Carrier Air Conditioner Reviews - Consumer Ratings | Carrier makes air conditioners with efficiency ratings from 13 SEER all the way up to 26 SEER. 26 SEER is a very high energy efficiency rating for an air source central air conditioning system. This Seer rating comes with the Carrier Infinity series AC. As opposed to geothermal systems. They use R-410A in all models of the air conditioner line. Systems that use R-22 refrigerant are no longer manufactured because R-22 will soon be phased out.
Carrier does manufacture air conditioner systems for residential, light commercial, and heavy commercial applications. In the residential lineup, the super-efficient model lineup is named Infinity. The next step down being the Performance series. Carriers Performance series is the central air conditioner mid-range line. Then the Comfort series air conditioners are the Carrier economy line. Carrier also offers a builder’s grade lineup. Some features of selected AC’s are: (more…)

Goodman versus Rheem Air Conditioners - The first thing we need to do when comparing a Rheem to a Goodman air conditioning system is to make sure we are comparing similar models with similar features.
Each HVAC manufacturer makes various models from a builder’s grade unit which is usually the HVAC manufacturer’s cheapest model all the way up to the unit that has bells and whistles and some of these have bells and whistles for the bells and whistles. You simply want to make sure you are comparing apples to apples and not an apple to an orange. (more…)

Crankcase Heaters and Compressors | HVAC Refrigeration. Hello, I have a question about crankcase heaters and compressors. I am aware that they keep the refrigerant from saturating in the compressor when not running. However, if the refrigerant is R-22, it becomes saturated at approximately 40 degrees. We know the a/c is only operating at warm ambient temperatures. When it is off for the evening hours & the ambient temps stay above 40 degrees, why would one need to have a crankcase heater? Why do we need it on during this temperature range, or are crankcase heaters designed to be activated only during the colder months? Also, if one installs unregulated crankcase heaters (always operating), can this be a negative factor for the compressor life? (more…)

An outside boiler is prone to flooding
What Happens When My Boiler is Flooded - Richard, What Happens When My Boiler is Flooded? - Hurricane Irene was a disaster for us as we live in a Northern state that was hit by flooding from the rain of Hurricane Irene. As a result of the loss of power and the flooding, the basement was flooded.
Our boiler happens to be in the basement and we will soon need the heat. We have had a few contractors come by and look at the boiler with one contractor telling us we need to replace the boiler and another telling us we can rebuild the boiler. It is a little overwhelming given that winter is just around the corner and we need our heat. (more…)

For proper Air Conditioner Troubleshooting, you need to understand some basics of air conditioners. This includes basic refrigeration, electricity, electrical components and how electro-mechanical controls work. In addition, basic air conditioner components and air conditioner sequence of operation. Before troubleshooting, you need to identify the basic problem with the system. Aside from the basics such as blown fuses or a tripped breaker we will explore other areas to look at for air conditioner troubleshooting. Tripped circuit breakers for air conditioning systems are covered here. A good preventive maintenance program done periodically can help you avoid common air conditioning problems that require troubleshooting. (more…)

Heat Pump Problems | HVAC Heating & Cooling - Heat Pumps are very popular especially in the South where air source heat pumps are mostly favored over straight air conditioners with a gas furnace for heating. 
With a heat pump, one system can provide heating and cooling. Some people rely on a geothermal heat pump system or a water source heat pump. A geothermal heat pump extracts heat from the ground instead of the air like an air source heat pump works. (more…)

Heat Pump Systems - There are different types of Heat Pumps in use in both the commercial HVAC heat pump markets and the residential HVAC heat pump markets. The two main types of heat pumps are the air source heat pumps and the water source heat pumps (or geothermal heat pumps). Within the water source heat pump types there are several sub-categories.

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.

HVAC reciprocating compressors were the workhorse of the HVAC industry and when someone mentioned a compressor the first thing one thought about was a reciprocating compressor. This compressor has a piston(s) that compresses vapor and in the cases of an HVAC compressor, the compressor compresses the refrigerant vapor. (more…)
