"Jeff has come to the rescue twice to my new build home. He came the first time in the middle of summer when the a/c would start up. It was just the fan running. He was able to repair the unit same day. Recently, the same thing happened but with our heater. The burners were not lighting up. Apparently the builders never put the cover on and they got clogged with dust and debris. He was able to get our heater working and cannot be more thankful. He was able to fix a couple of things in the attic that the builder just slapped on. I’m sure this system will not stand the test of time, especially here in Vacaville so I’ll trust New age when it’s time to replace this system"

"Enrique Pelayos did a great job refurbishing our cat tower. We've had the tall tower for years and its like a family heirloom for all our cats. The job was more difficult because we wanted a high-traffic, tough to shred, carpet put on it. Enrique did a beautiful job and it looks like it is brand new. The cats love it and are going crazy scampering up and down the tower. "

Humidifier Repair questions, answered by experts

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-home humidifier maintenance needs vary depending on the type of humidifier. Generally, they require regular upkeep. This includes periodic cleaning of the unit, replacing filters or pads, and monitoring water levels to prevent black mold or bacterial growth. The frequency of maintenance tasks may range from monthly to quarterly, depending on the model and usage.

While you’re busy swapping out that old compressor, now is a great time to have your furnace cleaned and serviced , especially if your home is older and your heating system is as old as your AC unit. Likewise, it’s a good idea to clean your air ducts to ensure air flows properly through the house.

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.

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