Review of X-Treme Temp Heating & Cooling, LLC

Andrew was responsive, knowledgeable and respectful. He got the job done and his repairs look great. I give him 5 stars. My issue is that the cost seemed out of line with the work performed. With only minimal parts replaced, the job took just under 3.5 hrs. The price of $800 seems to indicate a labor rate of around $200/hr. I have not had much plumbing done over the past several yrs but that seems high. I will continue to use Xtreme but would like to see your invoicing break out parts and labor. Again the service was outstanding and the leaks have been repaired. Thank you

Review of X-Treme Temp Heating & Cooling, LLC

Larry Halpin and has been to my home now a number of times for furnace maintenance and diagnosis of problems over the years. He is always exceptionally polite, friendly, extremely knowledgeable, explains the problem in easy to understand terms and gets the job completed in a very reasonable amount of time. He leaves the place neater, cleaner and tidier than he found it. I’m always happy to see that it’s Larry when I have called for furnace issues. Incredible Oil referred Extreme Temp to me and I am very grateful to them. They are also a wonderful firm.

Upon arrival unit was off. Turned unit on and both units turned on properly. Found the condenser coil was plugged with pollen and debris causing the pressures to be higher than normal. After getting customer authorization we chemically cleaned the condenser coil. After talking with the customer they authorized the addition of UV dye to the system. Need to return to perform a UV leak search. Pressures were 109/329 which are within manufacturer’s specifications and there was a 16 degree temp difference between the return and supply which is good.

We will isolate and replace the working parts of the mixing valve. Also isolate and drain the pressure from the system and replace the pressure relief valve. Fill the system and purge any air. Start the boiler and test the domestic hot water and the zones. 120- 122* at the kitchen sink.

Upon arrival unit was off. Turned unit on and both units turned on properly. Checked the air filter and evap coil and saw both were clean with no obstructions. Checked the condenser coil and saw there was a small dirt buildup on it. Rinsed the condenser with water. Started and tested the unit. Refrigerant levels were within manufacturer’s specifications and the superheat was 20 which is acceptable. Had a 16 degree temp difference in the kitchen and 18.5 degree temp difference in the bedroom. Unit is working properly at this time. We did notice the compressor amp levels are starting to get close to the maximum allowed amount. The max amp level is 13.7 and on a 72 degree day the amps were at 10.7 which is high. The high amp level could possibly be causing issues on warmer days.

Upon arrival unit was turned on but only the air handler was running. Upon investigation found there was a mouse dead on the capacitor that had chewed up multiple wires. The wires were touching the metal of the condenser and had tripped the breaker. Reset the breaker and repaired the chewed up wires. Checked the capacitor and it was still good. Started and tested the unit and found it was low on refrigerant. After getting customer authorization we added 2lbs 8 oz R410A to the system bringing the subcooling from 1.3 up to 13.3 which is within the manufacturer’s specifications. Unit had 55 degree air blowing out and is working properly. Recommend adding UV dye to the system to figure out where the refrigerant is leaking from.
