"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

"This review is long overdue! We had the pleasure of working with Robert on renovating our new house from top to bottom almost a year ago, and we are still thrilled with the results. Their professionalism, attention to detail, and commitment to quality has created a deep trust in Robert. He is top of our list and we have recommended him and his team to all our family and friends. We knew he would be a good fit from the initial consultation. Roberto managed everything with care and great attention to detail. Robert and his team executed our vision so well and everyone who has been over have showered us with compliments at how good everything looks. Throughout the renovation Roberto maintained excellent communication, keeping us updated at every stage. They were always punctual, courteous, and willing to answer any questions we had. His team was respectful of our home and ensured that the worksite was clean and organized at the end of each day. The quality of workmanship has proven to be outstanding and the custom work will last us for years to come. Another impressive aspect of working with Roberto and team was their ability to stay on schedule and within budget. They provided a clear timeline at the beginning of the project and adhered to it, completing the work on time without any unexpected costs. Even after the project was completed, Roberto continued to provide exceptional customer service and followed up to ensure we were satisfied with the work. We highly recommend Roberto to anyone looking for a reliable, skilled, and professional contractor. Our new house is beautiful and suits us perfectly thanks to Roberto and his team!"

Boiler Repair questions, answered by experts

There are a couple of signs that will tell you it’s time to bleed the radiator. If the radiator is making noises, it’s typically because of trapped air, which you can release by bleeding the radiator. You can also test the radiator by turning on your heat and then placing your hand near the top and bottom of the radiator. If you feel cold spots, particularly at the top of the radiator, it’s time to bleed it.

Addressing banging, clanging, and hissing radiators involves several steps. Start by bleeding the radiator to release trapped air, a common source of noise. Next, ensure all valves, brackets, and pipes are securely tightened to prevent the components from rattling. You can also consider installing radiator insulation to dampen heat expansion sounds. If you perform all of these fixes and the noise persists, explore the use of radiator additives that can mitigate water-related noises. If all else fails, you should consult an HVAC professional.

Fixing a radiator is worth it because it costs less than fully replacing it. Sometimes, a little troubleshooting can go a long way. The issue could be as simple as a blown fuse, a malfunctioning thermostat, or a loose valve. Plus, your daily life wouldn’t be too comfortable without a functioning radiator.

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.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.
