"I've used Wesson Energy for a few years now as a member of the Connecticut Energy Cooperative. The prices are great and the service is responsive and professional.
In September, I noticed that the gauge on my heating oil tank showed that I was a quarter of a tank low. A few days later I received a notice of delivery from Wesson billing me for approximately 175 gallons of oil (about half a tank). I called to ask why, if I was only a quarter of a tank down, I would have needed so much oil.
Wesson sent out a technician to look at the problem. As it turned out, the gauge was wrong (they acquire a later of silt over time that weighs down the floater). Apparently l had looked at the gauge just after the delivery and the tank wasn't registering as full. 
Throughout the course of several phone calls to resolve this problem, representatives for Wesson were courteous and professional. 
P.S. Wesson definitely fixed the problem; the old gauge remained on the tank so I was able to compare the readings on the new and old gauges. The old gauge consistently registers a quarter-tank lower.

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"We had a Burnham boiler that developed a crack (apparently they are notorious for doing so). It was spewing water all over our basement every time it turned on. Mike came over promptly and assessed the situation, giving us several options. We could have gone with a less expensive boiler, but chose a higher efficiency one as well as a new hot water tank (since ours was about 14 years old) and new connections. The installation took all day and into the evening with Mike and his partner working virtually non-stop. He also vacuumed up five gallons of water from our basement. We felt Mike was very professional as well as pleasant and honest to deal with. The new furnace has been in for a few days and is very quiet. He has estimated a savings of about $900 a year in oil costs with the new system.

"The technician who came was a pleasant, competent professional who examined the unfinished attic to evaluateit w/r/t insulation only or insulation as part of a full finishing of the space. He took measurements and scratched out some information on his pad.. I told him that I intended to review my options before any decision. I offered payment at that time and he told me there was no charge for this service. It struck me as odd that he told me that what I had agreed to pay $19.00 for was actually free but I asumed billing would accompany an actual report/proposal. A month on I've never seen anything like a report although I have been charged via credit card for the inspection service. Perhaps the report-recommendation is still on its way? PLEASE NOTE THAT THIS REVIEW FORM REQUIRES A YES/NO HIRE AGAIN RESPONSE. I WOULD HAVE PREFERRED TO ANSWER UNDECIDED."

Boiler Repair questions, answered by experts

In general, it’s a good idea to bleed air from your heaters at the start of every cold season, before you move your boiler system back into active mode. Early fall is a common time for this task. However, some heating systems don’t need much manual bleeding because of automatic bleed vents and other components.

The average cost for HVAC repairs is approximately $350. However, prices can range from as low as $100 to as high as $3,000 or more, depending on the type of repair and the extent of the damage. For example, a relatively inexpensive capacitor replacement may cost $100 to $500, while a major compressor repair can range from $750 to $2,000. Other common repairs and their typical costs include:

  • Blower motor repair: $200–$500

  • Circuit board repairs: $100–$600

  • Evaporator or condenser coil repair: $400–$1,500

  • Heat exchanger repair: $100–$200

  • Thermostat repair: $175

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

Regular maintenance includes annual inspections, filter changes, and checking for leaks or pressure inconsistencies to improve efficiency and longevity.
