"Never having had to hire someone to fix my AC unit only to install it (and the company was not reputable), I had serious trust issues. Action was the only one to contact me of all the suggested companies. That made me even more suspicious! They were able to fit me in for the next day. Hmm, more hesitation. But I rested in Action's good reviews on HomeAdvisor and kept the appointment. I was so happy I did. Mike was fantastic. He was personable and extremely informative. He knows his AC and heat pumps really well. I look forward to having them back in a couple of weeks to clean my furnace and do some cleaning and troubleshooting on a Hearthstone gas fireplace. When one finds a company one can trust, well, stick with them and get what needs to be done, done. I am so happy to have done something so out of my nature, like trusting HomeAdvisor. Thank you, Action Plumbing, Heating, and Airconditioning!"

"Brady and Casey are an awesome team. They came a long distance when the locals couldn't or wouldn't. They're friendly, extremely knowledgeable and if they were closer, they would be our regular furnace experts!"

"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.

"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."

"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.

"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 questions, answered by experts

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

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.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.
