"A couple of years ago this company installed my tankless water heater
and I really liked the owners Andy's professionalism. We were having
problems with the water heater and Andy sent some of his workers out to
fix the problem right away.
I referred this company to a friend of mine because of the great experience I had, she used them and they were even able to do a couple of other things around her house that was in the scope of their work.

"Last December, on one Friday early evening, I noticed my heating system was not working and it was very cold. I called PHCS services and they sent a technician Saturday morning to diagnose the issue. FYI, I am a handyman and fix a lot of things around my house, but I don't have the right tools for this service and don't like to do anything with gas pipes. I watched the technician doing his work and realized he is an expert. He checked everything and was able to detect that the gas valve was the culprit. He also recommended replacing the pressure switch. He explained to me what was happening and even showed me how the failure was triggered. In addition, he checked the whole system and even recommended me to install two carbon monoxide detectors, one by the heating system and one on the first floor by the bedrooms. I haven't bought and installed them yet - mea culpa. He didn't have the parts in his truck, but he said, Monday morning another technician would come with the parts and replace them. Before leaving, he explained to me that I could turn on the heating system for a few minutes to heat the house until the pressure valve would fail. After that, I would need to wait sometime and then could turn on the system again. I followed his instructions and was able to stay and sleep in a warm house on Saturday and Sunday. As promised, Monday morning, another technician came over, replaced the parts, and made the necessary calibrations. Few days later, I received an email with the bill, which was very reasonable, and so far my heating system is working like a champ. It is nice to know that there are still good and honest people in this world."

Install Boiler FAQs, answered by experts

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water.
