"The experience was excellent.  Mike is knowledgeable and professional.  I recommend him highly.  The work was done on time and on budget, even though there was extra work required.  The job site was left spotless and neat.  The work was done in accordance with the highest standards."  Roger, Amherst NH

"A+++ You more than installed my new boiler, you rescued my from the fear of overpaying and needless house calls due to the high pressure "fear tactics" used by the former company I had.  You let me know what and why I needed this boiler, took special care to respect my home's needs and didn't leave me feeling lost when you were done with the installation.  I know I can count on you if the need arises and that is such a comfort!  Thanks for everything!"  Judi, Merrimack NH


To many homeowners, the term "heat pump" is a little confusing. The best way to look at it is that a heat pump is a central air conditioner that can heat your home too. When the temperature is hot outside, a heat pump works just like an air conditioner to cool your home. As the outdise temperature cools down, the heat pump automatically reverses the refrigerant cycle to heat the air in your home.


We can combine a high efficiency gas furnace with a central heat pump to create an energy efficient, dual fuel heating and cooling system.


Whether you are replacing an existing air conditioning system or installing air conditioning for the first time, we have many choices to suit your needs.


"From the start, the project went very smoothly.  Mike came out to look over the current heat and A/C system and explained the newer technologies available.  He took time to answer my questions and had a detailed quote the next day.  The new duct work they installed really helps the system perform and look much better than before.  To me, the little details can make a difference.  For example, the AC tubing and electrical are dressed very professionally, which is often ignored by most contractors.  The few issues I did have were addressed quickly.  Overall I am pleased with CHC and my install experience." Jim, Nashua NH


Small duct heating and cooling systems are a good solution for existing buildings that do not have ductwork or have inadequate ductwork, older homes where the installation of traditional ductwork is not possible. The small 2-3" insulated, flexible duct can be easily routed through existing structures with minimal remodeling.




Several companies, such as Harmon, make pellet-fired furnaces for replacement of, or a supplement to, gas- or oil-fired furnaces in residential space heating systems. 


"Dear Mike, Thank you so much for the fine work you did installing my pellet furnace.  Working with you has been the most satisfying experience I have had with a home contractor for some time.  From the first visit to firing up the newly installed unit, you were a model of honesty, professionalism, and considerations for the job and my overall satisfaction.  I am simply thrilled the way my furnace is working.  Mike, they just dont make many like you.  I am so glad to have found you!  Very best wishes to you and Steve." Charles, Mont Vernon NH


EcoHeat Solutions offers the EcoBoiler and American-made, ASME-certified wood pellet boiler.


"I can not recommend your business enough.  The process of installing my pellet boiler was painless and your team was more than responsive with every question I had.  Even with the requirements of the NH Rebate you helped me every step of the way.  With the hiccups of having an older home you were there to correct and figure out every issue I had.  This is by far the best experience I have had with any contractor who has worked on my home.  The final product looks great and works awesome.  Great people to work with and the price was right where I had hoped it would be."  Matthew S, Amherst NH

"Thank you to Mike and his entire staff for an exceptional job on our air conditioning!  We are so happy with it.  We truly appreciated the professionalism everyone demonstrated during the entire process.  We will definitely recommend you to others!!  Thank you again!!


Michelle & Tim Redfern

"Exceptional service and value!  The work was delivered at less than half the cost of other estimate.  But the work is first-rate and Mike took the time to make sure I was happy with the work and my questions were answered.  Lastly, he found an issue unrelated to the work he was contracted for and simply just fixed it.  I highly recommend Card Heating and Cooling."
