Scroll Compressor Best Install Practices and Premature Failures
Scroll compressors should last 15 to 20 years if installed correctly and the HVAC system it's installed into is maintained.
This video touches on HVAC/R system install best practices to avoid the premature failure of air conditioning and refrigeration compressors.
Our guest, Jeff Kukert from Copeland, takes us through some common issues scroll compressors have if installed improperly and/or not maintained. These issue include, compressor overheating, copper plating, seized bearings and more.
We touch on line sizing, nitrogen brazing, proper evacuation and decay test. Jeff also talks about how refrigerant charge is super important.

Carrier Rooftop Unit Troubleshooting and Faulty Condenser Fan Motor
Просмотров 1,9 тыс.14 дней назад
The building manager reported that this Carrier rooftop unit was blowing fuses. During troubleshooting of this HVAC system, it was discovered we had a dead short to ground on one condenser fan motor. Once the problem was discovered, the faulty condenser fan motor was isolated from the circuit. This allowed the Carrier rooftop to run in cooling mode and keep the HVAC system up and running.

When brazing a TXV (thermostatic expansion valve) it must be done correctly. We also discuss liquid line filter driers briefly with Jamie Kitchen from Danfoss. The TXV brazing tips included in this video include the following: 1. Getting the heat on and off quick 2. Pointing the torch away from the valve 3. Protecting the valve from heat with heat absorbing putty (WetRag Putty) 4. Ensuring ther...
Evaporator Delta T vs Evaporator Temperature Difference

Evaporator Delta T and Evaporator Temperature Difference are different. Some HVAC technicians, helpers, and apprentices can get them confused. Both readings are very important in HVAC troubleshooting and require knowledge of how to attain them. Evaporator Delta T is the measurement of two points of the same medium, like air or water. Evaporator Temperature Difference is the measurement of two p...
Discover The Ultimate Media Air Filter To Stop Particulate Bypass And Eliminate Pressure Drop!
Просмотров 7635 месяцев назад
An air filter and filter cabinet combo that has the potential for particulate bypass will create issues within an HVAC system. For instance, any dirt/debris that is not captured can get caught on the secondary heat exchanger of a high efficiency furnace and/or evaporator coil of an air conditioning system. This can plug the surface and also cause condensate management issues. Choosing a deep pl...

How Does Flame Rectification Work On A Heating Season
Просмотров 1,8 тыс.6 месяцев назад
Flame rectification is the process of changing an AC signal to a DC signal. During flame rectification, the ignition control will send an AC signal in the range of 90v to 120v, from the flame sense terminal. That signal is sent down the flame sensor wire and through the flame sensor, it is rectified using the flame as part of the circuit and allowing the signal to come in contact with ground. A...
Carrier Rooftop Gas Valve Replacement After Going Off On High Limit
Просмотров 2,5 тыс.8 месяцев назад
Last winter this Carrier rooftop unit was going off on high limit. There was a problem with the gas valve in high fire and there was also a problem with the bypass damper on this zoned system. The gas valve pressure would creep up slowly over time from 3.5" wc to almost 4" wc within a few minutes of operation. For this reason, it had to left in low fire. The bypass damper was stuck in a closed ...

    Never knew what the gas ballast's purpose was until I saw your helpful video. I've been working with high-powered 16kW Leybold screw vaccuum pumps for a couple of years and always wondered what that gas ballast is for. For servicing, we always had to change the air filter once a year, and boy, do they clog up a lot of grime.

    I stared my hvac business in Canada 12 years ago. I’ve always just wanted a balanced work life. I knew very little about business and hard to learn thru a lot of bumps. I was tired of working for somebody, counting on the weather to keep us busy. It’s so hard to get ahead in business, especially with the crazy economy. Here it’s hard to sell a 3 ton a/c system for 5000$. I see guys in the states that wouldn’t touch it for less than 10-15k. Business stresses me out. I’m tired of the rollercoaster and catch up game that always seems to be going on. Sometimes I wish I never got into this. There is a few perks for sure , but sometimes I just wish I stayed working for the man
