"Tuesday night at around 5:20 pm I realized that my furnace was not working. Always a scary thought on a cold winter's night. I had never worked with Joyce, but ironically I had a regular maintenance/inspection scheduled for my furnace in a week and a half. So I called and left a message saying I had no heat. I was fully anticipating that I would not be given priority since I was not yet a customer and most likely there would be a lot of customers who had emergencies like mine. Joyce opens at 7:30 am. At 7:15 am I received a call that they could send someone out that morning much to my surprise. My furnace was repaired by 10 am that day and at a reasonable price! Alex, the gentleman who repaired the furnace, was polite and professional as was the woman I dealt with in the office. I will most likely be signing up for their maintenance plan."

Customers say: Quick response

"We had a leaking 35 year old oil-fired boiler that needed to be replaced. This was just at the start of the heating season in 2021. We got quotes for price & installation dates from several HVAC companies Clear All HVAC supplied several boiler replacement options and also quoted an earlier delivery date than any other quote. We selected a boiler/indirect water heater combination that was significantly less than competing quotes. Clear All installed the system within a week and responded quickly to any concerns & questions we had. We highly recommend Clear All HVAC for anyone that needs HVAC installations, repairs, service and values good customer service. In our opinion they are outstanding and we will continue to use them as our go to HVAC Services company."

"I would highly recommend Druziako HVAC Co. to anyone needing repairs and or replacement for Heating and cooling service. We lost our furnace Heating in the middle of the cold snap, these guys came out and immediately found the replacement system we needed and promptly replaced the next business day. Job completed, who does that..? The owner even called us during the night and offered to bring us a temp heat source if we needed it. Fortunately we did not. We can't say enough about the service. I would use them again and plan to for future cleaning and service. Nick ( the Owner i guess) and his guys did a great and professional job. Thank You Nick...!"

"We have a heating service contract with Sila and had our annual scheduled service call on 2/26/19. We've always had excellent experiences with the staff who have serviced our furnace, and today was no exception. The technician, Guy, came promptly and very efficiently performed the required testing and measurements of the service procedure. Before he left, I asked for some information about future replacement of the burner and possible changes to our heating zone arrangement. He gave a very clear explanation of what to consider about making any future changes, what might potentially be involved, and answered all of our questions knowledgeably. Thanks to him we can proceed with our decision process with better understanding."

"The technician was personable and arrived on time. He answered all of my questions. He even had the office call me the same day with regard to an inquiry about getting a new furnace."

"I called Unique Indoor Comfort to take a look at it at on a Sunday afternoon. They sent Steve M out to take a look at it. He was very friendly and patiently listened to my concerns and answered my questions. He systematically checked various components and found some debris stuck in the pipe connected to the inducer motor. He removed the debris and that seemed to fix the problem and said that this would get me through the night, at the least. As a recommendation, he said it would be best if I replaced a part that is slowly falling apart. He would check with the manufacturer and call me the next day. The cost for the emergency call and check up was $150. Pretty reasonable to me. The next day, Steve M called me and said my furnace only had a 5 year parts warranty, so I would be on the hook for paying for the part. He advised me not to spend the $850 for the part right now, but instead do a complete maintenance and cleanup for $168. I took Steve M's advice. The next day, Steve C (another Steve at the same company) came out to do a complete clean up and check up on my furnace. He found bits of PVC pipe burnt up in the heat exchanger and removed them. Steve C seemed to do a very thorough job. He also took the time to answer my questions I will be using Unique Indoor Comfort in the future to do maintenance check ups. I had used another company a few years prior, but they didn't seem nearly as thorough."

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"Palmer sent two great technicians out- Jason C and Matt D to upgrade our thermostat for a summer home. The arrived early and were exceptionally efficient. They remained on site until the system was satisfactorily tested and I was happy with the work. From the customer service scheduling call to the project itself Palmer provides a great customer experience."

"They were very professional and did a fantastic job. They showed up on time, installed the system in a timely manner, spent extra time unclogging all pipes and faucets from the excess minerals. They arranged for the electrician to add extra plug sockets. They did a great job explaining the system and cleaned up after themselves."

FAQs for furnace / forced air heating system install or replace projects in Nashua, NH

Converting from an oil furnace to an electric furnace isn't a simple swap—the oil system needs to be completely removed before installing the electric furnace. You'll need a full electric system installation, but you might be able to reuse existing ductwork if it's up to current safety standards. You’ll need to budget for a new electric furnace installation, which costs between $1,800 and $6,200, including professional removal, proper disposal, and safe installation of the new system.

Electric furnaces are 100% efficient at converting electricity into heat. However, some of that heat can be lost as it travels through your home's ductwork or escapes through poorly insulated areas. That's why regular duct maintenance and proper home insulation are important to maximize your furnace's efficiency and reduce heat loss, ensuring consistent warmth and lower energy costs.

With proper maintenance, an electric furnace can last anywhere from 20 to 30 years, outlasting the average gas furnace's lifespan of 15 to 20 years. To keep your electric furnace running efficiently, schedule regular cleanings, tighten connections, and have inspections done before winter arrives. With routine maintenance, you’ll ensure consistent, safe heating for years to come.

The size of the electric furnace you need depends on factors like your home's square footage, climate, and insulation quality. As a general guideline, those who live in warmer climates should multiply their square footage by 30 to 35 BTUs, while those in cooler areas should multiply it by 50 to 60 BTUs.

Consulting with an HVAC professional can help you determine the exact size that's right for your home.

An electric furnace works by converting electricity into heat using high-resistance heating elements. A blower then pushes the warm air through your home's ductwork, distributing heat evenly throughout your space. Since there's no combustion involved, electric furnaces eliminate the risks associated with gas furnaces and provide consistent, reliable heating when properly installed.

An electric furnace uses between 40 and 80 kilowatts per day to heat your home. The exact amount it uses depends on factors like your home's size, insulation, and overall energy requirements. Larger homes or those with poor insulation use more energy than smaller, well-insulated spaces. A professional furnace assessment can help confirm the ideal unit size for your needs.
