"They destroyed the whole pipes that caused flooding to my neighbors. The water was off and every other day we need to go out to the street to turn it on. This company denied the responsibility but later reimbursed me for the first leak repair after employee acknowledging doing partial work. This project aims to address and fix the extensive leaks. Must be completely replaced, cause of leaks appears to be from over heating of the copper as locations are at ALL connections and bends in the pipe, too much to patch. You can contact me to this phone number: 9(16) 857-5652"

I was pleasantly surprised that the technician was the same gentleman I talked to over the phone so I did not have to retell what was wrong with my system. Jason my technician who is also the owner was great. He tested my system, knew exactly what was needed, and had it repaired the very same day. He did not try to sell me on upgrading my unit or a bunch of repairs I did not need. The service was fast, very reasonably priced, and I have had no issues since. Will definitely be having ThermoTech Solutions come out for all my HVAC needs in the future!"

Boiler Repair questions, answered by experts

Over time, a radiator can leak if turned off due to the built-up air pressure, which can cause water or coolant to leak. If your radiator leaks when it’s off, turn your whole system off and bleed the radiator, then turn it back on. If it’s still leaking, you might want to have an HVAC professional look at the issue.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

Both hydronic and electric hydronic heaters usually come with a higher price tag up front, but you can save more on energy costs over time compared to standard heaters. They also provide heat for a short time after the heater is actually turned off, making them more efficient. Additionally, standard convection heaters use electric coils to heat up the air, whereas hydronic heaters warm up water or oil which then heats the air.

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. 

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.
