We take pride in the quality of work and customer satisfaction that we give each and every customer. We are known to pay exquisite attention to detail while making customer satisfaction our top priority. 7 days a week. Call us today to learn more about how we can help you.

"KJM is the first company who responded to my inquiry on Angie's List. After taking to a couple of companies, I eventually selected KJM to replace an 80 ga electric water heater with a 50 ga hybrid electric water heater with a heat pump, partly because I read a review about Kurt helped out a senior fix a problem on a weekend even without charging her and I would like to support good people's businesses. It doesn't appear to me that many local companies have a lot of experience with hybrid water heater yet. Kurt appeared to be knowledgeable, and always communicated promptly. Kurt and Duke showed up on time on the scheduled date and did an excellent job replacing the water heater. They are pleasant and caring people to deal with. They cleaned up well and I would use them again. Actually I already asked Kurt to help fix a leaking faucet in the house, and I will update the review on whether they consistently deliver excellent service and value."

"The salesman was knowledgeable, professional and explained everything about the shower install well. I gave him a deposit of $3200. I did not hear from anyone so after 3 days I called but no one returned my call. Called back again a week later to cancel the order. Left a long message stating I did not want to cancel the order but was concerned because no one returned my calls. Finally, received a call from a regional manager. He connected me to a local manager who set up an install date a week later. The installers were polite and professional. Gave me some helpful advise. Job was completed in less than a day. The shower door came a week later. I have had the shower for over a month. It is beautiful. I love it. Quality work. I would highly recommend Premier Home Pros."

Install Boiler questions, answered by experts

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.

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.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

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. 

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.
