"Great Experience. I was concerned about the 22 yr age of our air conditioner able to keep working and wonder if a long wait time to get a product shipped like refrigerators last year, I called for a quote and within a week it was installed and working! Installers worked tirelessly until their work was done, clean and neat!"

"I cannot say enough wonderful things about this amazing company! My daughter and I had been without a furnace for over 6 years. We used space heaters in the bedrooms, bathroom and kitchen, but the rest of the house stayed cold. Along with that, I had a constant fear of an electrical fire resulting from the units, because last year a young mother and her baby died in a house fire down the street from us, most likely caused from a space heater. When Schraer came to our home that offered to install gas furnace free off charge that was just sitting in their shop! We are truly Blessed and Grateful for their kindness and generosity! There are good people out there in the world, and the owners and employees of Schraer Heating and Cooling are some of best!"

"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!

Install Boiler FAQs, answered by experts

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

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. 

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

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.
