"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."

"Pretty good overall, though there was delay in ordering parts and after installation, they had to return the next day to adjust cables in one of the furnaces which had gone out. All works fine now. The bill came in a bit under the estimate and there was no charge for coming out to make the adjustment. (Their initial call out to assess the situation was reasonable, ~$65 w/ tax.)"

"Office staff was very prompt in scheduling the estimate appointment and keeping us posted as to schedule. Estimator, David, arrived promptly, and his inspection was thorough. He was very interested in giving us the most cost effective yet appropriate system and was very clear in his explanations of the features he deemed necessary. The written estimate was sent promptly, and the installation appointment was set up immediately. Communication throughout was excellent. The efficient and courteous office staff kept us posted every step of the way. There were no changes or delays. Installers arrived promptly and work was completed within the time frame estimated. Before leaving, they made sure we understood how to work the thermostat and were available to answer any questsions throughout the installation process. David also arrived at the beginning and reviewed the procedure and follow up expectations. Greg and John were very neat and clean, not only in the house but outside in the area they needed as work space. The following day, work was rechecked by Charles and appointments for final CO check by city inspector and Progress Energy were set up. This was a very pleasant and thoroughly professional experience in every way, and we are very satisfied."

"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."

"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 FAQs, answered by experts

Yes, you can build a sunroom addition to your home despite living in a cold climate. Make sure to use high-quality insulation and windows and to supplement with sufficient heating from your HVAC system. The windows in the sunroom allow enough natural light into the room to help heat it most times without having to use the furnace. Even a small electric fireplace can heat the sunroom well enough.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

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.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out
