"Excellent! After contacting Vaughan, a technician was at my home within 3 hours. Anthony was professional and very knowledgable. He carefully explained and showed us the problem. Within one day, the parts were ready and Anthony returned to repair and install the AC. The work progressed smoothly and we received updates throughout the repair. We couldn't have asked for a better experience!!!"

"We found CLIMATE MECHANICS from their stellar reviews while searching for a knowledgeable and competent HVAC company. For years, we were dealing with a condensation problem with our LG mini split air conditioner, and no one could find the source of the problem. We can honestly say that we've never experienced a company like CLIMATE MECHANICS so committed to making things right. Nate, the awesome climate mechanic that came to our home, and Robert, the owner of the company, could understandably have walked away because they did not install the system and were not responsible for the problem. Nate worked for hours trying to locate the problem. In the end, after so many years of leaking, CLIMATE MECHANICS went above and beyond and resolved our ongoing problem. Toni, their wonderful contact person, told us repeatedly that Robert just wanted us to be happy in the end. And we are. Totally. Thank you Robert, Nate and Toni."

"The Botte crew were incredible! There arenâ t enough superlatives to describe the awesome job they did for us replacing our ductless system. It was a big job! We had 4 quotes and theirs was the lowest, but we didnâ t just choose them because of that. They were responsive and professional. One quote was $8,000 higher and they were going to take over a week to install. Botte did it in 2 1/2 days. They were polite, friendly, and professional. Cleaned up before they left each time and the results speak for themselves. I couldnâ t recommend them more highly! Tom D."

"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

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

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.

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.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.
