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…)

Home Inspector HVAC Training
Thank you!! I am training to become a home inspector and the info contained on this site is helpful in identifying issues that require a HVAC professional to resolve. Read more…….
You’re welcome! I understand that everything at High performance HVAC is limited and there is so much more to learn about and for me to write about when I get the time for it. Don’t limit yourself to just what is contained on High Performance HVAC as there is so much more to learn as far as HVAC training and learning air conditioning and heating systems. Additionally, some of that knowledge you learn will come with experience so even after studying air conditioning and heating and other areas of home inspecting there is more to learn in the future that only comes with time and experience.

Residential Heat Pumps
Air Source & Geothermal Heat Pump Heating Systems
A heat pump is an electric cooling and heating system used to compress and decompress gas to heat or cool a house. This mechanical device pumps heat from a cooler to a warmer location and can extract heat from air, water or the earth. Heat pumps functions like an air conditioner in the summer and an electric furnace in the winter, thus encompassing both a heating and cooling unit in one device. The COP, or coefficient of performance, which calculates the ratio of heat output to electric power consumption, measures the performance of a heat pump. (more…)
High Performance HVAC Air Conditioning & Heating: Ask the HVAC Man?
Dual Two-Stage Split System with a Dual Slab Coil. Huh?
Very nice site!
Dual Two-Stage Split System – I have a question; my home was fitted out by the previous owner with a twinned system, and a thermostat (Totaline P374-1900) which was not designed to control discreet, paired units. I confirmed this with Totaline. The result is only one unit runs, and the second unit is never activated. It functions, but not automatically.
Your website mentioned dual compressors in one systems, and mine is similar, two independent compressor/condensers. Seeing the separate condenser units, I first thought the house was zoned, and later discovered both units feed into one Aspen BHA40 4-roll coil.
Besides the issue of the wrong thermostat, I’m having problems finding an HVAC person who understands these hybrid systems and will service it. Is this configuration that uncommon?
I live very near Houston Texas, so if you know of a local HVAC person with the skills to help me out – let me know.
PS – I checked with Honeywell about the possibility of their thermostats working with my setup. They emailed me – they would only work with a HVAC professional. I thought this was strange since they sell them in the hardware stores.
