Being new to the area we didn’t know who to contact. Once we found Xtreme Temp we were happy with the timeliness in scheduling. Larry was a great resource to understand potential issues and remedies to take to avoid further issues. He was very knowledgeable and able to explain how our system worked. Great experience. Thanks Larry

We have had X-treme Heating and Cooling for five years. In that time they replaced our A/C and have provided service of both our heating and cooling systems. They are a family owned business that go above and beyond. They have treated us as if we are family and are honest, reliable, trustworthy and pleasant.

Performed a heating pm on a Heat Pump system and a pm on an electric water heater. Checked the coils and air filter. Customer changes the filter. Blew out the drain. Checked the electrical components and pressures. Checked the capacitor rating-52/6 mfd. Checked the heating elements and amp draw 14 & 18 amps. 96* discharge with the heat pump, 112* with the heating elements. Checked the electrical wires , thermostats, and elements for the water heater. When checking the lower element, there was no power when adjusting the lower thermostat. Found the reset was tripped on the upper thermostat. Reset it and still no power to the lower. The upper thermostat is bad and needs to be replaced.

Checked the air handler, found the heating coil is leaking from the back corner on the bottom. The system is older. We will work up several different options, replace the coil, replace the system and install ball valves at the water heater.

Customer turned the thermostat up and the burner started. Checked the oil, flow and transformer, both are OK. Removed the nozzle assembly, and the nozzle was very dirty, which can disrupt the spray pattern and caused the burner to go off on reset. Replaced the nozzle, started and cycled several times. The system is operating properly.

We will install a Taco Leak Breaker on the cold side of the water heater and repair the the leaks on the Hot side above the water heater. The Leak Breaker will shut off the cold water going to the water heater when water is detected on the floor near the water heater.

Performed a heating pm on an oil boiler. Brushed and vacuumed. Replaced the oil filter, nozzle and strainer. Started and checked the safeties. Performed a combustion test. System is operating properly When arrived, the pressure in the boiler was down to 3-5 psi, which could cause the noise in the pipes. The valve going to the automatic water feed was off, turned the valve on and increased the pressure to 18 psi and the water pressure was still increasing. The automatic water feed is bad and needs to be replaced. There is a hi vent on the indirect water heater that has corrosion on it from leaking water. Recommend replacing the hi vents.

There was water under the return ductwork. Checked the humidifier and condensate pump. When the water was up to the point of the pump turning on, it was very slow pumping out. Blew out the drain line, it was not blocked. Checked the check valve. Tested the pump and it pump a little faster. When testing it again, it did not pump any water out. The condensate pump is bad.

A Goodman GMVC96 furnace in Wallingford was not providing adequate airflow. I diagnosed a failed ECM blower motor, causing the system to overheat and shut down. I replaced it with a new GE 5SME39 motor, adjusted fan speeds for optimal airflow, and tested the unit. The system is now running efficiently with proper air circulation.

Upon arrival unit was off. Customer stated they tried cleaning the air filter earlier today when the furnace stopped working. Turned furnace on and turned the thermostat up. Found the furnace was blinking 4 times for a limit switch code. Turned power off to the unit to clear the code and checked the limit switch. We found the limit switch had continuity indicating it is still functioning properly and is not stuck open causing the code. Turned power back on to the system and the code cleared. Unit started up with no issue. Cycle the unit on and off multiple times with no issues. Could be an intermittent issue with the limit switch starting. Took pictures of the limit and the furnace model and serial number. If the issue happens again recommend replacing the limit switch. Would recommend having a maintenance done on the system

Checked the system. The noise was from the circulator, there was 0 psi on the boiler gauge. Added water to the boiler and the noise went away. Increased the pressure to 20 psi. Inspected the boiler, there is corrosion on the top of the boiler between sections 2 & 3. Inside the boiler there was a spot between sections 1 & 2 that has an area that is shiny from water. There is a little air in the system from when there was no pressure, the system can draw air in from any area that is compromised by a leak. The boiler needs to be replaced soon. The pressure will continue to decrease over time. Also gathered the information for replacement and an electric hot water heater.

Brushed and vacuumed flue pipe and heat exchanger Replaced oil filter, nozzle, and strainer Checked all electrical connections and safeties Performed combustion and smoke tests 6.2%o2 28 ppm co 0 smoke When arriving for the maintenance we found the boiler pressure was at 4 psi which is low. Last year we found the autofeed was leaking water into the boiler continuously and valved it off. Since the autofeed is valved off the boiler lost pressure through out the year. Opened the valve for the autofeed and brought system pressure back up to roughly 18. Had to close the valve for the autofeed again as it is still allowing water through when the system is up to pressure. We also found the pressure relief is still dripping water. Recommend replacing the autofeed and the pressure relief

Today, I repaired a Carrier Infinity 96 furnace for a homeowner in Wallingford, CT. The unit was short cycling and not maintaining temperature. After diagnosing the issue, I found a faulty flame sensor and buildup on the burners. I cleaned the burners, replaced the flame sensor, and tested the system. The furnace is now running efficiently, providing consistent heat for the home.

Completed a duct cleaning for a home in Wallingford, CT. The homeowner was noticing excessive dust and musty odors. Upon inspection, I found heavy dust buildup and mold growth in certain areas of the duct system. Using a high-powered vacuum and antimicrobial treatment, I thoroughly cleaned and sanitized the ducts. The air quality in the home has already improved, and airflow is much better.
