"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."

"Nick G. Is professional, punctual and friendly. I had a leak coming from the kitchen sink and draining to my basement. This leak would have rotted the floor and caused considerable damage. Upon discovering this , I contacted my son, Clint Ehman, an electrician for Hoffman, to get a referral . Nick G. came out today, diagnosed the problem and fixed it. Nick fixed the problem and made my day so much better. The cost was fair and the work he did is exceptional. A shout out to a job well done. We will recommend Nick G. to family and friends."

"Steve arrived on time, quickly diagnosed the problem with the water heater, gave me options to fix/replace without trying to steer me to one option or the other, and answered my questions. I opted for replacement and he got the appointment set up for the next day so we wouldn't be without hot water any longer than necessary."

"Our A/C failed during a very hot spell in June 2018 in St. Louis. Many service providers we called would not come. We called Vitt and told Jeff, the scheduler, about our problem: we had an old furnace (>50 years old) and had the blower motor rebuilt recently by Commercial Electric. Jeff gave us his cell phone number should we decide to go with Vitt. When I had the blower motor fixed, it was in the trunk of my car. I called Jeff and he sent Vic out that day. Vic and Dave came and removed the blower motor from the car and carried it into the basement. The J box was missing from the motor, and the wires leading to it had been cut too short. Vic spoke to Commercial Electric to confirm the correct approach to fixing the wiring. He drilled a new hole to compensate for the shortened wires and moved the capacitor to protect it from touching the filters in the furnace. He checked the relay box and made sure that the furnace breaker was working. After the A/C was successfully turned on, Vic and Dave checked the condenser for heat and then hosed it off. Both men were polite and listened to my information on the history of the furnace and its problems. They asked me appropriate questions about previous service companies. They were patient about my concerns and knowledgeable regarding older furnaces. The bill was reasonable for service provided by 2 men."

Humidifier Repair FAQs, answered by experts

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

An evaporator or swamp cooler is a common alternative for small spaces. These coolers blow moist air into a space to help cool it down. They are more affordable than misters and use much less water. However, coolers will not have the same cooling effect as misters, cannot help plants survive the heat, and only reach a small area.

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. 

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

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.
