"They came on a Saturday and diagnosed the problem at no cost. Then they saved us over $1700 by finding a replacement motor and controller and not buying it from Bryant/Carrier. They found one nearby and installed it on Monday. We had originally contacted one of the larger, established local firms who charged us just to diagnose the problem and wanted to order the OEM replacement. Even just replacing just the controller that way would have cost double what the motor-controller combo cost using All About. The markups on these parts is just ridiculous. All About Heat & Air earned my future business."

"Tim is the best service technician! He was out today today for a maintenance and service call. He is very experienced and clearly explained what was needed and to recap at the end of the visit! I first started working Sheer Comfort in 2023 when they installed a new AC & Gas furnace for my home. I obtained 5 quotes from highly rated companies before deciding which company to engage. I worked with Travis Shearer (owner) on deciding which options were best for my home and I was impressed with his knowledge, fair pricing and ease to work with. The project was well supervised by Carl and installed by David & Eli......they were all great to work with. Tonya in the office was excellent in keeping me posted on timelines and managing the coordination for permitting and coordinating with the 3 sub-contractors needed for running gas lines and electrical to connect my new furnace and for a plumber to make changes to my water heater from my old gas forced air system. Sheer Comfort is the best!"

"Purchase and installation of heat pump went very well. David came the very next morning after my call for help. He gave me the estimate on the best pump suitable for my needs plus all the equipment and labor to complete the job. The day of installation everyone arrived early. Each person had their specific part and each went right to work. The whole system was completed the same day. Everything was cleaned up and the old unit hauled away. Nick came to do the inspection after a week to see if all was running well. All were so friendly and professional. They did a great job. I have had a maintenance contract with Quality Air for several years and all the guys who come to my home have been friendly and professional."

"After a thorough review of our system by another company, I received an estimate from them to replace two bad capacitors and a contactor in our heat pump. The total was over $700, so I declined the repair service. I looked up the pricing on the parts and bought two of them for less than $50. I then called Mike's Heating and Cooling and spoke with Josh who gave me a price of $50 for the third part I needed and $85 to install all three. Less than 48 hours later, the technician DJ had them installed and our system is now working great. In the end I spent less than $200 for everything, which was significantly less expensive than going with the original Aire Serve bid. I am very happy with Mike's Heating and Cooling and plan to use them in the future."

"Zach is one of those men you have a good feeling about the moment you speak to him.  He came to give me an estimate a few days after I spoke with him and it was very reasonable.  He and his crew of two others were so incredibly nice when they arrived.  I had initially just needed the gas line for the kitchen range.  The day before they were to arrive, I had a dishwasher delivered by Home Depot that was not able to be installed.  I called Zach and left him a message asking if he could install the dishwasher as well.  So with hardly any notice, they stayed an extra hour and did that as well.  I was very happy with the work they completed and with how pleasant they all were.  I will definitely be using All Ways for all my future plumbing needs!  Honest and hard working!  Thanks guys!!

"They were able to come in, configured, and installed properly the water heater and the furnace. They contacted the company and registered me on the agreement. It was a lot better than I anticipated. I made them the contractor of my choice. I was lucky to find them."

Install Boiler questions, answered by experts

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

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.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

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.
