"I called Mehmet based on the Angie's list recommendation and the terrific reviews. Mehmet worked around my work schedule and came after 5. He identified the problem and installed a new capasitor. He was in and out of here in 30 mins. A week earlier a rip/off big company (Varsity) claimed the unit could not be fixed for under $3500 and recommended I install a whole new system for $11,000. Mehmet's skill, reasonable price and honesty were well appreciated here."

"Luis is the man !! I opted for an urgent repair for the next 24-48hours at 9:45pm. I received a call from him 15 minutes later ready ready to come over and address the situation. I asked him if he could meet me the after work the next day between 1-3PM. He said I’ll be there. After speaking with him for a few minutes I can tell he was highly experienced and confident. Sure enough in no time at all he was able to repair my 60 year old boiler. I highly recommend if you have any heating and cooling issues DO NOT hesitate to reach out to him. Iam more than grateful and appreciative he was able to resolve my months long stressful situation. Got an issue call Natural Breeze ASAP!!!👍🏻"

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"All staff members we had contact with at Elm Air Conditioning were very polite. Installers worked efficiently and were well prepared for the task. After the job was completed, they thoroughly cleaned all areas where they worked. We were impressed with their service from start to finish and are looking forward to enjoying our new a/c."

Install Boiler questions, answered by experts

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.

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.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

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.
