+ 0 moreJ. J. Sullivan was the only company to offer us the option of replacing only the outside unit and not the interior components (incl. air handler). The more expensive option (which was also reasonably priced) allows a unit with a higher SEER but the increased cost could not be justified by the small increase in efficiency. The new thermostats which we purchased were replaced at no cost except for the new panel. We get our heating oil from J. J. Sullivan and they offer a $0.10 per gallon discount for prompt payment.
Description of Work: Replaced central air unit, interior panel, and two thermostats.

Description of Work: when I told them my tank was on empty I did not feel they believed me. One of their techs came out on day 3 and proceeded to check the gauge which has always been accurate. I will say he did have 10 gallons of "emergency" oil in his van and put in in the tank. Last year the same situation happened and after calling 3 times and 5 days later they made a delivery. |Their oil was $4.15 in March and $3.79 in April. I found oil for $3.49 in April. 30 cents is quite a bit of cash when filling a 200 gallon tank!

Description of Work: We purchased and had installed a Peterson Vented G46 gas log set. JJ Sullivan's price was very competitive with other dealers we solicited bids from and there was no surprise fees or add-ons, what they quoted is what we received. The price included the unit, installation, permits, tank rental, 96#'s of propane and the, ever present, taxes. John P. Sullivan and his staff were prompt, neat and very professional. They eagerly answered all our questions through the entire process and beyond. I would recommend them to anyone!

Description of Work: JJ Sullivan supplies our oil for heating as well as a large propane tank for cooking and standby generator. They are always prompt and courteous. They have maintained and repaired our boiler/furnace. They come promptly when called and i have never ever had a problem with them. One day i thought i spelled gas and I called them and they were there within 10 minutes to inspect. Nothing was amiss but i appreciated their very prompt response.

+ 1 moreThey are of the three different companies that we interviewed and questioned them what their recommendations were what their specifics were. They were the most user friendly. They were really great with explaining differences and kinds of systems and what we could expect from xyz and gave us good alternative. They did a great job. I would continue to use them.
Description of Work: I used J J Sullivan Heating. They replaced our entire HVAC for the house we bought. We also bought heat pump from them and they did all the installation and setup. We also taken them as our propane service provider.
