"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 gas boiler stopped working. I wanted to find a local contractor and came across Whitestone Heating and Cooling. After some research I read their reviews which were all excellent. So I called and Oscar came to my home. He and his partner looked at it and thought the leak was caused by a problen that renders the heater unrepairable. After relighting the pilot light he made a slight adjustment to the valve which stopped the leak. He could have just told me the heater was cracked and useless just to have me buy a new one to make himself more money but he didn't which i was so very grateful. He's coming back to put a sleeve in the chimney. I recommend Oscar and Whitestone Heating and Cooling to anybody who needs help with their heating or cooling systems. Today its so hard to find a contractor who above all is honest and wont take a person to the cleaners. Rest assured you can trust this one. Thank you again, Oscar. God Bless."

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."

"My house has been sold. One of the things on the inspection list was clean the furnace. Chris Jr. did open the front & showed me that the inside was still very clean but I told him to clean anyway. Then he found a little water on the floor next to the furnace & discovered a leaky pipe. Explained everything he was going to do & gave me an approximate cost. He was efficient & professional. Had an excellent experience with this company. I intend to recommend them to others."

"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"

"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!"

"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 FAQs, answered by experts

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
