Family-owned and operated propane and fuel oil delivery and service company with a 90-year history serving New Hampshire, Northern MA and Southern ME. Our friendly, simple and safe fuel delivery and service programs keep our customers warm in the winter and cool in the summer. Automatic delivery, easy billing, and maintenance plans make it easy to keep your tank full and your equipment in tip-top shape. A one-stop shop, in addition to fuel we also offer equipment sales and service, installation, and electrician services. Best of all, we show up to work every day with a SMILE on our face! Giving to the community is also very important to us. We support local Fire and Police Departments, libraries, youth leagues and fraternal organizations from various towns.

"We recently switched our provider of propane to Palmer Gas & Oil and have been extremely happy with the process. Both Michelle and Kim were great on the phone, setting up our account, determining our needs, scheduling our installation and answering our questions. During our site survey it was clear that Michelle was quite experienced and made the next steps easy. The removal of our old tanks and installation of new ones went just as planned. Rick R and Nate arrived right on time and greeted us with a smile. After checking all of our gas operated appliances to be sure they worked properly, we sat down and talked with Rick about safety. While we’ve had propane for a number of years we weren’t aware of several things that he told us about. We just purchased a gas detector, something we hadn’t heard of before. It’s a great feeling to know that we made the right choice switching to Palmer and look forward to a long and pleasant relationship with the company."

Heating and air conditioning services FAQs

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
