This Goodman 13 SEER Heat Pump condensing unit is a new installation. The inside Goodman air handler attached to the heat pump condenser via line set was also replaced. It was replaced with this new Goodman heat pump. Its not a good idea to put a new high SEER air conditioner or heat pump condenser without matching it. It should be matched with a properly rated and efficient air handler especially the coil. (more…)

- Basic electrical safety and standards for wiring color
- The function of each wire terminal on the average thermostat. Additionally highlighting some of the differences in those functions from manufacturer to manufacturer.
Sometimes the thermostat is not the problem. Therefore please check this article for a checklist of things to check before calling a heating and cooling repair service.
Air Conditioner Ductwork Leaks | Leaky Duct Work - A good consideration when replacing the air conditioning system is the duct work.
Duct work seems to be the most ignored part of an HVAC system. However, it is a very important consideration in this age of new technology and higher energy efficient equipment being developed and manufactured. You can have the most energy efficient engine but if its in an old 60 or 70’s model car your efficiency is going to suffer. The same is true with HVAC systems. (more…)
How Air Conditioning Works – AC’s work by removing the heat from the space they service. An AC is simply a big refrigerator that uses the process of refrigeration to provide cooling for a building. AC’s work by using direct expansion coils or chilled water coils to absorb and move the heat from the air as air is blown across the coils. Types of air conditioner systems that use direct expansion coils for cooling are window units, split system air conditioners, package unit air conditioners, packaged terminal air conditioners like the air conditioners used in hotels, and mini-split ductless AC’s. Essentially, an air conditioning system works by removing heat from the air. (more…)
HVAC 3R NEMA Rated Control Panels
HVAC 3R NEMA Rated Control Panels - These control panels offer resistance to inclement weather. They house the DDC controllers for two small chillers and two air handlers. The chillers provide chilled water for air conditioning to the air handlers. The controllers offer energy management for the air conditioning system. The controllers were mounted outside for a few reasons. The main reason was because this location was closest to the HVAC equipment which provides air conditioning to the building. The secondary reason was because there was no safe or ideal location to install these panels inside the building. (more…)
HVAC Damper Actuator for Economizer Free Cooling
This damper actuator controls a free cooling damper for an economizer. It is part of an economizer damper system which allows free outside air cooling when the outside air temperature and humidity are ideal. In the Fall and the Spring when the outside air temperatures are mild it is unnecessary to run the air conditioning system to cool the building if the system is set up for free cooling. The air conditioning system has duct work running to the outside. When the control system program calls for free cooling the outside air damper opens and the system draws in cool air from the outside. Another damper directs the return air, which originates inside the spaces of the building, to the outside. This brings cool conditioned air into the building while exhausting the warmer air to the outside. Another action that the control program initiates is the lockout of the air conditioner or mechanical cooling.
White Rodgers & Honeywell Thermostats - Which type and brand of thermostat do you get when selecting a new thermostat? To do that you have to know what kind of HVAC system you have installed for your heating and cooling system. Do you have a boiler with baseboard heating or radiators with the boiler combination? In addition to the boiler do you have an air conditioning system with duct work or a mini-split ductless system? Do you have a heat pump system? Do you have electric baseboard heating? Do you have an air conditioner system with electric heat? It is important to know the answers to what kind of HVAC system you have installed in your home. (more…)
Air Conditioning Preventive Maintenance | HVAC Spring Cleaning - Do You Benefit from Maintenance Agreements?
Air conditioning preventive maintenance is a thorough check of the air conditioning system by a professional HVAC Technician. The technician will check the following:
Central Air Conditioner Prices | HVAC Buyers Advice - So you are looking to buy a new central air conditioning system? You want to know the price of the new air conditioner after it is all said and done. The complete price of the new air conditioner after its installed and the contractor walks out the door? The price of a new air conditioner is a popular subject. We get several emails every month asking how much it would cost to install a new air conditioner.
First, it is a loaded question. No air conditioner installation job is the same. Some air conditioner installation jobs being more difficult than another air conditioner installation job. The fact is, I cannot give anyone the price of their new air conditioner without first seeing the job. The fact is no one can give you a fair and reasonable price of a new air conditioner cost without first seeing the job. The must see it first and then do a little homework.
