Duct Work and High Ceilings | HVAC Duct Work Systems

Duct Work and High Ceilings – I did not see any reference to my question and would appreciate a response as soon as possible, as due to medical situation, have to make a decision soon. We own an OLD house with 13′ ceilings in a large part of the home and 11″ ceilings in the LV/DR and BR. We are oscillating on where to place the ducts….Floor or ceiling. It appears to be counterproductive to me to put the duct work in the ceiling since it will have so far to go. We are looking for the most cost effective, not upfront cost but operating cost, solution. In addition, we are considering DF heat pumps. The house will need 2 or 3 to be zoned correctly. Please let me know about the duct placement and thank you for your help? (more…)

Closing Off Part of the House To Save Energy on HVAC | HVAC Efficiency

Closing Off Part of the House To Save Energy on HVAC

Closing Off Part of the House To Save Energy on HVAC – I have a Heil gas/electric package unit in my home. I, particularly, want to know, if I can close off a section to save on heating. Heating dealers have not been helpful as they hedge on whether and how this can be done with the system still running at it’s most efficient. I have closed doors to seal off area. Then closed floor registers. Should I also close air return in that area? I just read this should not be done at all as it decreases units efficiency? Will you please advise. I am thinking of closing off part of the house to save energy on HVAC. Thank you. (more…)

Heat Pump Troubleshooting Advice | Heat Pump Repair

Heat Pump Troubleshooting Repair

Heat Pump Troubleshooting Advice: Before calling a heating and air conditioning company, check the following:

  1. Check selections on thermostat. Ensure that it is set to the desired settings.
  2. Check power supply. This can include a circuit breaker and or/a regular looking wall switch close to the unit
  3. Check for freezing up of air conditioner or heat pump units. If the air conditioner or heat pump unit is frozen turn it off. Check the air filter(s) to make sure they are not clogged or obstructed in any way. If you find no problems leave the unit turned off and call a service company.
  4. Is the air handler blower working good and blowing air out of all of the supply vents? If not or it is weak then you likely have an airflow issues. Always make sure you have a clean filter and that all of your supply vents are open and unobstructed. If this is all good then you have another problem with the airflow. Maybe a bad blower motor or the unit is freezing up inside the evaporator coil. In any of these cases it is time to call an HVAC repair service.
  5. Is the condenser fan motor turning at the heat pump condenser? Word of note – sometimes in the winter or when you have the heat pump in heating mode the fan will not turn while the compressor is running. This is normal and a part of the automatic defrost mode for the heat pump. If the fan is not turning but you hear the compressor running then something is wrong (unless as noted above with defrost mode) and you need to call a professional.
  6. Other things to look for with some issues regarding heat pumps include a condenser with excessive ice on the coils in the winter. This means the defrost mode isn’t working properly and may need a minor adjustment or a rapair altogether. It is best to call a pro to fix that issue. In the summer if the evaporator coil has ice on it or any of the copper pipes have ice on them then you have a problem that needs the attention of a professional.

How DDC Status Works – DDC and Status – Is the Device On or Off

How DDC Status Works? DDC Status Methods and Types

This is a current switch sometimes referred to as a CT switch.

The basics of DDC include learning about the status of a fan or a compressor or pump. How does a DDC controller read the status of the device it is monitoring? There are several ways to prove a device is running and some pros and cons of each type of device used to monitor on or off status. This is a basic DDC guide or reference to help a person understand the basics of DDC status and how it works. When one learns how DDC status works they can improve their troubleshooting skills. Too many maintenance technicians and others including HVAC technicians don’t understand DDC systems or building automation systems and are therefore crippled when it comes to troubleshooting DDC systems. High Performance HVAC hopes to change that and help HVAC techs and HVAC maintenance staff learn the basics of DDC systems including how DDC status works. Once someone understands the basics about DDC a light will turn on and they will see that DDC is not really rocket science.

Hot Water Boiler Reset Control

Richard,
We are looking at replacing our boiler with a new boiler. The HVAC contractor, I suppose he is the salesman for the HVAC contractor, is trying sell us what he refers to as a reset control for our boiler. He tells us it will save us more money by making our boiler more efficient. I think I understand how it works but my wife is not entirely sure about it. Can you tell us what you think about a boiler reset control and how it works?

Thanks and we have learned so much from High Performance HVAC. Keep up the good work.
