"initially ok though while onsite I had to ask "what is that rattling noise"...I don't understand how they didn't realize they had dropped a piece of cut duct sheeting into the unit interior. They used bad taping on the modifications they made to the ducts and it all blew apart. called to have them back to fix several times and they never bothered to answer"

"Called Seigmans Forced Air and explained that my regular HVAC company would not return my calls and my A/C was now down for three days. Seigman's sent a technician (Chris) within 4 hours. He diagnosed the problem and found that the fan motor in the condenser was bad. They had to order a new one and it arrived two days later. As soon as it arrived at Siegmans the service manager brought it to our house, as Chris was already here disassembling the condenser so the fan motor could be installed. Siegmans was responsive, professional and solved our problem quickly. They were also able to replace the fan motor and a capacitor under the manufacturer's warranty. I highly recommend this company."

"My chest freezer broke down and I did not want to buy a new one since I could not afford the same size. I reached out to appliance parts pro and they were confident that what I ordered would fix my problem. $200 in parts later and I now have a broken freezer on my porch and am still paying the loan to this terrible company.

"BEWARE, avoid this company at all costs. Scam artist extraordinaire. We contracted Nate Monyer in November of 2021 to install a Generac whole house generator. We were told by him that he had a unit in stock and could have it installed late February of 2022. Although I felt his price was high, I agreed because he had it in stock. I gave him a deposit in excess of $6,000 with the balance to be paid when completed. February got a call, delayed until March. April then May avoids emails calls, finally I was told that the Generator was not being delivered to them because of supply shortages. But wait, YOU said it was in stock. I requested a refund. They would send a refund but keep $500 for restocking fees! When I questioned what they were restocking, he changed his story to “it is for administrative fees”. Then he told me he would take the generator off his show room floor to install late June. That story then changed to he had one from another customer who wasn’t in a hurry and I could have his (yeah right another poor guy who won’t get his on time). Nate just kept fabricating excuses and apparently got lost in his own tales. Bottom line I finally gave up and did receive a refund minus $500. He took advantage of an elderly couple. Be smarter than I was, bad karma here."

Heating and Air Conditioning questions, answered by experts

If your AC refrigerant is low, you may notice that the unit takes longer than usual to cool your home or that your energy bills are higher. You may even feel a warm breeze coming from the vents when the AC refrigerant is low. Don’t attempt to check refrigerant levels yourself. Only certified AC repair pros should check and refill refrigerant.

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
