"I scheduled a tune-up service for my AC for 9-12 o'clock. At 11:35, I called to see if they were still coming, and she tells me 'sorry, the tech is running behind. He will be there closer to 1:00'. I accepted that, then waited until after 1:00 to call them again, only to find out the tech was still an hour away, working on another job. I thought the whole point of a service 'window' was to provide flexibility for the tech in case they get held up. I had to leave my house by 2:30, so I canceled the appointment. I took out an entire day for absolutely nothing."

"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)."

Humidifier Repair questions, answered by experts

No, air purifiers neither cause dry air nor increase the home's humidity levels. They remove allergens and dust but don't alter the water content in indoor air. However, because some air purifiers move large volumes of air, the areas immediately surrounding a portable unit can feel cooler and dryer than the rest of the home.

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.

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.

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.

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.
