"Porterhouse Heating and Cooling was very professional and knowledgeable on the service provided. I used them to install my air conditioner unit. Eventhough, the unit was not my issue, they still came out and was able to find the issue and fix it. They were friendly, professional, and reasonably priced. I will definitely use again for any of my HVAC concerns."

"I am very please with the work by Integrity Heating and Cooling. They really have the interest of their members at heart and are willing to go that extra mile. The tech came out and did the cleaning on our furnace with no issue; he was courteous, respectful and knowledgeable. The tech happened to have the owner on the phone, and the owner took the time to thoroughly educate me on the importance of a whole house humidifier, which was installed same day and at an amazing price through their membership. I feel safe putting the heating and cooling needs of my family in their hands. They really do have Integrity. 10 /10 will be using them for years to come."

"The installation was done when promised and completed on time at an excellent price. I needed to call the installers out to take care of 3 issues that I found when checking the installation. This was done in a timely manner. Overall I am pleased with the new system although I have not had an opportunity to really test the A/C yet as the weather turn cool and it has not been needed."

Install Boiler questions, 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.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Costs depend on issue severity, parts needed, and labor rates.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.
