"We had a leaking 35 year old oil-fired boiler that needed to be replaced. This was just at the start of the heating season in 2021. We got quotes for price & installation dates from several HVAC companies Clear All HVAC supplied several boiler replacement options and also quoted an earlier delivery date than any other quote. We selected a boiler/indirect water heater combination that was significantly less than competing quotes. Clear All installed the system within a week and responded quickly to any concerns & questions we had. We highly recommend Clear All HVAC for anyone that needs HVAC installations, repairs, service and values good customer service. In our opinion they are outstanding and we will continue to use them as our go to HVAC Services company."

"Kyle P. did all the water related services. Last year he installed a water softener tank and this year installed a sediment filter and UV tank as well as an arsenic treatment tank. He is always on time, explains work thoroughly, he's neat about his appearance and how he handles the work environment. Kyle is personable and pleasant.Highest recommendation. This company installed the ductless midi's in our home 3 years ago and in every aspect they are fantastic."

"Steve and his team are real pros. Jason came out and talked us through the various install options, with a lot more thought and consultation than the other two contractors we talked to. In the end, the quote was higher, but we felt we were getting a better product, backed by a better company. Steve (the owner), Travis and Mike (installers) were pros too. Keeping us up to date, starting/completing the work on time, etc. The crew were super clean throughout the project. They even hooked up everything and reprogrammed my ecobee3 smart connected thermostats. Jason spent an hour on the phone with me about the unit and i know any of them would stop by if we needed more help. We were worried about what we heard about the noise factor with high velocity units and these guys take great care to design the lengths and add sound-dampening material to the last 3 feet of the vents. The whole system is super impressive. Couldn't recommend them highly enough."

"I called NRG Management and talked to Andrew around 9:30 AM, he was in my town by 11:00 AM. My heating system had seen the end of a 30 year run, and my family was without hot water. Andrew gave me a price for the job completed that beat any of the other companies quotes, I checked reviews and I felt comfortable to do business with Andrew and NRG. Andrew said he would be over by 7:00 PM to do the install, after he finished his workday. Andrew showed up with a new Buderus boiler, a Riello burner and 4 circulator pumps, a zone board and tiger loop with flex lines, all new plumbing with copper lines. This guy is Superman, after a full day's work he came to my home and did the install so my family would have heat and hot water, he finished at 4:30 AM, WOW. Andrew replaced my whole system the same day I called, he did a clean first rate job, and beat every other quote, my boiler room looks clean and professional. I highly recommend NRG Management and Andrew, the level of expertise on the equipment recommended and the install was second to none. I got my moneys worth, plus some = 1 HAPPY CUSTOMER. 5 Stars Thanks Andrew, The Harvey's"

"Matthew responded very quickly to my call and showed up promptly thereafter. He was very professional and worked diligently to get my boiler working again and the heat restored to my home. He was able to diagnose the problem rather quickly and fixed the issue, even going so far as to explain many of the parts he had to replace and made me feel very comfortable that my unit was running efficiently when it was all done. I would highly recommend NexGen Aire and plan to call Matthew again for future issues. Fast, efficient, and affordable."

Install Boiler FAQs, answered by experts

Costs depend on issue severity, parts needed, and labor rates.

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.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

Yes, you can build a sunroom addition to your home despite living in a cold climate. Make sure to use high-quality insulation and windows and to supplement with sufficient heating from your HVAC system. The windows in the sunroom allow enough natural light into the room to help heat it most times without having to use the furnace. Even a small electric fireplace can heat the sunroom well enough.
