Mr. Polzin showed up right away when I called him for a leaking boiler system. Not only was he prompt, he was very friendly and willing to fix the problem. After a quick repair of a faulty valve, everything was back to normal and we had heat again! Will absolutely use him again.

Humidifier Repair questions, answered by experts

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.

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.

Cleaning and replacing filters and ducts reduce allergens and enhance air quality.

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

During your HVAC preseason maintenance call, your contractor will inspect the system for any problems and make small adjustments for better efficiency. Tasks include, though are not limited to:

Changing filters
Checking the thermostat
Clearing away dust and debris
Checking for mold
Inspecting electrical elements
Inspecting condensate lines and drain
Cleaning evaporator coils
Ensuring ignition function

While you can do some of these services yourself, hiring a professional to keep HVAC equipment running can be helpful. These experts know what to look for and may be able to spot potential issues before they become problems. Many HVAC companies offer annual maintenance plans.
