"I began the project on Angi to switch out 2 old bathroom faucets for new ones. I explained the scope of the project in my angi query but also individually to Jose, owner of Santos construction, once he reached out. He provided me a fair price of 300 and we agreed to schedule the work for Monday, October 27. On that date, he was hours late and arrived around 8pm. I had the new faucets, and supply line kits set out for him and he got to work. The installation of the new faucets took about 2-3 hours. I paid him via personal check for the agreed amount and he left. He left quite a mess in the bathroom, a trash can full of water, and used 2 entire rolls of toilet paper to soak up some mess which were also left aside for me to pick up. It wasn't a huge deal but I wish he would have communicated the need for towels, paper towels or that he'd left a mess. The next day, Tuesday, I texted him at 7:30am because one of the faucets was dripping heavily and consistently all night long. He responded that he would return on Saturday. Saturday came and Jose said he was held up and could not come to fix the dripping faucet but could come Monday. I was growing irritated with the week of a leaking faucet and concerned about the wasted water and expense but we scheduled his return for monday evening. Monday evening Jose texted that he could not come. I suggested the next day and he said he couldn't return until Thursday. I expressed my concerns about my water bill and how delaying the correction of the issue was a problem. He committed to coming Thursday and said he wasn't sure why is was leaking because the valves were closed. On Tuesday morning, we realized that the other sink had been leaking profusely underneath, into the cabinet. Many toiletries and small appliances had sat in water for a week and were ruined. I immediately contacted Jose and asked him to return to fix both of his installations that day. I said I couldn't wait until Thursday with this major leak. He said he couldn't come but would come Thursday or try for Wednesday night. I contacted a plumber because I was concerned about the water leaking into rhe cabinet, and potentially the floor beneath them. The plumber found that one faucet had a peice of plastic and Styrofoam in it which caused the dripping and the other faucet had a valve left loose and open causing the major leak and subsequent damage. The cost of the plumber to fix the major errors by Santos Construction was $379.00! I contacted Jose and sent him the invoice from the plumber. I asked him to refund me what I paid to him so that I could apply it to the cost to fix his work. He refused and said there was no reason to contact a plumber since he was going to come back in the next day or so. I explained that he wa scheduled to return 3 times and the issues were worsening, and that I couldn't let water keep leaking into the cabinet, floor, and ceiling below while hoping he comes back. I would like Jose to refund me the $300 I paid him so that I can apply that to the $379.00 cost of the plumber to correct his apprentice or novice level errors. Both of the leaks, damage to our things and extra costs to plumber, were completely preventable had he not been negligent the night he installed them."

Heating and Air Conditioning questions, answered by experts

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

No, a furnace is not the same thing as an AC, or air conditioner, but these are both parts of an HVAC system. They both use air ducts to transport cool or hot air around your home to achieve a comfortable temperature set by your thermostat. An AC runs on electricity, while a furnace can use different fuel sources.

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

The first sign you're not getting enough return air is if some parts of your home feel hotter or colder than others. If nothing else is causing that, leaky air ducts are your next clue. If the air pressure feels different in every room, this is also usually a sign of insufficient return air.
