"Climate Mechanics worked hard to make sure we had both systems replaced on the same day and before the summer heat started. Nathan provided excellent service and communication throughout the whole process, from the first visit through the install. We are very happy with our systems and are confident knowing we are working with a local company that will be there for the service and maintenance of the units."

"My wall gas heater one day just went out. I called several companies and was told they didn’t service that type of heater. One company gave me the number for Angi. The guys with Whitestone came immediately and suggested I replace it because the problem was the pilot. I bought a new heater and they installed it in just a couple of days later. I feel that they were very knowledgeable, diligent and pleasant. It’s working great."

Customers say: Quality work

"Excellent plumbing company. Knowledgeable, fair priced and honest. They installed a new heater in basically one day and it is working well. They disposed of the old heater and everything is cleaned up. Also, easy to work with, did not try to upsell me anything, actually advised me that I didn't need as big a heater as I initially thought. I am very pleased with their work and will use again. Highly Recommend !"

"Lenny and his crew installed a new Lennox furnace for us. The team is courteous and professional. Lenny found that our old humidifier was installed at the wrong place because of the difficult duct work. He went above and beyond his responsibility and installed the new humidifier at the correct position. I greatly appreciate his honesty and utmost professionalism. It is no wonder that his company gets consistently high reviews."

"I had such a great experience with Liv Air! They serviced my boiler, and from start to finish the process was seamless. Leo is incredibly professional, easy to speak with, and genuinely such a nice person. He?s honest, reliable, and you can tell he truly cares about his customers. The technician who came to replace the parts was also wonderful ? very clean, respectful, and efficient. I?ve dealt with other companies before, but no one even comes close to the level of service Liv Air provides. Their pricing is fair and reasonable, and they answer calls right away, which is so rare these days. I?m honestly taken back by how great they were. I highly recommend Liv Air!"

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"Alliance service pros came to our house to find out why nothing was flowing from our house into my septic tank. They found that the pipe from the house to the tank was failing due improper installation when the house was built. Alliance arrived at our house before the time frame they gave me. They were up front with every charge throughout the process of identifying the source of our problem. A second truck had to be called in with extra equipment and supplies. They did not leave until our problem was solve. This company is honest, reasonable, professional and the guys are very kind. We would highly recommend this company."

Install Boiler questions, answered by experts

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.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.
