"Bait and switch pricing and now they quoted $155.00 to replace sprinkler valve upon arrival technician wanted much more than $155.00 to replace sprinkler valve. The company said that to cut out the valve and to re plum with a new valve with cost more money than $155.00. The company said that they were charging a $155.00 to remove six screws on the top of the valve and reconnect two wires. I would never pay a $155.00 to remove six screws and re attach two wires and that give me a clarity to anybody coming behind me about sprinklers valve replacement with this Company. This company need to be more transparent on the front side relative to what they do for a sprinkler valve replacement costing $155.00."

"We spent 14K on two new AC units for our house in 2021. We had to get the technicians out almost every year and multiples a year because something is always wrong. Some technicians were not experienced enough to diagnose the problem and wasted hours at our house. They also made careless mistakes (not connecting the draining pipe back in the attack) in Aug 2025. We had to run very loud fans for 5 days just to dry the water leak from the attic to our ceiling. The same technician was sent out in Nov 2025 and made the same mistake again. Now our ceiling is leaking again. The customer service did not even acknowledge or apologize for what we are going through. I am now worried that repeated leak may have caused permanent damage to our house. I do not recommend this company."

Boiler Repair questions, 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.

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.

When it comes to bleeding a radiator, the goal is to let out trapped air rather than letting out the water. Naturally, some water will dribble out when you open the valve to let out the air. But you don’t want a lot of water to leak out. Just leave the valve open long enough that the hissing noise stops, meaning the air has escaped, and just a dribble of water comes out of the radiator.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

At minimum, you should plan to have your HVAC system serviced once per year, usually leading into either the summer or winter before it sees heavy usage. If you live in a particularly cold, hot, or humid climate, consider servicing your HVAC system twice per year—once in the spring and once in the fall—to keep it running efficiently and prevent it from going down in the high-demand seasons. You can also schedule one-off services if you notice issues like uneven heating or cooling, poor performance, or strange noises from your equipment.
