"From soup to nuts, the entire experience was made easy for us by the company. The salesman, Nick, came out to see us the day after my system kicked the bucket, and after checking out the system, he presented me with a few different options, and without using fancy words, explained everything plainly and easy for me to understand. After I discussed things with my wife, we called him a few hours later to give the go-ahead, and he had us scheduled just 2 days out. The installation team arrived promptly at the scheduled window, and took care to treat our house like it was their own. Drop cloths were used to protect my flooring, and after the job was done they made sure to remove all the debris from the job so nothing was left. After the job was done, the job foreman took me around and showed me everything that they did and explained the function of the system, and when I had questions, they explained plainly and without complaint or exasperation. They treated me and my house with the utmost respect. I highly recommend this company for any HVAC needs anyone might have."

"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."

Boiler Repair 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.

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.

The difference between a heat pump and a boiler is simple. A boiler often works with a furnace as part of a heating system. Some HVAC systems also have an AC to cool the home in addition to a boiler. A heat pump is unique as it works as both a heating and cooling system, altering ambient air to a comfortable indoor temperature.

Air trapped in a heating system can lead to reduced efficiency, uneven heating, increased wear on components, strange noises, and even complete system failure. This trapped air disrupts proper circulation, strains parts, and can cause overheating. Regularly bleeding baseboard heaters and furnaces can prevent these issues, ensuring efficient operation, even heating, and prolonged equipment life.

It's possible that your oven's gas ignitor will wear out before the rest of the appliance. An ignitor may last about eight years before it needs replacing. In some cases, cleaning the ignitor to remove any built-up food and debris may help to prolong its life. Replacing the ignitor in a gas oven costs an average of $200.
