Like many HVAC contractors, David Johnson Jr., the owner of Johnson Heating and Cooling, LLC, was brought up working on residential air conditioning systems. David's experience dates back to as early as 1992, when he was only twelve years old. David's father, David Johnson Sr. taught David that if he wanted a material possession then he would have to buy it himself, however, David's father did provide David with a means to make money by working in the HVAC industry. Because David's father raised him the way that he did, David developed not only a good work ethic, but also gained much experience in the residential air conditioning industry at a very young age. In 1996 David received his first HVAC license (ACCA certification for buying, handling, selling, recovering, and transporting CFC based refrigerants) at the age of 16 years old, and began to work by himself on jobs.

Residential Air conditioning systems utilize exactly the same technology as most commercial and industrial air conditioning systems, only, residential systems usually are the most basic instance of those technologies. Simplicity coupled with efficiency make for a very desirable combination to the purchaser, and that is what most HVAC equipment manufactures try to provide in their residential products. Johnson Heating and Cooling, LLC always tries to provide it's customers with simplistic, yet efficient systems, because simplistic equipment usually means that there are less components that can fail. At Johnson Heating and Cooling, LLC, we make a point to always provide the best equipment, materials, and installation to our customers. We don't believe in selling low quality equipment or materials because of ethical considerations, but also because it is bad business to sell second-rate equipment and materials.

The men at Johnson Heating and Cooling have installed hundreds of residential air conditioning systems, and have always left their jobs with satisfied and happy customers. When Johnson Heating and Cooling is called for service, our customers can count on us to be honest, fair, and skilled in our assessments and repairs. We always make our recommendations based on what is in the best interest of our customers.

Have you ever seen an air conditioning condensing unit that has become un-level? In our 20 years of experience we certainly have. So what is the solution? Johnson Heating and Cooling does not simply install condensing units by leveling the condensing unit's pad as well as we can, we take the extra steps to make sure that your equipment does not have problems for the decades to come. You've probably heard the old adage about one home that has a firm foundation and another that doesn't. We usually use concrete under our equipment pads because concrete makes for a firm foundation and because if the dirt under the equipment is disturbed, it will settle. The idea of using concrete to level the equipment pads is something that decades of experience have taught us to do, and it is something that we have never seen our competition do. Sure the total job cost goes up by about $20, but with 240 pounds of concrete under your air conditioning condensing unit's pad, it's likely to stay exactly where we put it, until it is replaced twenty years from it's installation date. Also, using a few bags of concrete under the condensing unit's pad will help to get rid of critters that always seem to make nests under the pads.

Another thing that we do differently than much of our competition is that we pull very deep vacuums on the systems that we install. What is a deep vacuum, and why does it matter? A deep vacuum removes nearly all air and moisture from the refrigeration circuit. Basically, it makes the area inside the pipes and coils inside your air conditioning system as empty as outer space, so that only the "stuff' that should be in your system is in your system. Many refrigeration oils are extremely hygroscopic, which means that they readily bond with H2O on a molecular level. Simply leaving a can of oil opened for a few hours in the summer will ruin a can of refrigerant oil, because it absorbs the humidity in the air so readily. When H2O is put into most refrigeration systems (even in such low amounts as what is in the air on a summer day) it reacts with the oil and forms acid, which will damage the entire system. Typically the acid does not kill the equipment right away, but instead cuts a few years off of the life span of critical system components, and also causes the system to lose efficiency. So how would you feel if you knew that your HVAC contractor wanted to save a few minutes because it was the end of the day and he had plans that night, so he didn't pull a deep vacuum on your system? Personally, I would be very upset. We never cut corners because we have a busy schedule or because it has been a long day and we want to leave the job early. Our philosophy is to treat our customers the way that we would want to be treated, and also if something is worth doing, it's worth doing right! Problems due to this issue are all too frequent, and with refrigerant prices sky rocketing, there is no such thing as a "cheap fix" for this condition.

Do High Energy Costs Have You Down?

With financing available, you could actually save money every month by having a new heating and cooling system installed in your home. Often we are able to cut our customers energy bills by so much that they will pay less each month than if they kept their old heating and cooling system. Typical air conditioning systems that are around 15 years old run at about 8 SEER, because of their design and loss in efficiency. The industry standard for any new air conditioning system is at least 13 SEER, at the minimum. Calculating the savings is pretty strait forward, just divide 8 by 13 and that is about what the new system will use compared to the old system. Click on the link to read more about what SEER means, and how it is calculated exactly.

For most home owners and even HVAC contractors, understanding effeminacy savings by upgrading a furnace can be a little tricky and confusing to say the least. When a 70% efficiency furnace is replaced by a 95% efficiency furnace, the logical deduction on energy savings would be to assume that 25% would be saved, but this is not true. If your existing furnace is 70% efficient, and your new furnace would be 95% efficient, the difference is not 25%. Divide 95% by 70%, and you will calculate that a new 95+ furnace would be 35.7% more efficient than the old.

As of 2013, it doesn't always make much sense to install certain efficiency furnaces. For example, with gas company rebates, government rebates and tax deductions, etc, it's usually almost the same price to install 95% efficiency furnaces as it is to install 90% efficiency furnaces. The programs are subject to change at any time, and they frequently do change, however, you can count on Johnson Heating and Cooling, LLC to give you the best information about the choices available to you.
