Why SEER Ratings Matter with New Air Conditioning Installation

Friday, May 30th, 2014

When installing a new air conditioning system, you have a number of important considerations to keep in mind, from the power load to the position of the thermostat. But out of all of them, the SEER rating may be the most important. It measures the efficiency of your system, which informs almost every other consideration you make. In Teaneck, air conditioning replacement services can discuss the specifics with you. But what is a SEER rating specifically? And more importantly, why do SEER ratings matter with new air conditioning installation?

SEER & New Air Conditioning Installation

The term stands for Seasonal Energy Efficiency Ratio, and it basically compares the amount of energy the unit uses in a given year with the amount of energy actually used to cool your home. The higher the rating, the more efficient the system. Most units have a rating between 7 and 24, though units made after 2006 must have a SEER rating of at least 13. (Older units are still allowed to have lower ratings.)

If at all possible, you want your new air conditioner to have a higher SEER rating than your old one. (It’s not difficult, especially if your existing system has been around for a number of years.) Your new unit should be more efficient in order to cut down on your monthly bills, helping you recoup the cost of investment. More importantly, the SEER rating will influence other factors involved with installation, such as the power load and the initial cost of the unit itself. You need to factor it in to almost every aspect of the decision, which is why you need to understand how it works early in the process.

Luckily, help is available. For Teaneck air conditioning replacement services, the experts at DB Heating & Cooling are ready to help. We have the knowledge and experience you need to handle all aspects of the project for you, and we can explain why SEER ratings matter with new air conditioning installation.

Why Are Parts of the Air Conditioner on the Outside of the House?

Friday, May 23rd, 2014

Air conditioners are a staple of 21st century life, but the specifics on how they work are often known only to professionals. Services that offer air conditioning repair in Teaneck can usually explain the details if something goes wrong with your system, but home owners can also educate themselves about certain particulars. For example, why are parts of the air conditioner on the outside of the house? The short answer is to vent hot air. But how does a unit designed to produce cool air end up producing hot air?

The components on the outside of the house usually include the condenser valves, the compression coils and the condenser motor. This is where the process of air conditioning begins. Refrigerant gas enters the valve, which places it under a great deal of heat and pressure, and then moves to the coils, where the heat is bled off into the surrounding air. The liquid – still under pressure – then moves inside, where it passes through an expansion valve and into the evaporator coils. As it evaporates, it pulls heat from the surrounding air, which can then be blown into your house to cool it.

That process only works if the refrigerant is in liquid form and it won’t reach liquid form without giving off a great deal of heat. Obviously, you don’t want any of that hot air in your air conditioner, since it will defeat the whole purpose of air conditioning. Hence, that part of the cycle is often left outside. The hot air can be vented into the outside atmosphere and the condenser array can do its job without interfering with the second part of the cycle (the one that produces the cool air). It’s a strange set-up but it makes a lot of sense in terms of efficiency. And with air conditioners, efficiency is the name of the game.

If you know why parts of the air conditioner are on the outside of the house, you also know that the delicacy of the system requires professional attention when something goes wrong.

How Does Zone Air Conditioning Work in a Centralized System

Friday, May 16th, 2014

If you’re in the market for a new air conditioner, you may have heard the term “zone control system” batted around. Or you may have seen a modular zone control system, with multiple small units placed in different rooms of a given house. Zone control systems offer the benefit of fine tuning your environment – setting one temperature in the kitchen and another in the living room for example – but if you own a centralized air conditioner, you may have thought that zone control isn’t compatible with your system. Nothing could be further from the truth. Upgrades exist that let you retrofit your central system with zone controls, allowing you to set different temperatures in different rooms and even turn off the air in parts of the house you aren’t using. If you’re looking into zone air conditioning, Waldwick has the services you need.

How does zone air conditioning work in a centralized system?

Your centralized system relies on a series of ducts to transport the cooled air. The ducts branch out from the unit itself to cover every room in your home, using hidden areas like the attic or crawlspace to hold them. When you upgrade to a zone control system, the technician installs a series of valves and controls at each junction to the ductwork, along with thermostats in each room to control whether the valves are open or closed. With them in place, you can achieve the same effect as ductless zone control systems, guiding the cool air where it needs to go or cutting it off from rooms you aren’t using. As a result, the air conditioner wastes less energy and allows you to tailor the temperature to suit individual comfort levels.

If you know how zone air conditioning works in a centralized system, you know how important it is to contact a qualified technician to install it. And if you’re interested in a centralized version of zone air conditioning, Waldwick has an answer with the experts at DB Heating & Cooling.

3 Reasons You Need Your Air Conditioning Installation Done Professionally

Friday, May 9th, 2014

You’ve put a lot of effort into making your home comfortable. Adding an air conditioning system can increase that comfort level tremendously – when it’s done correctly. When it’s not, you may run into some serious problems. Below are 3 important reasons to have an air conditioning installation in Oradell done professionally by a DB Heating & Cooling expert.

Top 3 Reasons to Call an Expert

Reason 1: Correct Installation

An air conditioning/HVAC system is not a simple mechanical device; it is complex, with multiple different components and many different parts. It needs refrigerant to run and has to be tied into your electrical and heating systems. The bottom line:  the margin for error can be wide – and potentially dangerous – when installing your own AC; the smarter, and potentially more economically sound decision, is to schedule an expert installation.

Reason 2: Time Consumption

A new air conditioning system installation takes time, and if you’ve never done this kind of work before, it can take a lot of time. How much time are you prepared to give up in order to properly install your air conditioning system? Are you willing to let your home be potentially hot and uncomfortable while you do it? A trained professional brings both expertise and speed to a new air conditioner installation, ensuring that the install happens quickly and correctly.

Reason 3: Calculating the Correct Air Conditioner Capacity for Your Property

Installing an air conditioner that is either too large or too small for your home can result in a number of problems that may require air conditioning repair down the road. To ensure you are getting the right size system for your property, a calculation of your home’s size, insulation and heat gain needs to be determined.  A professional AC installer does this type of calculation as part of his/her job, so it’s better to let an experienced specialist handle it.

3 Common Misunderstandings about Air Conditioning

Friday, May 2nd, 2014

The modern miracle of electro-mechanical air conditioning started in the early 20th century when Willis Haviland Carrier introduced an invention to cool down and control humidity in a paper plant. Since the mid-1950s, air conditioners have become accepted standard equipment in homes, as common as stoves, refrigerators, and televisions.

However, homeowners often know little about how air conditioners operate: they usually have a firmer grasp on the mysteries of a more recent invention, the microwave oven. Here are three misunderstanding about air conditioning systems that we often encounter in our work.

Although a little knowledge about ACs is helpful, you should always turn to professionals when it’s time for installation, repairs, or maintenance. DB Heating & Cooling can provide the assistance you need to get the most out of your home’s air conditioning in Westwood, NJ. There are no AC misunderstandings among our trained staff!

#1. “Air conditioners create cool air”

Although an AC fan blows out cool air, it is inaccurate to say that the system creates cold air the same way that a furnace creates hot air. In the case of a furnace, the burning of fuel generates heat, which is then transferred to the air. But an air conditioner does not burn any fuel. What it does instead is use electricity to run mechanical components that move heat from one location to another. When an air conditioner removes heat from the indoor air, the air feels cooler to us.

#2. “Turning the thermostat down lower will cool a space faster”

It’s tempting to turn an air conditioner’s thermostat down to the lowest temperature possible (60°F for most systems) believing that the air conditioner will ramp up the speed that it blasts out cold air. However, lowering the thermostat isn’t like pressing your foot against an accelerator pedal. A thermostat is simply a switch: it turns the AC’s compressor on until reaching the set temperature. The rate of cooling does not change. Putting the temperature at its lowest setting will simply keep the compressor running for a longer period. This is a leading cause of energy waste in homes; it is far more efficient to keep the thermostat set at a comfortable higher temperature.

#3. “You’ll have better AC efficiency leaving the system running when you aren’t home”

This myth comes from a belief that it requires more energy to turn a system on and off than to leave it running steadily. While it’s true that an air conditioner uses the most amount of power when it starts up, it is far more wasteful to force the air conditioner’s compressor—the component that drains the most energy—to run for 8 hours replacing cool air with cool air. A much better plan is to use a programmable thermostat to turn the AC on a half hour before you return home so you arrive to a cool house.
