Andrew has come to my house a number of times now to service my air-conditioning and heating units. He’s the most lovely young man. Professional, knowledgeable, the service was done in about 45 minutes and I always have peace of mind after he leaves knowing I’m going to be fine for the winter. He explains anything that’s wrong, that I need to do or any issues I may anticipate. Thank you Larry and Andrew Halpin and Jerry who also came and assisted.

Andrew seems so knowledgeable in everything he has done for me and explains everything. He is also very kind and seems to take pleasure in making things easier for me.I am very comfortable placing my trust in your company to do the right thing by me. It’s been a very difficult couple of years since Gary died and as you know I have had to take on everything myself. I am getting educated in many things thanks to you. Keep doing what you are doing.

susan - Wallingford, CT 06492
Andrew was here to clean our furnace today, and as always did a fantastic job. He found a few minor things that needed replacing and showed me the parts. Also, after 30 years of boiling hot water, he said our mixing valve needed replacing, must of asked a dozen plumbers and furnace people over the years with no results. These people are the real deal, so happy we have them!
Excellent service, thank you Larry!

Performed pm on oil furnace 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 4.0%o2 3ppm co 0 smoke

Brushed and vacuumed burner tubes Inspected and vacuumed burner compartment and surrounding area Checked electrical connections and safeties Checked gas pressure Performed combustion test Inlet pressure- 7.083 in.w.c. Manifold pressure- 3.10 in.w.c. When arriving the customer said the 1st circ pump was not working properly and had no heat for that zone. After investigating we found the bearing for the pump was very stiff and the coupling had snapped. After getting customer authorization we replaced the coupling and added oil to all circ pumps. After replacing the coupling and adding oil we found the bearing is still slightly stiff. Would recommend replacing the circ pump before the bearing completely seizes. Checked the coupling for the last circ pump and found the set screws are very rusted and corroded making it impossible to replace the coupling. Would recommend replacing the pump before the coupling fails.

Performed a heating pm on an oil furnace. (Furnace only did not service the water heater) Brushed and vacuumed. Replaced the oil filter, nozzle and strainer. Replaced the air filter. Started and checked the safeties. Performed a combustion test. 8.1% o2, 29 ppm, 79.4 efficient System is operating properly. When the burner started it, there was 7.3% o2 in the exhaust, when the blower turned on, it increased to 8.1% o2, indicating that there is a crack forming in the heat exchanger. There is a crack in the blower belt, the belt needs to be replaced. 4L-320

Upon arrival unit was off. Turned unit on and it was off on reset. Pushed the reset button and the unit started but was rumbling. Checked oil flow and had good clean flow. Checked the ignition transformer and it had a good strong spark. Checked the nozzle and found it had been dripping and was spraying at an incorrect pattern. Found some oil residue in the blast tube and small amount of carbon buildup. Cleaned the blast tube of all oil and carbon buildup. Replaced the old nozzle with a new nozzle. Started the unit up and performed combustion and smoke tests. Unit is working properly.

Upon arrival unit was on but the temp was satisfied. Turned temp up on the thermostat and the indoor and outdoor units kicked on. Put temp probes inside and turned power off to the unit. Inspected all electrical wiring for bad connections or breaks. All wiring was good. Checked the capacitor and found the compressor side was starting to get slightly weak. Cap is rated 45/5 and is reading 41.4/4.9. Would recommend replacing in the future. Turned outdoor power back on and watched unit start up. Checked temps and pressures. Supply air was 96* and return air was 74* showing the unit is heating properly. Checked operation of the outdoor sensing bulb and it is reading correctly. The condenser fan motor will turn off when the condenser goes through its defrost mode when operating in cooler outdoor temps. Unit is working properly at this time. Noticed refrigerant line connections are solder and not braze. R410a units are only supposed to be brazed
Larry H.
Performed a heating pm on a gas boiler. Removed and cleaned the burners and thermocouple. Checked the gas pressures. 3.0”wc at the manifold. Started and checked the safeties. Performed a combustion test. System is operating properly. While testing the boiler, the pilot flame went out. The thermocouple recognizes the flame very quickly. The pilot flame is not very large and was blown out went the main burner shut off. Tried adjusting the pilot flame but it did not change. Recommend replacing the gas valve. Picked up part. Removed and installed a new gas valve. Started and tested several times. System is operating properly.

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 While performing the maintenance we found very high levels of rust in the oil filter canister. Brought the customer down and showed them the rust. Recommended getting a sludge and water additive. After getting customer authorization we added the additive to the oil tank. Also found the chimney liner has started to slide down and needs to be fixed by a chimney person as soon as possible. Recommend having the company that installed the boiler to increase the piping size between the boiler and the manifolds.
