"I have been a customer for a very long time and this scheduled maintenance and dryer vent cleaning was done by Cesar. I have to say he is one very thorough technician and I was very pleased with his inspection and vent cleaning. His service was so different than some of the ones I've had before. I even had one inspector tell me he didn't need to check in my attic which houses one of our two units. Let me tell you about Cesar, he even cleaned up behind my dryer for me. This is something that is rare in customer service. I have my HVAC seasonally maintenanced and never had a inspector be as thorough as him. The pictures he took and explained to me and the one problem he found that no other inspector had found in all this time. I tried to spare him from the attic heat for the repair and have him return on another day in the morning but he didn't mind going back in there to fix the problem for us although it was in the dead heat of the day. I just hope the company sees this review and knows what a good technician they have in Cesar."

Unless you're very skilled with HVAC, plumbing, and electrical work, it's best to hire a professional. Improper installation can damage your HVAC system, increase energy bills, and reduce equipment lifespan. A pro will ensure everything is installed correctly and safely.
It depends on your maintenance preferences and budget. Drum humidifiers cost less upfront but require more frequent maintenance to prevent mold growth. Flow-through humidifiers are a bit more expensive but need less upkeep because they have fewer parts that can harbor mold. Consider how much maintenance you're willing to do when choosing between the two.
Repairing a whole-house humidifier costs an average of $230, with prices ranging up to $500 depending on the type of unit, extent of the repair, and labor fees in your area. Units integrated into your ductwork or servicing larger homes may incur higher repair costs. Regular maintenance can help prevent expensive repairs and extend the life of your humidifier, saving you money in the long run.
If your home's humidity level drops below 30%, a whole-house humidifier can help. Dry air can lead to discomfort and health issues. Energy Star recommends keeping indoor humidity between 30% and 50%. In colder regions, aim for 30% to 40% in winter to prevent window condensation. If your home has too much humidity, you may need a whole-house dehumidifier.
Whole-house humidifiers typically last 10 to 15 years. If your unit is nearing this age or isn't working well, it might be time to replace it. Upgrading can improve efficiency and save on energy costs. Consult a professional to assess your unit.
A whole-house humidifier is installed directly into your HVAC system, usually near the furnace or air handler. It connects to your ductwork and plumbing. Because installation involves integrating with existing systems, it's best to hire a professional to ensure everything works safely and efficiently.
