Air Conditioner Sequence of Operation - When a technician is troubleshooting an air conditioner problem it is important that the technician understands the air conditioner sequence of operation for that equipment. When there is a problem with the equipment, including air conditioners, the technician will know the problem if the equipment or air conditioner does not follow the sequence of operation. Sometimes it is that easy, and other times it is not that easy when troubleshooting any HVAC equipment. However, it is important to understand the sequence of operation for air conditioning so the technician can troubleshoot the problem. (more…)

York Versus Carrier Air Conditioners - Every manufacturer has their own parts system and sometimes these parts are readily available aftermarket and sometimes the parts are proprietary and can only be purchased through the manufacturer of that equipment. Carrier is one of the HVAC manufacturers that has proprietary parts and sometimes you will pay a premium for those parts.
The manufacturer can hold the customer hostage especially when it comes to repairing the unit. Of course, York is one of the big HVAC manufacturers and they too have proprietary parts however the parts are usually more reasonable for purchase as far as cost is concerned so people would lean towards purchasing a York simply because the replacement parts are not sold at a premium where with SOME Carrier parts are sold at a premium and are not easily replaceable except through a Carrier dealer.

Trane Versus Carrier Air Conditioners - The first thing we need to do when comparing a Trane Versus Carrier is to make sure we are comparing similar models with similar features.
Each manufacturer makes various models from a builder’s grade unit, which is usually the HVAC manufacturer’s cheapest model up to the unit that has bells and whistles, and some of these have bells and whistles for the bells and whistles. You want to make sure you are comparing apples to apples and not an apple to an orange.

Condensing Unit Frozen Wont Turn Off - What you can expect to learn from Condensing Unit Frozen won’t Turn Off article: this article is an answer to a question taken from our email by a visitor to High Performance HVAC. We often use the questions we get in the email as a guide to writing articles. The topic is a condensing unit that will not turn off, and it is freezing up. From my experience in the field and using my HVAC knowledge, I offer the readers a list of what could cause this problem. We hope it helps you.
What’s the possible problem with a frozen air conditioner condenser that won’t turn off except with the breaker? (more…)

Heat Pump Sequence of Operation - Every electrical-mechanical piece of equipment has a sequence of operation. While some manufacturers of heat pumps vary slightly with their heat pump sequence of operation the overall sequence of operation for a heat pump is the same for most manufacturers. So unless you have a special type of heat pump (they are out there – the Acadia heat pump is designed for extreme cold weather temperatures up North like Canada) the sequence of operation for your heating equipment should be very similar to what is described here. This is the basic operation of a heat pump like you will find in conventional heat pumps.

Goodman versus Trane Air Conditioners - The first thing we need to do when comparing a Trane Versus a Goodman air conditioning system is to make sure we are comparing similar models with similar features. Each manufacturer makes various models from a builder’s grade unit, which is usually the HVAC manufacturer’s cheapest model up to the unit that has bells and whistles, and some of these have bells and whistles for the bells and whistles. You want to make sure you are comparing apples to apples and not an apple to an orange.
The next thing we need to do when comparing HVAC equipment is to look at the HVAC contractor installing the equipment. If you get a lousy installer or contractor, forget about the name brand because the HVAC system WILL NOT FUNCTION CORRECTLY and EFFICIENTLY if the installation is shoddy. Also, the unit will not have the same life expectancy, will fail prematurely, and will need replacing sooner than if the HVAC equipment is installed properly in the first place. Out of any buyers advice about air conditioning and heating equipment that someone can give you this is probably the most important part.

Air Conditioner Problems - As an HVAC technician I am aware of all the problems air conditioners can develop. Therefore, you will get a unique perspective on air conditioner problems. And hopefully, how to avoid these problems. 
Air conditioners have become a norm in today’s society. Forty or fifty years ago air conditioners were considered a luxury. Now there are building designs where the occupants must rely on air conditioning to remain comfortable.
Additionally, with higher energy costs it is important that our air conditioners are maintained. Hence, a properly maintained system uses less energy and repair costs are lower and less frequent.

Variable Speed GE ECM Motors - When you look at buying a new HVAC system it will surely arise when the HVAC salesman or HVAC contractor who comes to give you an estimate will show an HVAC system that has a variable speed motor or the GE ECM (Electronically Commutated Motor) installed in it. These are systems that have a higher efficiency rating than the HVAC equipment that has the typical electric blower or condenser fan motor. (more…)
