"This guy is a real pro! The original installer came out and gave up on the problem, and I never heard from them again. Duke came out, and diagnosed the issue in an hour. He even submitted the request for a part under warranty, received it, and came back to install it 2 days later. The cost was very reasonable. Thanks Duke!"

"I hired Comfort Energy to replace my moms heater after reading excellent reviews. The reviews were spot on! Eddie, the customer rep, and Nima, the installer was knowledgeable, straightforward forward and professional. Nima did an excellent installation, followed Covid protocols, and did clean up afterwards. We could not be happier!"

"Understandably and as expected all HVAC contractors were on high demand and all booked up for several days out, so no one in the area was available until the following week at the earliest. We called Mr. Diego Utor and lime everyone else he was also all booked up; however, he added us to his already full day and said he would do his best to stop over. Diego kept his word and arrived late afternoon that very same day. He quickly diagnosed the problem, which turned out to be a bad capacitor. He replaced the part and also checked the refrigerant level for us. Diego Utor is responsive, courteous, honest and his rates are very reasonable for his services. I would highly recommend HVAC Utor Services to anyone for all of their heating and air conditioning needs, whether it's repairs, routine maintenance, or new service installations."

"Pann was knowledgable, responsive, did all work correctly, on time, and within budget. He went above and beyond by taking care of issues he uncovered that we were not aware were there. He worked with us to come up with the idea of installing an Internet closet that made it possible to have less visible cables and cords running on our walls. The finished project works great and I appreciate having a clean look behind my TV stand. Running the new electric to the detached garage was hard work. Pann crawled around under our house to pull the new wiring through. He even worked within our tight schedule of 2 weeks! Again, everything works great and we will definitely hire again for future needs."

"Great! Tony called in advance & was very prompt. Personable and professional, he quickly hooked up his equipment and let the machines do their work, which took about 30 minutes for our 1400 SF house. He took photos of the intake duct so we could see their condition. I will be scheduling a manual deep cleaning of the whole system next!"

"It's hard to put into a Yelp review how grateful we are to have found these guys. I am in a predicament to say the least. We hired just about the worst contractor we could have hired. We did our due diligence but they were masters of the con. What can u do? (Everlast construction - beware!!) The problems with our HVAC system were many. It wasn't installed to code, and was even set up in a way where if it was left as is, electrical fires and/or the previous hvac shorting out due to being wired so incorrectly. The guys at Jazz were able to take an incorrectly installed system, cut out my old one unit and safely remove it, then install a new hvac with all the corrections to every line. What we have now is an efficient heater that works - and isn't a fire hazard. Imagine that! This isn't even the nicest thing they did for us. Turns out, the ghost of my crooked contractor was still haunting us. We could not pass inspection without a hers test, yet the person hired previously to complete it, disappeared off the map. Jazz got a new one going, and spent several weeks tracking down all the people and paperwork needed to do one from scratch. Needless to say, it was unprecedented for them, no picnic, and they did it happily. Never wavered, never hesitated and always called back and kept us updated. I would recommend them to my mother. These guys will do a good job. They have a kind vibe and I have no reservations in giving them five stars and propping them up. Would hire them again. Thank you jazz! Edit: these guys have come By three separate times to fix more issues left by the previous inept criminally minded people at "Everlast construction." All three times, no charge, super sweet attitude and just supremely helpful. Hire these guys."

Install Boiler questions, answered by experts

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.
