself determines their efficacy. If you have a drafty house or an old home with wooden floors that leak air and moisture, the humidifier must work much harder to keep moisture levels constant. Because of this, we recommend doing an air test of your home to determine the best type of humidifier and any work that needs to be done to install it.
