"Mike was great. He took his time to explain what he was doing. I had a sediment filter installed and he replaced the pressure tank. He showed me how to check/replace filter as needed. He came by and diagnosed my problem without charging a service fee. He was very thorough and was not in a rush. His price was fair. He gave his professional opinion and did not try to "sell" me products that were not needed when I inquired about a water softener for my house. Great guys both him and his partner. I highly recommend giving them a call for your next plumbing job!"

"Devin Coleman was prompt, courteous, professional and well informed. He advised us and responded to our requests. His estimate was easy to review and he answered questions effectively. Triumph's lead technician, Andrew was clearly a professional who knew both the products and the complicated installation process. His installers included Josiah, Austin and Devin and they were all hard working and interacted well together and with me. I appreciate their attitude and the work they performed. We are delighted with our new system which effectively cools, heats and dehumidifies our home. I feel that this is the best purchase we have made in remodeling our home. Thanks to all of you!"

"They did an excellent job.  Instead of replacing an entire panel which would have been more costly and more labor intensive, the took the time to research the issue with the furnace manufacturer and were able to fix it quickly and much more economically.  They were professional to deal with and prompt in their service. 
They also did a middle of the night call for me sometime in December for a water heater that went bad and were efficient, prompt and very easy to work with.  Within two hours I had a new water heater installed and was back in business.

"The work was done neatly. It looks good. However, the plumber told me that condensation of this type can be acidic and we would need an alkaline filter. Because of circumstances we were in a hurry and had no time to discuss or verify this information. A previous contractor whom I called to ask about a new furnace told me he would add a simple pump and hose to the cost of the furnace for $60. The installed filter looks very sophisticated and I believe added a lot to the cost of the job. The invoice was not itemized. I neither asked for nor received a cost estimate of the work to be done. The work may be fairly priced and necessary. It seems excessive, but I did not investigate. The fault, if there is any, is partly mine."

"Jim is local.  It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job.  He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer,  Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.

"Tyler was quick to respond, polite, and communicative. He gave me a competitive estimate from the start, was clear about the planned work, and scheduled the furnace replacement quickly (within a week). I will use his services again and recommend his company."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

"The initial contact was very good, but then we were lost in the Sears' maze for a week and only after a few unanswered calls did we get back with the program. The contractor for the A/C work was Proulx Heating and A/C. They were outstanding in every way. Excellent work and with straight answers to questions, excellent follow-up to make sure the job was right. All of the contractor work was done on schedule. The A/C units are working great. I will recommend Sears and I will continue to use Sears myself. Tice L."

Install Boiler FAQs, 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.

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.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.
