"It was an excellent experience! My old Kenmore fridge (probably from the 90s) quit cooling/defrosting. After looking to replace it and finding thanks to the pandemic refrigerators are on backorder for months, I called 3 appliance repair companies who didn't call me back. I found Neli and was able to set up an appointment at a time I picked.. An incredibly patient tech (Chris C.) came chat on at the appointed time. I waited about 5 mins as he was wrapping up another call. I walked me through the diagnosis using a virtual support app on my phone. He was able to help me with taking things apart, helped me use our multimeter, and diagnosed the problem. I can do this repair myself. He gave me the exact part numbers and told me what I need to do. All for $35 for an hour on a Sunday. I can't believe how great this was. I thought I had to replace my refrigerator, but for $35 + $111 in parts (I could have gone cheaper but chose OEM) my refrigerator will return to health. Their website lists the tools you will need for a diagnosis/repair, make sure you have them ready. For refrigerators, you need a screwdriver (flat & phillips), a socket set, a multimeter, and theoretically a pair of pliers but I didn't use them. Also make sure your phone is charged (lesson learned)."

"Both the estimator Kevin the two installers who visited my home were very professional and kind.

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.

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.

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

For certain repairs, a plumber may be able to help fix a humidifier, but HVAC technicians are typically the go-to professionals. The most common humidifier repairs that plumbers handle are humidifier water shutoffs, solenoid valve maintenance, and evaporator pad replacement.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
