"They were professional and efficient with the project. My job involved stripping my crabgrass front yard and applying a fresh top soil sod blanket in its place. Gilder is a great communicator and understands how to make the customer happy. I’m planning on using him for seasonal lawn care, based on the performance I’ve seen in this project. I hate giving great reviews because it, usually, means higher prices are around the corner. Trust me. I’m doing this one because I appreciate his work ethic.

"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."

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.
