"Brian showed up on time and was very honest and friendly.  He performed the seasonal maintenance on our AC which was installed a few years ago by a different company.  I appreciate that he gave us an honest assessment of our system.  He was very thorough in what he did, going through each component.  We have a split air return system and the original installers had blocked off one side to meet the SEER rebate requirements, but makes the noise level a little louder.  I asked Brian if we should open up the 2nd side and he took the time to do an evaluation without charging us extra.
We were very happy with the service and price we got and feel we can trust Brian.  We'll be using Absolute Air from now on.

"My water heater was leaking but glad that I contacted water heater only. I called at 10:00am and by 12pm they were here installing my new water heater. David from Water Heaters Only came in the afternoon of 6/12/18 and it took 2 hours to install to city and state code. He had all the parts and tools to change the water heater on the spot. Old heater was taken away and new heater installed by 2pm.. I would highly recommend Water Heaters Only. They were very professional and courteous."

Thermostat screen went blank-furnace and A/C wouldn't come on

Chris arrived within 1 hour of my call and checked the furnace first. He found a blown fuse and no power to low voltage wires inside the unit. He then checked the thermostat and found it was no longer working. Chris replaced the fuses and the thermostat with a similar unit and tested the entire system. He then checked my A/C unit for Freon levels and found and repaired a wire that had come loose.

Chris was very pleasant to work with and explained what he was checking and why as he went along. He explained how the new thermostat worked and provided me with both the installation and operating manuals. Great service!

"Evening of Valentine's Day we learned our water heater had broken.
Called Bob & Marc the next morning and had an appointment of 3 pm. They were available earlier, but I could not get out of work any earlier.
Spencer was on time and got right to work. He was very professional, careful and friendly.
He assessed that the water heater was broken, drained and removed the old one and installed the new one.
He made sure that the TPM piping was exact, fit and would last. He was very helpful in explaining what he was doing and was even very helpful in providing advice on how to extend the life of this new water heater.
He cleaned up and all that was left was a professionally installed water heater that has been working great.
Thanks for the quick, friendly service (also be sure to use the 10% off coupon found on their  Angie's list page).

"He arrived and first tested the pilot to make sure it was functioning properly. It was not due to small leak that would extinguish the pilot. He then purchased a new water heater and installed it. He made sure that the earthquake strappings were properly set and took the defective water heater with him for disposal.
He was extremely polite and left the work area cleaner than it was when he arrived. This is the 2nd time that I used All Pro and in both instances the technician was prompt and efficient. I would not hesitate to use this company again.

"They were really good. They were helpful and really quick on getting back to us. We called him on a Tuesday and they came out on Saturday to get the job done. There was one hiccup with the installation. They felt that they would be able to use the hand lift, but when they figured out they wouldn't be able to use the hand lift, most instantly he went and called for a crane and we had a crane service set up the same day, so nothing slipped on the schedule. They were not the cheapest, but their service was satisfactory."

"On time and honest. I have very old but still working systems (20+ y.o. a/c and 30+ y.o. furnace). I told the technician that I use them infrequently. He was practical and suggested that I replace both systems when one of them quits working. Didn't try to up-sell for services I don't need. Suggested some services, but at the same time, didn't push for it since the systems are at end of life. Overall I felt comfortable doing business with them in the future."

Install Boiler FAQs, answered by experts

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.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

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, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.
