"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

Mold in air ducts releases spores into the air, which cause allergic reactions and respiratory issues. Common symptoms include coughing, sneezing, or itchy eyes. Prolonged mold exposure can lead to more serious health issues, especially for those with compromised immune systems.

Ductwork should be thoroughly cleaned at least every three to five years. An air duct cleaning specialist will need to clean and inspect the ductwork for any leaks or other damage. You can also help keep the air ducts clean by changing out air filters every 30 to 90 days.

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.

Ductwork will occasionally make noise as the metal experiences rapid temperature or air pressure changes. This is especially common when the furnace initially kicks on and pushes warm air into cold air ducts. However, this noise should not occur if the home is at a normal temperature most of the time. If you are hearing noises regularly, it may be a sign of a more serious problem.

While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.
