"job was done in a timely manner, however was not done in a professional workman like manner, Which the contract states it would be done. When the estimator came he explained what would be done to eliminate water issue. When we asked how does water get removed outside and how they would undermine stairs and walls he simple stated the installers will go over that with you when they come. The installers said they would be channeling under the step and walls, which are only 2 1/2 inch walls. The last step was also a simple channel as well. More time consuming perhaps, when you charge $3000.00 more than another contractor, homeowners are believing they are getting a professional job! They cut her stair runner instead of peeling it back so it could be glued back down. she needs replace whole runner now and company could care less including there estimator! sheetrock replacement also more expensive because took a hammer to the walls instead of saw zall,nice straight lines! also have photos."

"I AM LIVID WITH THEIR SERVICE. My husband and I have been living in our home 4 years without a single issue with our cooling system. We had UGI come out to "service" our system and said everything looked great....2 months later something with our compressor blew...that was $400. Then this morning, less than 30 days later, we apparently needed a brand new thermostat.....another $400 and guess what? MY HOUSE IS STILL NOT COOLING DOWN. So I called and said how it is absolutely ridiculous that there is still an issue especially after charging us to "fix" the thermostat. I am obviously frustrated. I work from home, its hot and I am pregnant with 4 pets in my home that are distressed from the rising heat and their customer service agent has the audacity to be BEYOND RUDE and tell me "to have a better day" as if it was MY FAULT...ok. It is very odd that ever since they came to "service" our central air system they've had to come back THREE TIMES and the system STILL NOT WORK. BEWARE!"

Air Duct Cleaning questions, answered by experts

You might have heard that closing vents in unused rooms can help with energy efficiency, but it’s never a good idea to block air vents completely. Fully closing vents can create a buildup of pressure inside your ducts, which can lead to leaks, holes, or other problems. Instead, you can shut your vents partially (between 50% and 75%) in unoccupied parts of your home.

Several factors contribute to the persistent growth of mold in vents, with excess moisture being the most common culprit. Consistent mold formation in vents indicates an ongoing moisture problem within the HVAC system or its surroundings, likely caused by condensation on cool surfaces in areas with high humidity. Moisture accumulation can also result from leaks in ductwork, inadequate ventilation, or insufficient insulation, creating an environment favorable for mold growth. Regular inspections, addressing potential sources of moisture, maintaining proper ventilation, and routine HVAC maintenance can help prevent the recurrence of mold in vents. If the issue persists, seek professional assistance to identify and rectify the underlying problems.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

HVAC maintenance is crucial for the longevity of your unit. Without proper care, your HVAC unit can break down frequently. In addition, a system that is dirty and not cleaned correctly will not heat or cool as efficiently and will increase your energy bills due to the increase in energy consumption. Additionally, you will probably have to replace your unit sooner than you would if it were properly maintained, which will cost you more money. 

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.
