"My central heating system wasn't working and the previous company that installed my ac system did a poor job. Josh and Eric came and corrected the wiring.

"Updated 4/25/2025 review: would be delighted to change this back to 5 star, but no way at this time. 1 reply since 4/14. No followup; can't coordinate with roofer to actually install A/C unit to my home (each says they will, but neither does), months after it was craned to the roof. Only half the house has A/C, and the single unit working cannot cool the whole thing below 76°. Horrible in 80+° heat. Need relief, and very much not getting it here. Very unprofessional and unethical."

Humidifier Repair questions, answered by experts

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.

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.

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.

The average whole-house humidifier might last 10-15 years. Regular maintenance can help the unit last longer. Keep in mind that houses in dry climates use humidifiers more frequently, which may exacerbate wear and tear. A professional can help you determine if it’s time for a replacement. 

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.
