"Brian at Clear All was recommended by a friend and they lived up to the recommendation and beyond. Helped trouble shoot a broken boiler for my in-laws and once he saw it he highly recommended replacing the boiler. I knew this was not an up-sell as the boiler was in very rough shape. While the new boiler was obviously more expensive then the repair, the price quoted for the boiler, burner, install, and removal of the old system was very fair - too good to pass up and risk throwing good money at bad with a repair on a 20+ year old boiler. Contacted them on a Monday, Brian showed up on that Wednesday to assess the situation and the new boiler was installed and running by 5 pm Thursday. He kept me in the loop through the whole process even though it was my in-laws boiler install. He also took the time to evaluate the size of the house and recommended a much smaller boiler - the existing one was way oversized and therefore over-using heating oil."

"Highly recommend Joe! 30 yr old boiler died, leaving us with no hot water. Joe quickly came and provided quote for boiler and new Indirect water tank which we wanted replaced. His price was a lot more reasonable than other quotes I got. also was able to get project done the same week as quote where others were scheduling 1 to 2 weeks out. despite the supply house delivering the boiler late ( Joe stayed in contact advising progress) He still was able to complete the work when he said he would. Top notch guy, Fair and honest. finished project looks great and works as advertised! Have more work for him to do"

"I finally got to build my dream garage to store all my tools and have a cool hangout on Friday nights with the boys n a couple coors. Chris came and did everything from the bathroom and the heating system. I will definitely be calling him back to add a mini split in the future. He was professional, punctual and clean. Very knowledgeable you can tell he cares about his clients."

"Kason is truly the best. Not only does he answer every time we call for any issue, but he or Connor, show up the same day which is huge when you run a small business! We needed a walk in freezer repair at our catering business- Kason was there on Wednesday to investigate, called me the same day with an estimate and we had the install on Friday. He is meticulous, precise and very knowledgeable. Kason has checked in the last few days to make sure things are still running smoothly and the freezer is doing its job- where can you find better customer service? I know we are a CRS Mechanical customer for life now."

"East Coast Plumbing and Heating provided us with a great service on a big job of replacing our 30 years old furnace. Dylan was very accommodating and explained the process in a great detail. His estimate for the job was honest and fair. Dylan and his crew did the job in one day and did an excellent work for a reasonable price. We are very happy with this company and we will work with them in the future. I highly recommend East Coast Plumbing and Heating."

"TCC is as good as it gets. After several issues with our GC and the plumber he used, I insisted that we use ours to fix everything that was messed up and/or flat-out wrong in our house. He agreed and I immediately called TCC. First, Joe is the best when it comes to boilers and plumbing issues. He is extremely knowledgeable and very patient when someone like myself, who knows absolutely nothing about boilers, ask a LOT of dumb questions. He fixed an issue that we've been having since we moved into the house last summer - one that our GC's plumber has been to the house on three different occasions to fix and only made worse. I've recommended TCC to clients who needed boiler repairs, plumbing updates and such in their homes and all have been equally as pleased. Are they cheapest around? No. But I've found that, when it comes to contractors, you get what you pay for and if paying a little more means I'll have good service and it'll be done right the first time, then I'll pay it every time. TCC rocks!"

"I am writing to express my deep disappointment with the service provided by McGinley & Sons. Despite multiple attempts to resolve this issue, I have yet to receive the promised refund for work that was never completed. As a cancer survivor undergoing surveillance scans, the refund would greatly assist in covering my medical expenses. The lack of response and follow-through has added unnecessary stress during an already difficult time. In addition to this, I had to hire a lawyer to recover my down payment, which cost me additional money. Moreover, he did not offer to compensate me for the extra expenses, including hiring an electrician to install a wire for the heat pump he could not install. Despite repeated attempts to have the deposit returned, I finally received it after engaging legal assistance. I hope this review will encourage McGinley & Sons to address this matter promptly and fairly."

Install Boiler questions, answered by experts

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.
