"We hired AC Dave to install a heating & cooling unit, after using them for our old unit's maintenance for years. It was a unit that. went on the roof, so installation was no small task. They did a fantastic job, kept the area clean, were extremely courteous, and we felt like we were hiring family to help us out. They pulled all of the permits which cost extra of course, but it saved us the hassle of dealing with the city and handled the post work city inspections."

"My water heater was leaking but glad that I contacted water heater only. I called at 10:00am and by 12pm they were here installing my new water heater. David from Water Heaters Only came in the afternoon of 6/12/18 and it took 2 hours to install to city and state code. He had all the parts and tools to change the water heater on the spot. Old heater was taken away and new heater installed by 2pm.. I would highly recommend Water Heaters Only. They were very professional and courteous."

"I've used them a couple of times. I don't think they were the cheapest. It was a big job, so at least three people came to complete the service. It was very clean when they left. They were very punctual, they cleaned up after themselves. They had to cut a hole in our attic; they installed an attic door that we provided to them at no extra charge because they needed to get up there anyway. Their estimator was really friendly knowledgeable, he was excellent."

"We received about six estimates over the course of a year before choosing to work with Darrow and Mirsky Heating & Air Conditioning. His bid was considerably less than the others, but we chose Mirsky over the bigger companies because he is a real person who treated us like real people and more than just a sale. Darrow took the time to explain he recommended the system he installed and why we didn't need all the bells and whistles other companies were trying to force on us. The work took a full week with permits, when we'd been quoted 2-3 days (by everyone), but we didn't mind. The rule of the triangle says fast, cheap or good -- pick two. Darrow didn't charge us a penny more than the original estimate, despite the many surprises our old setup and the inspectors presented. It's only been a week or two, but our new system is shipshape and working great, just in time for the first heatwave of summer!"

"Joe was punctual, polite, and very helpful. He took a little while to diagnose the problem with the heating unit, but once he figured it out he had the part ready and the installation underway (he first told us what the part would cost and asked permission to go ahead with the repair- which I appreciated). He tested the unit when he was done to make sure it was the right fix, which it was. Then we asked if he could also look at the air conditioning unit while he was here, since it stopped working at the end of last summer. He took some more time to fix that one, which was even harder to diagnose. But, he kept testing until he found the problem, and in the end we had 2 operable units that will save us from another service call in the busy summer season. It was worth the money.

"Very positive experience with Andrew at DNA. He provided me multiple solutions to help correct our heating system issues given the age of our home. We ultimately replaced our unit and I have never seen more care taken by a contractor to help keep our home clean and free from dirt and dust. Every time DNA would enter my home they wear shoe covers; when they replaced the furnace they installed temporary plastic sheeting walls to isolate the mess from the install to a minimal area which they also cleaned after completion. As I mentioned, the cleanest contract work I have ever had. Additionally, very well mannered and great attitude. I would hire them again without shopping for quotes."

"The representative from Baltica arrived on time. Quickly diagnosed the problem (where previous plumbers could not), fixed the water pressure valve, advised me on do's and don't in use of the Noritz system. He also advised me that I should change the cap on the water heater, which was confirmed by the Noritz representative when I called the company. I would recommend Baltica any day to any one. Knowledgeable and courteous technicians. Reasonable prices. If you have tank-less water heater, don't use just any plumber, use Noritz certified technician. My heaters were previously incorrectly installed by licensed plumber, but he did not have experience with tankless."

"The most professional, nice, clean and knowledgable crew came on time, had all of the equipment, had a can do attitude and it was a painless, great experience. I highly recommend this company to anyone. I have never worked with such a great crew and we got more than we could have hoped for by going with them. They were a one stop answer to the awful process of trying to decide what type of air/heat to install in an old house. They took care of it all and the price was absolutely fair!! Rudy, Joe and Matt are amazing - they really impressed us! We had several contractors come and the process was so laborious with needing to have sub contractors, workers, etc. When Matt came to give us the estimate, he told us exactly what we needed, how much it would cost and how long it would take. He brought a crew so it could all be done and each one was amazing with the care and knowledge they have. It was perfect and like I said, a one stop shop. One meeting, one day installation and done!!!"

Install Boiler questions, answered by experts

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out
