Team Enoch is an electrical, plumbing, HVAC and roofing services company that is passionate about providing the best value and service in the industry. Our technicians are licensed and insured. We would love the opportunity to give you a free estimate over the phone. Give us a call or send us an email with the specifics of your job.

"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

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.

Although boilers can last 15 to 20 years when maintained properly, you may run into some common problems like oil burners and transformers malfunctioning; cracks in the heat exchanger; clogs in the heating oil pump, burner nozzles, or fuel pipes; loose wiring connections; and damaged valves. Many of these problems can be caught early on during annual maintenance services. You might also have an issue with your fuel source if you have a gas or oil boiler. Make sure your other gas appliances are working or that you have oil in your tank.

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.

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.

Clean regularly, check for leaks, and schedule annual inspections for safety and efficiency.
