"Hired him to install new ceiling fans, replace light fixtures and hang a chandelier where there was previously just a can light. The crew was fast, clean and showed up on time both days - - and their pricing was reasonable! I was also impressed at their ability to solve problems as they arose...and to figure out creative solutions as necessary. Highly recommended."

"Cristian was very professional and verifed problem. I called Next Level because the quote given by Paul Mitchell's Aircare did not seem competitive. I was correct. Paul Mitchell stated I needed 4 lbs of refriegerant at $289/lb totaling $1156. Cristain at Next Level diagnosed the same problem, but stated I only needed 3 lbs of refrigerant at $125 toling $375., a $781 savings. I agreed to purchase annual maintenace form Next Level which provided an additional $50 savings on my bill and Next Level's Annual maintenenace for 2 A/C units was onlky $250 versus $260 with Paul Mitchell."

"The installers showed up promptly within the window they gave us, they replaced the upstairs ducting and installed dampers to balance the air (one room is a lot warmer because of the sun). We had multiple quotations and they were significantly better than the rest. This did solve our issue completely!"

Boiler Repair questions, answered by experts

It can be difficult to determine the cause of a coolant leak unless you have the unit inspected by a certified professional. Most coolant leaks are caused by wear and tear on seals and joints. This typically happens five years after a unit is installed. Additionally, faulty or worn compressors, evaporator coils, and condenser coils can also cause leaks.

Addressing gaps and cracks reduces heat loss and improves energy use.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.

Signs of needing a new expansion tank include visible leaks and a dull sound when you knock your knuckles against the tank (working tanks should sound hollow). A malfunctioning tank may also sweat with condensation, cause pipes to create loud noises when the system is turned off, and lead to very high-pressure readings on the boiler’s gauges. When in doubt, call for a professional inspection to find the source of the problem.

Attempting DIY fixes can be dangerous. Regular boiler maintenance can help prevent overheating, so schedule professional servicing as a preventive measure. In an emergency, telling occupants to leave the house is a good idea. Then, you can turn off the boiler and the gas or fuel supply. Let it cool naturally, and check the thermostat's settings. Ensure there are no obstructions around the boiler for proper ventilation. Monitor the pressure gauge; if it's too high, bleed the radiators if necessary. During this time, bringing in professionals for troubleshooting is also smart.
