"Climate Mechanics worked hard to make sure we had both systems replaced on the same day and before the summer heat started. Nathan provided excellent service and communication throughout the whole process, from the first visit through the install. We are very happy with our systems and are confident knowing we are working with a local company that will be there for the service and maintenance of the units."

"The job of the century! Martinelli’s crew did an outstanding job with our bathroom. From completely gutting our tiny master bathroom to finish. They completed our vision and then some. Mr. Steam steam shower, rain shower, Bain ultra air jet tub, porcelain and glass tile, marble vanity and marble shower floor. Recessed lighting and crystal vanity lights helped complete the look. I am so thankful for the hard work they put in to get our bathroom finished and could not be more grateful for the time they put in to get the job done by our deadline. Before and after pics attached to show their hard work!"

Mike performed all the tests relevant to our problem. (Fan is on, but not really forcing cool air.) This unit is 4 years old and installed by Hutchinson. Capacitor was shot or not really performing. He was able to replace rather quickly. Mike was here for a half-hour. Most of that time he advised me on questions and concerns regarding our systems (We have two.) and having a maintenance plan which had elapsed. So physical work was 10-15 minutes, he had the part in his truck.

This visit went well . Others (which have timed out on this site and are no longer available to be seen here on Angie's.) we weren't as lucky. Mike was efficient, knowledgeable, professional and was easy to get along with and understand his explanations.

Our system is still under warranty so that $234 retail price cost us nothing.

Install Boiler FAQs, answered by experts

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

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.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.
