Does my HVAC technician have to be NATE certified?

• <div><p>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 <a href="https://www.angi.com/articles/common-types-of-HVAC-systems.htm">different types of HVAC systems</a>, 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. </p></div>

Q: What are the benefits of a central humidifier?

• <div><p>It improves air quality, prevents dry skin, protects wood furniture, and enhances overall comfort.</p></div>

Q: What is included in an HVAC service call?

• <div><p>Most HVAC service calls include diagnostic fees, which could include checking on a specific issue you&rsquo;re experiencing or running through a routine inspection checklist. If you called for a particular problem, the service call will also include an estimate to fix the issue, including materials and labor. Depending on your HVAC technician and the service you requested, you might also get a general inspection of your system components to ensure everything is working as intended.</p></div>

Q: When should you not use a dehumidifier?

• <div><p>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. </p></div>

Q: What is the difference between a manual damper and a motorized damper?

• <div><p>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. </p></div>

Marco is professional and responsive, and his work is very good. WE hired Penagos Painting to completely repaint the interior of a house and its garage that we had just purchased. They did a really good job covering the awful paint on our textured walls, and repainted the trim and doors in...

They did an excellent job. Had to have a couple things repaired that was caught in the home inspection. The job was quick. The cost could always be cheaper but I was only charged a service call.

What really sold me on this shop was the courtesy I was given by the employee's. I did not talk to the repair man until the next day. What blew me away that they did not charge for the service. I will take the machine back if I have any problems. I will also delight in shopping at this store.
