"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 Oil questions, answered by experts

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.
