"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"We purchased a Big Deal on gutter cleaning.  We waited a couple of months to use it (waiting until all the leaves were down).  It took several calls to get a response.  I finally contacted the provider through the Angie's List Serve website, at which point I got a prompt and professional response.  From there, the company was very easy to deal with.  The service was scheduled within a few days, and the guys who came out to do it did a good job.  They let me know that they could install a better gutter system if we were ever interested, but did not do a hard sell.

"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."

Install Boiler FAQs, answered by experts

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.

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.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

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.

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.
