"This place is a scam- DO NOT TRUST THEM! Just pay the extra and work with a BBB accredited company. We are extremely dissatisfied with the service we received today. We hired someone to save us time during a large demo project, but wish we just did it ourselves from the beginning to save time and headache. Based on the company's assessment, we were informed that our dryer vent had a significant blockage, so severe that it would require tearing out walls or possibly going through our new roof. We were obviously concerned about the potential cost and disruption. But don't worry, they're a construction company too... a little too convenient However, after the technician left, my husband decided to inspect it himself since we just had it cleaned within a year ago. Within an hr, he was able to clean out a considerable amount of lint, but there was no actual blockage obstructing the vent. In fact, as you can see in the attached photograph, a standard dryer vent cleaning tool could pass straight through the hose from the front to the back. Not to mention, there is plenty of air coming through the vent and none coming back into the home."

"Thank you to Julio Valle from John Padilla Plumbing, Inc. After I had a lukewarm shower, I called Padilla Plumbing based on their 5 star reviews on various platforms. They had an opening the next afternoon. The gentleman on the phone gave me an estimate for replacing the water heater if that was necessary & told me their service charge would go toward any repair that they did for me. The next day, a gentleman called to say the plumber was running late & would miss the time window. What would I like to do? I opted to have the plumber come the same day if he could do it in the daylight. Julio arrived about 20 minutes later! Yay!! Julio was very professional & courteous. He tested the in-house faucets (upstairs & down) for water temperature. Then we went down to the water heater in the garage. He adjusted the temp on one of the heating elements as it was much lower than the other one. Again, he tested water temps upstairs & the water was already warmer!! This seems to be a well-run, responsive plumbing company that I will call again when needed. Highly recommend."

Boiler Repair questions, answered by experts

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

Each has its pros and cons, but hydronic heaters typically cost less to use than electric heaters, and they’re slightly more efficient than electric options. On the other hand, a hydronic heater usually takes a bit longer to heat up a room than an electric heater. The “better” choice depends on your needs and budget.

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. 

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.
