Another oil to LP conversion, featuring a Lochinvar Noble boiler. Whisper quiet operation and 10% more efficient than the old Peerless boiler we removed.

Another day, another Bosch! We removed....actually the customer removed this oil furnace so we could install a new Bosch 20 SEER heat pump system with electric backup and Honeywell steam humidifier, Trion Air Bear filter for improved filtration. We added a Bosch wifi smart thermostat for wireless control and monitoring from anywhere.

"My oil tanks LOOK fine"
We hear this way to often. These two tanks were 25 years old exactly, which is their actual life expectancy. They had leaked due to pin holes that form from the inside. Condensation forms in tanks and will run down the inside of the tank. These droplets will find spots to settle in the tank. They are then shielding the bare steel from the oil. The water drop causes the tank to form an internal rust spot. The sludge also has a bacterial growth that form that will feed on the hydrocarbons in the oil. Don't wait until you come home to oil on your floor. Glad Camp Spofford keeps an eye on their equipment and caught it before it was worse. We went to a single Roth tank as they swapped out a system to gas already, so less oil is needed. And at these prices, thats a good thing!

Here's a recent commercial swap for Supreme Fitness in Brattleboro, VT. We removed two 15t York units that were 42 years old and barely functional. One made hear still, one made AC still. With the skills of Wilcox Crane Service, LLC, Jake, we placed two new 15t Rheem multi stage systems with Siemens Climatix controls for balancing, fresh air exchange, and air speeds. New ducts were fabricated by hand using 22 gauge coated,sealed aluminum 4×10 sheets. We then covered the ducts in aluminum backed 2" foam sheathing and sealed with aluminum flashing tape. Systems programmed for the space and put into operation. The gym members were much happier to have AC and dry air again.

Hello friends! I know I'm not always easy to get ahold of, and not always quick to respond to some calls. I haven't added an office staff yet. so it's just me. I typically am out in the field early, and back late, so my concern is calling to early, or too late. During the day, its tough tk stop working to be on the phone. We are technically closed on the weekends, and I worry that it would be rude to call back on a Saturday, but sometimes thats my only day.

So I turn to YOU for suggestions. What are the preferences for a return call in my situation?Early am, Late afternoon/early evening, or Saturday morning? Help US improve on helping YOU!

We are closed today for team building

Sometimes our heroes need heroes, and we were happy to answer the call when Keene Fire Dept. called us in a bind. Their emergency portable ac wasn't doing much more than blowing air. So we went down and found it low on charge and lacking a return duct. We got two new insulated ducts to improve efficiency, got charged to specs with some fresh R22, and ready for the July 4th festivities. We hope this tent sees very little emergencies but is nice and comfortable should the need arises.
