"Williams & Associates installed a Buderus oil-fired boiler and stainless-steel chimney liner. Bruce's design was a significant upgrade over my 35-year-old boiler system. He clearly explained the process and installation, and he was receptive to my questions. Bruce is knowledgeable, straightforward, and responsive. The price was very fair, considering the quality of the work and other estimates I had gotten. I would not hesitate to recommend Williams & Associates."

"Juan responded quickly on a Sunday afternoon. He was very knowledgeable and fixed the broken part. Fortunately, Juan had the part in his truck and was able to get my furnace working again. The service was impeccable! However, the weekend rates are expensive the service cost me $699 for installation of a $70 part. The 2-hour service call was $500 ($249 per hour)."

"Stephen responded to my call promptly and came to provide a quote the same day. He indicated that he could do the work that evening. However his price seemed high for the material involved, and turned out to be about twice as much as what I paid the company who eventually performed the work for me."

"Very well. I had an appointment for approximately 8 AM. They were a bit late, but had called to let me know, and it wasn't a problem for me. They spent well over an hour on the job. They took a ton of lint out of the vent pipes and the dryer itself. I'm pretty sure that whoever it was I had in last time did not open up the dryer to clean it. They also installed a "bird cage" around the vent opening on the side of the house to prevent critters from getting in. (I don't think I have had problems with birds getting in, but why take the chance?) They were very thorough. The job cost more than the initial estimate, but this was because my vent pipe was longer than I had realized. It was reasonable."

"The owner returned my call promptly and after discussing the services needed he emailed me a detailed estimate and answered all my questions. I was confident after speaking to Joe that the work would be done exactly as I had requested. His son, Anthony, was the actual serviceman and he was courteous and my questions were answered and together we agreed on the best plan to cover everything that needed to be done in the most efficient and least disruptive manner. He worked tirelessly to complete all the extra services I hadn’t thought of initially which involved cleaning the bathroom vents, replacing the bird guard on the outside of the dryer vent and also cleaning the refrigerator coils which it turns out were in pretty bad shape! He showed me pictures of before and after and the difference was remarkable. Although he needed to work longer to accommodate all my requests, he was kind and patient and did not make me feel guilty for adding extra work, although I felt bad that he had a very long work day! If you are looking for courteous, reliable,and professional service this is the company to choose!"

"Outstanding! The second time that I have depended upon Ambient. Naturally, while away taking care of aging parents, my wife reported the A/C was on the blink. Within just a few hours, Ray responded and got the A/C “back on track”. I returned home a few days later, Ray made it a point to come by on a Sunday....no extra charge!!!....to ensure that the A/C would make it a few days longer while he ordered parts. He and Zach......back a few days later....to complete an outstandingly efficient job of installation.....at what I believed to be a more than fair price!! Ray and Zach will go the extra mile....because they take pride in their work. And we, my family, could not be more pleased!! Thank you, gentlemen!"

"Not the best, but I guess not the worst either.
They did the door blower test which revealed different air leaks in the house. They sealed around some of the doors in the home, installed some door sweeps, caulked around baseboard registers etc. However, the work was far from consistent and less than professional in quality.
There are 15 registers / returns in the home and we were told they would caulk around them all, they caulked around 7. 2 of which the caulking was so thin that it cracked before the next morning.
There are 3 sinks in the house where pipes were supposedly "foamed and insulated" on their report. There is no additional insulation visible anywhere that I can see.
We are entitle up to 40 CFL light bulbs in the home, however, even the 30 they said they changed were not completed.
For example:
-there are 2 nightstand lamps in the bedroom. One lamp received a CFL and the other wasn't touched.
-there is a hallway ceiling light that was supposed to be changed out with CFLs, but still has the same old bulbs.
-downstairs bathroom still has all three original bulbs
-two bedroom ceiling fans that take regular "A" type bulbs all have the same bulbs
I sent an email to the gentlemen who came out to the house asking if we could at least receive the extra bulbs. He did respond and said yes, but never got back in touch with me. After the general overall experience I did not bother chasing after them for a few more dollars worth of bulbs. However, the whole point is not the money, its the fact that these were all listed on the report and not completed accordingly.
They did recommend an insulation company to come in and give us a quote and also told us about different programs offered from the state which would allow us access to rebates for making home energy improvements. All in all, I guess it helped us to know where the air leaks were in the house, but the overall performance of the team was simply sub-par. They were nice, polite and somewhat informative but by no means "wowed" me.

Install Boiler questions, answered by experts

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

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.

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.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.
