"They were extremely punctual for both the estimate, and the actual installation, with full explanation of how the machine works including the comparison between the cost of a tankless and a standard heater,. In addition, there has been some vibration noise (that only one member of the family can hear!) and they have been extremely thorough in working to lessen it, while being cheerful through the whole process, despite having to make extra trips to do so."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"First let me say I contacted 3 other HVAC companies for estimates. The variances in the SALESMAN's pitches was pretty amazing, but usually they were trying to justify why their bids were up to twice as much as as what was quoted by All Comfort for comparable equipment.
    Daniel (Co-owner) struck me as an honest guy with lot's of experience. I have some experience in HVAC work, and recognized he was trying to get me what I needed, not what he would like to sell me. The price he gave me was a bottom line price ... no hidden charges or line item descriptions. His quote was exactly what the final price was. He is not a highly polished salesman, just an honest experienced workman trying to make a living by delivering what he promises.
    They DID arrive a little late ... 10 minutes... but called me to say they would be there! They very efficiently removed the old system and installed the new units in a minimum of time, which was appreciated because it was 40 degrees with a 40 MPH wind. The new system operated without a glitch except the fan speed was a little high, so they returned the next day to adjust the RPM's from high to medium.
    Clean-up was very well done ... with the old unit taken to a recycling center. (Am I green or what!)
If you need a polished salesman ... call elsewhere. If you need a job well done, at least give them a chance to bid.

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.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

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 system size, efficiency rating, and additional features like zoning or smart controls.
