How To Select The Correct Thermostat For Your AC Unit

Most ducted reverse cycle air conditioner buyers want to use a temperature control system with the AC device. Different systems are available for this purpose. Information about all these options has been provided below.

The Basic Controller

When you buy a reverse cycle air conditioning system, it will come with a built-in controller with a thermostat to read the AC temperature. The unit reads the temperature from the controller or airbox of the AC. The temperature inside the return air box may not represent the room temperature accurately. The room may be cold, but the air that comes back to the return air box after recirculating may have become warm when it reaches the box. It means the air-conditioning system will keep running. For example, the controller may have been set at 22 degrees, but after the air has reached the return air box, its temperature may have reached 30 degrees. It causes the AC system to keep running. What it means is that your air conditioner will keep running even when people inside the room are feeling cold. This problem can be solved in two ways. The first option is to increase the temperature of the controller. This way it is forced to cycle off faster. Keep in mind that the controller temperature setting is generally not precise. It is set on a scale. For example, if you set the temperature to 22 degrees, it may not cool the room up to 22 degrees. Many people use the second option to place a fixed constant close to the return air grille. As its name suggests, the setup is designed to remain always on. It lets the conditioned air go back to the unit’s return air box, helping the system cycle off easily. In such a case, if you are using the system only for the bedrooms that are further away from the return air box, the air coming from the rooms will overheat before returning to the return air box. The fixed constant bleed air into the grille directly, making the system cycle off. It reduces the running cost of the AC system as well.

VAV AC Controller

Variable Air Volume unit for the AC is another controller system for controlling the temperature of AC. The zone motors of the ducted reverse cycle AC system handle the temperature control process. In this case, a zone refers to a set of blades. When air is not needed for a room, the blades close the ductwork. For example, if the bedroom AC unit is turned off, the blades close the air gateway and restrict the airflow to the ductwork and then to the bedroom. Similarly, the blades will open when you need air. It allows the air to pass through the diffuser and reach the room. A VAV system works differently. In place of the blades closing or opening, they constantly adjust the opening percentage as required. The adjustment controls the airflow going into the room. It helps control the room temperature. For example, when a room’s temperature is about 30 degrees and the VAV controller in the room has been set at 22 degrees, the cool air rushes in to cool the interior. Once the room temperature reaches about 22 degrees, the blades start closing to stop the airflow and maintain that level. When the interior temperature increases and goes above 22 degrees, the adjustable blades open again, allowing more airflow to bring back the temperature to 22 degrees. This continuous process helps maintain the room temperature at the required level. A VAV controller is the most basic AC temperature control system. It is an economical option to control the temperature of a few rooms. It is different from the VRV AC system with several walls or head units that run from one large outdoor compressor.

Complete AC Temperature Control

A fully ducted AC temperature control system works similarly to a VAV system. Each room has its controller, which reads the temperature and then adjusts the closing and opening of the blades to cool or heat the room. A full temperature control system controls the temperature of the whole house and not only a few rooms. It provides the best comfort for everyone because each room’s temperature can be controlled individually to suit the requirements of the people in a room. It is affordable and economical to run compared to the standard systems because it helps save more energy. The system switches off when the room reaches the set temperature, allowing the AC to cycle off. The running cost comes down substantially with this efficient temperature control system.

The Reasons to Select a Temperature Controlled Air Conditioning System

The advantage of an AC temperature control system is that it allows every user to set the desired temperature. Everyone has a different temperature requirement based on various factors like age, body, and health. One temperature suitable for one person may not be comfortable for another person. Everyone wants to set the room temperature according to their needs and preferences. Some other factors also determine what temperature is best for a room. They include the heat load of devices and people present in the room, the clothes people wear, and the side of the house facing the sun. A temperature control system is designed to consider all these factors and adjust the room temperature accordingly. This simple and inexpensive system allows everyone to control the room temperature based on their cooling and heating needs. However, these systems are not designed to cool and heat at the same time. If the AC is set for cooling, it will only cool the interior. If you want to heat one room and cool another, the AC system cannot do so. You will need separate AC systems for different rooms for such a requirement. Consult a professional air conditioner consultant or technician before installing any air conditioning system at your place. The professional will audit your rooms and determine the best AC system according to your cooling and heating requirements.

Repairing or Replacing – The Importance of Updating

If replacing equipment is your only choice, be certain it is Energy Star compliant. It may appear to be a minor issue, but it is not.

We are all aware that aging impacts dependability, electronics, mechanics, and humans. Your old HVAC system may still be serviceable. Try it out and see how it goes. Calculate all of the related expenses, such as system longevity, system efficiency, and the age of the current unit, after getting an estimation of repair costs against replacement prices. Keep in mind that the older your cooling and heating equipment is, the more likely it is that you will be forced to review the choice on whether to fix or replace it.

Request that they put up a budget-friendly HVAC replacement plan for you. Then be sure that the package contains a modern, energy-efficient cooling system and some artistry warranty of excellence backs the installation.
How to Make an Informed Decision About Repairing or Replacing Your Air Conditioning System
Many factors must be considered when deciding whether or not to repair or replace an air conditioning unit. It’s crucial to keep these considerations in mind while making a selection. These guidelines may be applied to any heating and cooling system. Don’t hesitate to contact your HVAC vendor with any manufacturer-specific inquiries.

Air Conditioning Refrigerants

R-22 or R-410A; These are the two most common forms of air conditioning refrigerants in residential heat pumps and air conditioning condensing systems. But, because of the 1987 Montreal Protocol and the 1990 Clean Air Act Amendments, R-22 and other ozone-depleting compounds are being phased out. No chemical producers will be allowed to make R-22 for residential air conditioning service after January 1, 2020. At that moment, only recovered, recycled, and reclaimed R-22 will be accessible for servicing current air conditioning and heat pump units. Only reclaimed R-22 will be accessible to current A/C and Heat Pump units. Even though uncharged R-22 systems may be installed as a replacement or repair choice for a current older system, 13-SEER efficiency is the best available choice, and the R-22 might be more expensive than you could have imagined. If the choice is between substantial repairs for an R-22 system and switching to a new R-410A system, the new system is the better choice in most cases.

Seasonal Energy Efficiency Ration (SEER)

TIP! Evaluate the rated energy efficiency of a new HVAC system before purchasing one. Though the price may be relevant, the long-term benefits of a newly installed energy-efficient cooling system can amount to thousands of dollars in lower unit lifetime energy usage throughout its lifespan. You can’t afford to put off deciding on your HVAC system.

13-SEER is the lowest efficiency rating for central air conditioning units, as established by the United States Department of Energy and upgraded in January of 2006 to 15-SEER. Better performance and energy effectiveness are reflected in a higher star rating. When confronted with whether to repair or replace air conditioning in an old 10-SEER unit, ensure that the repair is inexpensive and straightforward, or otherwise replace it with something newer and more efficient.


Heat pump performance and efficiency are assessed by a domestic SEER scale, equal to that used on household central air conditioners, and a Heating Seasonal Performance Factor (HSPF). The HSPF of your current Arizona Heat Pump, which is also established and determined by the DOE, maybe just as crucial as your air conditioning, ac SEER rating. Using a hp is more cost-effective than using a fuel-based solution for heating. It is possible to save money on your winter heating expenses in Arizona by installing an efficient heat pump.

Yearly Fuel Use Efficiency (AFUE)

ASHRAE sets the specifications for your system’s AFUE, the American Society of Heating, Refrigeration, and Air Conditioning Engineers, to guarantee that your house is supplied with efficient HVAC equipment. ASHRAE requires manufacturers to develop heating and cooling systems with an AFUE of not less than 80 percent. However, conscientious air conditioning producers aim for 96 percent or above. So what exactly does the AFUE rating mean? The AFUE rating tells you how well your furnace uses the money you spend on energy in layman’s terms. So, a 90% AFUE rating indicates that ten cents of each dollar are being wasted.

Warranty Coverage From The Manufacturer

Maybe you’re wondering why someone would require a warranty on a product designed to last? Face the facts! Perfection is unattainable in this world. Even the most diligent attempts to create completely fault-free heating and cooling system come short. While purchasers mostly receive a winner, occasionally, they receive a lemon. Each major HVAC equipment manufacturer wants to produce the optimum product for the money invested, but they, too, are aware of Murphy’s Law’s problems. Compare the terms of the warranties on various products. Make a list of everything covered and how long that coverage is valid. When the option is available, consider purchasing an extended warranty.

Ensure that your HVAC installation company backs up its services with a limited lifetime artistry warranty as a follow-up measure.

Selecting An A/C Installation Team

The HVAC sector faces some of the most intense competition of any sector in the country. Inefficient cooling solutions often result from unauthorized installation companies offering low prices. Ensure your safety by hiring qualified air conditioning contractors Insist on seeing proof that a business is Bonded, Insured, and Licensed to operate on your property. Get references and verify them. Installing a new air conditioning system isn’t exactly cheap. Keep yourself from having to deal with any future headaches. Use a trusted vendor.
