"First the owner of NPM Heating and Cooling (Andrew) came by and spent nearly two hours in my home doing a thorough inspection of the furnace for carbon monoxide leaks, etc. He ran the furnace for awhile and checked all areas of the home with a hand-held carbon monoxide detector as well as other tests on the furnace itself. He found 0% evidence of carbon monoxide and the furnace was functional when he left. However, since my home had no carbon monoxide detectors installed, Andrew cautioned me to make sure and install some before using the furnace.
A week or so later after I had installed the detectors, the furnace began to make a loud noise. So I called Andrew back and after our conversation he felt there was a good chance that the blower motor was going out. Since I know I'll be replacing the entire HVAC system within the year, I hated investing much into the old furnace, but needed to buy time.
Within a week, one of the NPM technicians was here and completed the repair with a used blower motor at less than half the cost of a new one. He was also in my home for nearly two hours and the total cost for all this service was $190.
The furnace and AC in my home are so old (installed in 1988) that I'm actually fortunate that they have lasted this long. I do plan to have the entire HVAC systems replaced within the year, and NPM will do that job. The efficient and reasonably priced repairs were a godsend, as I needed some time right now to gather up the funds to invest in replacing the HVAC systems.
Very professional and knowledgeable. I especially appreciate their honesty. They told me the truth after other contractors did not. A+
NPM is VERY highly recommended!

"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

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

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.
