"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."

"They were AWESOME. Same day service and quickly diagnosed the issue (blown transformer, since my furnace does not have a fuse). The guys were professional, courteous, explained what they were doing and why, and couldn't have been nicer. They finished the job quickly, and even installed the NEST which I had done wrong the first time, hence the need to call them. :-P"

"West Tech Mechanical Services (Joe Gonsalez) did an excellent job. This is the best investment that I have ever made for our quality of life in our home. Joe's attention to detail is evident in the care and consideration that he put into the duct work in the installation process. He thoroughly explained to me the importance of the duct work: location and size of the ducts to maximize the efficiency of the system that he was installing. Our home is an old home, and I really appreciate the care that he took in the installation process. I obtained 3 quotes for this job and West Tech Mechanical was in the middle. All the persons that came to our house were nice people. However, Joe's obvious attention to detail and how he explained the job is what convinced me that he and his company were the right people for the job. For a home owner that is considering the installation of a central air and heat system in their home or, any work for that matter on an existing heat and air system, I highly recommend this company as one that should be considered."

"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

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
