The efficiency of air conditioning systems—that is, how well they transform electrical power into cooling power—has improved in huge leaps over the last twenty years. The change in efficiency from ACs in the ’70s and ‘80s to today’s special high efficiency models can be almost double. Even standard mid-efficiency air conditioners are far more efficient than the models of the past.
If you are planning to call an HVAC contractor in Delaware to install a new central air conditioning system for your home, we recommend looking into a high-efficiency unit. They cost more than mid-efficiency units, but if you have professionals to help you choose the right unit and install it, you’ll receive a return on your investment that will pay back the extra installation costs in a few years.
We want to preface this blog post by saying that all air conditioning problems are serious. All air conditioning problems require prompt attention. Not all air conditioning problems are necessarily equal, however. Case in point: the refrigerant leak. No AC issue is a welcome development, but few strike fear into the heart of the AC user quite as much as the refrigerant leak. The reason for this is quite simple. Refrigerant is what makes cooling your home possible.
The modern residential air conditioning system is a complex piece of refrigeration equipment. Any type of complex machinery is in danger of breaking down at some point, no matter how well it was built or how well it is cared for.
As the summer starts, you may have concerns about the performance of your air conditioning system and whether it’s better to have a new one installed this year. You may have noticed the AC didn’t work as well as you wanted last summer, or perhaps you think that the unit is old enough that continuing with repairs will be a bigger money drain.
If there was an air conditioner that never developed problems, we’d be the first ones to tell you about it. Until that time comes, of course, you’ll just have to rely on some good old fashioned air conditioning repair and maintenance services.
After last year’s summer began to cool off, there was finally a day that was the very last. Without your realizing, there was one day of the season that became the last day that you used your air conditioner.
Have you heard about the countless benefits of air conditioning maintenance? Did you know that getting air conditioning maintenance makes your AC more efficient? Makes it less likely to develop repair issues? Makes it last longer, in general?
An easy way to understand the purpose of refrigerant in your air conditioner is by comparing it to blood in the body. The refrigerant flows through the AC system, changing from a gaseous state to a liquid state, and leaves your home nice and cool as a result. Without the perfect amount, the system (or body) will fail to operate properly. However, this phase change is impossible without the compressor, the component that pumps the refrigerant through the system. In this analogy, then, the compressor is the heart. Likewise, a broken compressor won’t be cheap to fix. Before it gets to the point that you need to call an 
Are there some rooms in your home that always seem several degrees warmer than the rest of the house? Rooms upstairs and those facing the sun throughout the day usually get it the worst. In the HVAC industry, we actually have a term for those rooms: hot spots.
