While a cooling system that's too small is an obvious problem, many people don't realize that systems that are too large also pose problems as well. A system that is too large will not have to run very frequently to cool your home. That means it will cycle on and off...

Have you ever thought about the quality of the air inside your home? A new HVAC system can help you maintain excellent air quality, which the Environmental Protection Agency says is the No. 5 environmental concern in the country.

The typical central air conditioning system is a split system, with an outdoor air conditioning, or “compressor bearing unit” and an indoor coil. Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors...

Did you know that commercial absorption chillers for cooling can be either single- or double-effect? Double-effect absorption cycles are able to capture some internal heat to provide part of the energy required by the generator, and create the high-pressure refrigerant vapor.

If you have a central HVAC unit, it is very important to change the air filters at least once every three months. If possible, you should also invest in high-quality air filters that capture more particles than basic ones do.

Many believe that routine maintenance is not necessary. Believe it or not, as much as 80 percent of all air conditioning and heat pump compressor failures could easily be eliminated if the problems that led to the failure were diagnosed in the early stages.

In gas HVAC systems, the ventilation system includes the outtake vents and intake registers that allow cooled or heated air to properly circulate to cool or heat your house. Both heating and cooling units rely on healthy ductwork to properly distribute heated and/or cooled air.

It’s important to remember that your HVAC system will have fewer problems when you stay on top of the regular maintenance. If you’d like to set up a schedule for us to come out, we’re happy to discuss it.

Cooling and climate control have changed the way in which buildings and homes are constructed. In fact, because of air conditioning, buildings are no longer being typically designed in brick, which has cooling properties. High ceilings, breezeways, and transoms, as well as...

In thermodynamics, evaporative cooling is an adiabatic process, meaning that energy is only transferred as work and does not escape the system. The sensible heat of the air evaporates the water, converting it into latent heat in the water vapor.

Did you know that ceiling fans can help reduce energy bills in both the summer and winter? Ceiling fans spin counter-clockwise during the summer to circulate cool air and rotate clockwise during the winter to spread warm air throughout your home.

If you hear strange noises coming from your car air conditioner, have an air conditioning specialist look at it immediately. It may be an early sign of a compressor failure, which needs to be repaired to avoid further damage to the unit.

Did you know that one of the most common problems in older gas furnaces is dirty burners? Basically, as grime accumulates over time, the burner becomes less efficient and produces less heat. Regular servicing of older models is especially important.

When your HVAC equipment is on the roof of your building, it can be susceptible to additional concerns that the average outdoor unit may not face. Let’s talk about any special maintenance that may be necessary, or if you should expect to need additional repairs.

Did you know that there are basically three ways that water is drained from a portable air conditioner? In a self evaporating system the water is dispersed back into the air, with a condensate pump it is pumped out of the tank, and in a manual model you need to manually empty...

Enthalpy of vaporization is the amount of energy that must be added to a liquid in order to turn a substantial amount of it into a gas. Water has a large enthalpy of vaporization, allowing evaporative cooling to happen effectively.

Be sure that you know how to properly clean the filter for your heating and cooling system. Whether it's a permanent filter that can be washed or one that can be replaced periodically, proper filter care will extend the life of your system.

Unlike most furnaces, air conditioners are complex mechanical systems that depend on a variety of conditions to work correctly. If more heat is produced indoors either from having more people or appliances or because of changes in the house, the air conditioning unit may not...

These days, forced air gas heating systems aren’t as inefficient as they once were. In fact, the top models have AFUE efficiency ratings of up to 97 percent, meaning there’s only a 3 percent energy loss.
