"I had Premium Home Services install a new oil heat furnace and I couldn’t be happier with the result. I am a new resident here and discovered that the old furnace had rusted and was leaking fumes. They came right out and did an inspection and then made recommendations. Since I am a senior on a fixed income, I was happy that there were many options and that I was able to chose something affordable. From the ease of financing, throughout the installation and final visit, I interacted with quite a few folks at this company and everyone of them were pleasant and professional. I highly recommend this company and their stellar service! Thanks Premium, you all gave this old gal a much needed good experience!"

"My airhandler unit in the attic rusted thru and was leaking water requiring a replacement the whole heat pump system (25 yrs old). The replacement took three days to finish due, in part, to the unexpected addition of three new ceiling vents for proper airflow, getting the necessary parts, and fabricating the associated duct work. I was impressed by the dedication shown by the installers to insure that the system was installed properly and also integrated correctly with my hot water boiler heating system. Additionally, Jennifer at McCarthy followed up on getting me a Carrier rebate for my system. My system has been in place for 5 months now and no installation or equipment issues. My thanks to the McCarthy team."

"What a wonderful company! From the first call returned at 10 pm the night our furnace died to the final touches of installing the units (we opted to replace our 20 year old furnace and water heater), Matt Conde and his team were efficient, professional and knowledgeable. They made a much appreciated effort to explain our problem and the most cost efficient way to deal with it. Never did we feel pressured to make a purchase but we did feel confident that all possibilities were explained. They even installed a temporary part so we would have heat while the new unit was sent from Kentucky. I plan on signing a maintenance plan for spring and fall HVAC check ups!!!!!"

"The pros at Local Heating and AC saved our Christmas! My gas furnace went out at 11 am on Christmas Eve when it was 15 Degrees outside. I called them in a panic and they were there withing 90 minutes. I have a very old gas furnace and the part that needed to be replaced had to be ordered but they figured out a way to keep my furnace going until the part came in. I am not exaggerating when I say that they rescued us when many would have just left without finding a temporary fix. I would recommend them highly above the major companies in this field who didn't answer their phones or said that they would be there in 5 days!"

"We just purchased our home that had a new hvac system installed. But once we moved in we struggled with keeping warm & were using space heaters in addition to the heating system. We had several estimates. ARS sent Matthew to check out our system & why it was not working properly, who was amazing & very professional. He gave us a clear & understandable explanation why it was not working properly & our options for the system. We opted to have a Comfort Care coordinator, Brandon, come out to give us different options for repair & replacement. We opted to replace the whole system because there were some major issues that really needed to be addressed & fixed. When the installers arrived, there was some misunderstandings & miscommunications & both Matthew & Brandon went above to help clear those up immediately!! So far we are so please, not only with our HVAC choice, the company, & the care we were given by both Matthew & Brandon!! We definitely recommend them for your HVAC needs!!"

Frequently Asked Questions
What is a furnace?
+
What is a furnace?
A furnace generates and distributes heated air throughout your home. A vital part of the heating, ventilation, and air conditioning (HVAC) system—though it does not cool air—you activate a furnace when you set or adjust the temperature in a room using the thermostat. Furnaces can run off natural gas, oil, electric, or propane.
How long does a furnace last?
+
How long does a furnace last?
The average gas furnace lasts 15 to 20 years, though some electric furnaces can last 30 years or more.
- Gas furnace: 15–20 years
- Electric furnace: 20–30 years
- Oil furnace: 15–20 years
In addition to furnace type, your unit’s lifespan also depends on its size and the heating system you have—two-stage furnaces are more efficient and less likely to break than single-stage furnaces.
Having a reputable HVAC technician perform annual furnace maintenance and inspections can help ensure you get the most out of your unit. And, as always, change your filters regularly—a dirty filter can block airflow and overwork the motor.
How often should you change your furnace filter?
+
How often should you change your furnace filter?
You should change your furnace filter every one to three months to help maintain air quality, keep energy costs in check, and extend your unit’s lifespan. If people in your home have dust or pet dander allergies, you may consider changing your filters more regularly. Looking for an even simpler guideline? If the filter is dirty, replace it.
How much does a new furnace cost?
+
How much does a new furnace cost?
The average cost of a furnace unit is $2,300 to $7,200, plus $150 to $500 per hour for installation. Furnace replacement prices depend on the type of furnace you need, its size, and local labor costs.
- Gas: $3,800–$10,000
- Electric: $2,000–$7,000
- Oil: $6,750–$10,000
- Mini-Split: $2,000–$15,000
- Geothermal: $4,000–$17,000
If your furnace installation requires new gas lines or additional ductwork, add $250 to $800 for the gas lines and $3,00 to $5000 on average for the ductwork to your overall project costs.
