"We had Chris replace a decades-old gas furnace and electric water heater, as well as install central air conditioning. We talked to a few professionals in HVAC, and Chris seemed to have encyclopedic knowledge of it all. At a very fair price, Chris spent two days having the old stuff professionally removed, getting the new stuff (AC) wired up, and all the new equipment installed. This was a problem-free project from start to finish, and we would strongly recommend Chris to anyone with similar needs."

"Not easy finding an HVAC company willing to install a gas steam boiler. These guys did it all and did it well, removing the old oil burner and oil tank, installing a Weil McClain boiler including steam piping and hot water, installing gas piping, electrical and plumbing, including all inspections, even leaving me a temporary hot water heater until the furnace installation was completed. They fully accommodated my schedule as well. The town electrical inspector who came after installation was complete confirmed their good reputation."

"My wife and I recently had our furnace replaced by Rodenhiser Home Services. The initial problem was the igniter on our 22 year old system failed. We called Rodenhiser on Saturday morning, November 14, and although we were not a current customer, they stated they would schedule a technician to come to our home on an emergency basis. The technician was onsite within the hour and confirmed a failed igniter. Since we were going to replace the system anyway due to the AC condenser having failed the year prior, we asked to speak with Rick Picard, the HVAC Specialist. Rick discussed with my wife and I our options and worked with us to get the product we wanted installed as quickly as possible. Rick was extremely helpful throughout the process of describing which systems were available, and assisting with the securing of the MassSave Heat Loan Program. On the day of installation, we were greeted by Tyler Durran (Lead Installation Tech), and Matt (Apprentice Installation Tech). Both fine young men who were polite, courteous, and conscientious of their work. Both Tyler and Matt were professional and exhibited a solid work ethic and displayed genuine pride in their work. We were also greeted by Tim (Lead Electrician) and Alex (Apprentice Electrician) who were to handle the rewiring of our new furnace. Upon inspection of the Service Panel, they found the source connection from our electrical provider to be loose within the service panel and not making proper contact. It was a fire hazard and we were fortunate that the problem was identified. A call was placed to their manager, David Cassidy, who arrived and advised us of our options. We chose to have the entire service panel replaced, and David did an excellent job of dressing the cables and providing a neat service panel. He also took the time to use the current circuit breaker mapping we had to rewire the new breakers. All Rodenhiser personnel were professional and conscientious of their work. We would recommend Rodenhiser to those in need of the services they provide"

Heating and Air Conditioning FAQs, answered by experts

Ceiling fans can be a great way to cool your home without the expensive utility bill of running an air conditioner. Plus, ceiling fans can sometimes run in both directions, pushing hot air down in winter and pulling cold air up in summer. With that said, air conditioning might be the only thing that helps if you live in a very warm climate.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.
