"The 3 Mustache Pledge! Schraer Heating and Cooling deserves every bit of praise I can give! I called them about a worrisome noise coming from my system — one that I could only describe through a few rather vague and comical sound effects. Despite my less-than-technical explanation, their technician quickly understood exactly what I meant, found the issue, and had it fixed in no time. Their professionalism, responsiveness, and ability to solve the problem so efficiently (and with good humor!) made the whole experience stress-free. I’m so grateful for their excellent service and expertise. Highly recommend Schraer Heating and Cooling to anyone looking for honest, skilled, and friendly professionals! I will definitely keep my maintenance agreement in full force and effect!"

Humidifier Repair questions, answered by experts

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

It improves air quality, prevents dry skin, protects wood furniture, and enhances overall comfort.

There are some physical signs you need to have a humidifier that manifest as signs in your home and body. For the home, Watch for cracked and peeling paint, dry wooden flooring and furniture, excessively loud creaking wooden floors or doors, and an increase in the electricity needed to cool or heat the home. Physical symptoms include frequent dry air passages, Scratchy throat, increased allergy symptoms, and dry eyes. 

Regularly clean or replace filters, check humidity levels, and descale water reservoirs.
