How Do Ductless ACs Work?

Sunday, April 3rd, 2022

In modern days, people are investing in ductless air conditioners to experience cool weather and comfort in their houses. The mini-split cooling system is popular for the unique cooling effect it gives a room, especially on a hot day. The system also works well when you need warmth in the room on a cold day. The ductless air conditioners tend to be multi-functional. If you live in Sutton, MA, and the surrounding areas be sure to contact Landry Mechanical Inc Plumbing HVAC & Electric, talk to our skilled technicians and get the best advice on mini splits and their workability. Our skilled technicians will also advise you on the best type and size for either commercial or home use.

What Are the Functions of Ductless Air Conditioners?

Understanding how ductless air conditioners or mini-splits work is an important step for everyone looking to install them in their homes or offices. The mini-split cooling system tends to work like the traditional air conditioner, but different factors differentiate the two. Like its name, the ductless air conditioner does not have ducts. The ductless air conditioner cools the room by absorbing the moisture and heat from the air as it discards it to the outside. This is different from how conventional air conditioners work. They use ducts to take the heat in and out of the room through the vent system and then distribute the cool air into the room.

Components of a Ductless Air Conditioner

To better understand how the mini-split air conditioners work, it is best if you get a glimpse of the different components that make them. The ductless air conditioner has three parts:

  • A condenser- A condenser is placed outside. It is responsible for taking the hot air from the room and dumping it outside, bringing in a cooling effect to the room.
  • The blower unit – This is the part of the ductless air conditioner placed in a room. Its primary function is to pull in the hot air from the room, absorb the moisture and heat, send it to the outside of the room to the condenser, and bring in the cold air, which makes the room have that cooling feeling.
  • The conduit-The ductless air conditioner’s last component is the conduit that connects the condenser and the blower unit, making it complete. It is the part that provides the electrical power to the ductless air conditioner, which is essential for its functionality.

Does a Ductless Air Conditioner Have Enough Cooling Power?

Now that you understand that the ductless air conditioner has different components, you might be wondering if they have enough cooling power. You may also be used to conventional air conditioners that you feel the mini-split cooling system may be too weak to help cool the hot air in your home or place of business. It is then safe to say that the mini-split’s workability is dependent on the size of your room. For the best results, a big room requires a big cooling system or a big mini-split while a small room requires a small cooling system.

Getting a small mini-split for a big room might require the cooling system to overwork while getting a large mini-split for a small room will leave the system underutilized. Therefore, it is important to get the right size and the most appropriate ductless conditioner for your room for great cooling effects and longer lifespan to the cooling system.

The ductless air conditioners come in different sizes, making it easy for you to identify the necessary BTU capacity. All you need to have is the right measurement of the room you intend to install the mini-split system.

  • A mini-split with 12,000 BTU works best for 400 to 650 square feet of rooms.
  • Those with 18,000 BTU work best for rooms measuring 600 to 1000 square feet.
  • A mini-split with 24,000 BTU works best for rooms measuring 1000 to 1300 square feet.

If it is hard for you to determine the ductless AC you need, you should consult our technicians at Landry Mechanical Inc Plumbing HVAC & Electric. The technicians will visit the room or rooms in question and according to their size, give advice on the most appropriate ductless AC size. With the right size, the ductless air conditioner tends to have enough cooling power, making it a great investment.

Benefits of a Ductless Air Conditioner

The use of the mini-split cooling system is continuously increasing, as many people find the equipment better than the traditional air conditioners. Using the mini-split cooling system tends to have many benefits. They include

  • The mini-split cooling system offers different functionality, including dehumidifying and purifying the air. It helps the user cut the costs of getting both air conditioners and air purifiers.
  • The mini-splits are affordable, especially if you are getting them for personal use in the house.
  • It is very easy to install a ductless air conditioner, and one does not need to have too much manpower to have them installed. You can have one technician come to your house and install it, unlike the big and complicated traditional AC that needs more manpower to install.
  • The mini-split does not require any ductwork. This means that adding the air conditioners in the different parts of the house is almost effortless.
  • The ductless air conditioners effectively save energy. They are believed to save energy by about 30% because they are ductless and do not experience duct leaks that lead to loss of energy.
  • The ductless air conditioner is multifunctional; it can either heat or cool the room. The multifunctional aspect of the mini-split makes it a critical piece of equipment in the household since the homeowner does not have to buy different systems for different functions.
  • The ductless air conditioner is flexible as it can be mounted anywhere, depending on the room’s configuration. You can mount the mini-split air conditioner on the floor, the wall, or the ceiling.

Investing in a Ductless Air Conditioner

Investing in a ductless air conditioner for your home or office is one of the best financial decisions you can make. The system not only saves you money on installation, but it also saves you money on utilities and its operations are quiet and smooth. Investing in a ductless air conditioner means that you will no longer be paying money for duct cleaning, duct inspections and even ductwork sealing. Eliminating the need for ductwork eradicates the possibility of having dust mites, bacteria, mold and viruses that normally find a haven in ductwork.

9 Elements of Assessing Your New Home’s Heating and Cooling System

Thursday, March 10th, 2022

Unless you’re an HVAC professional, chances are that you don’t know how to evaluate your new home’s heating and cooling system. This can put a damper on the excitement of moving into your new residence because you worry about the comfort system giving out suddenly. Consider these nine elements to evaluate your HVAC system’s condition and whether you will need to have it replaced.

1. Assess the System’s Life Expectancy

Start by comparing your system’s age to the expected service life of the constituent components when properly maintained. Forced air gas furnaces should last 15 to 20 years with central air conditioners serving about 10 to 15 years. If your system’s age is nearing these limits, you may want to start planning for a replacement.

The challenge is uncovering when your system was manufactured. For your furnace, you’ll want to look for the serial number, which will give you the date. You’ll either find this on the label attached to the back of the access panel or stamped on the circulating fan motor or blade. If you have to look at the motor, be sure to kill the power at the circuit breaker to prevent a possible injury.

Once you have the serial number, take the first four digits to learn when it was manufactured. The first two digits correlate to a week in the year, and the second two are the year that it was produced.

For your air conditioner, simply find the stamped nameplate attached to the housing on the outside condensing unit. The plate should have the date of manufacture included on it.

2. Evaluate Maintenance History

The service life is in part determined by how well the system has been maintained. You may not receive extensive maintenance records from the previous owner, but you can get a sense of how much attention the equipment received.

Start by turning the system off and removing the access panel. Look at how much dust and dirt has collected on the circulating fan. You can also pull out the furnace filter and check to see if it’s clogged. The more dirt collected on these areas, the less air will flow through the equipment, and the more strain it has experienced. This is a key indicator of system neglect and likely a shorter life expectancy.

3. Get a Professional Tune-up

An easy way to get an assessment of your system’s condition is to have a professional tune-up performed. Based on its internal condition, a trained technician will be able to easily tell if the system has been neglected. Further, they will test the system’s cycling to see if there is anything working less than optimally. Finally, the tune-up will give you an initial boost to your heating or cooling efficiency by ensuring that there isn’t unusual strain.

4. Consider Your Thermostat’s Condition

Given that it regulates when the equipment turns on and off, your thermostat is a critical part of your heating and cooling system. However, the thermostat could stop working as well as it ages because the temperature sensors become less sensitive. This is true whether you have an old mercury thermostat or the newer digital models.

In addition to becoming less sensitive, older models also have fewer functional options, particularly in programming capabilities. If your thermostat still uses a mercury switch or it doesn’t have a program function, it’s likely a signal that you have an older system. Most companies include a new thermostat when they install either a new air conditioner or furnace.

5. Assess Physical Condition

Next, look at the physical condition of your system, paying particular attention to signs of corrosion. Without digging too deep into the internal workings, you’d look for rust on the furnace or AC housing. Also, look for excessive moisture around your furnace even if you’re running the air conditioning. Finally, look to see if there’s discolored water or bits of metal on the drip pan under your furnace.

In your outdoor air conditioner unit, check for signs that it has been impacted by flying debris, including dents and cracks in the housing. If you can see the fins on your condensing coil, look to see if they’re bent flat, restricting the airflow through the coil.

6. Reevaluate Your Capacity Needs

Regardless of the age of your system, it’s important to make sure that its heating and cooling capacity matches the serviceable area. If it’s too small, your system will have long cycles, using extra energy and adding strain to the equipment. It’s common for the system size to become mismatched when renovations are completed that change the heating and cooling area, such as finishing a basement or attic or putting on a room addition.

For a quick review, you’ll need to calculate your heating and air conditioning separately. For your heating, multiply your square feet by 50, which will give you the minimum recommended BTU capacity. Multiply the square feet by 30 for your air conditioner. You can then compare this to the capacity of your current system.

7. Test Temperature Rise or Fall

If you have a probe thermometer, you can check the temperature of the air coming out of the vent. There isn’t a set temperature for the air, but it should rise for heat or fall for air conditioning. If your furnace is running properly, the air from your vents should have a rise of 45 to 70 degrees compared to the return air temperature. When your air conditioning is running, the fall should be about 20 degrees Fahrenheit. If either of these differences is less than they should be, your system needs some attention.

8. Listen for Strange Sounds

Your system should run nearly silently when it’s operating correctly. If it makes screeching, scraping, banging, hissing, gurgling, or buzzing sounds, there is a problem. These can range from minor issues like your ductwork flexing to major issues like a cracked heat exchanger. Whatever the problem, the longer you allow it to go unattended, the more likely it is that you’ll need substantial repairs or a system replacement.

9. Check Temperatures Throughout Your Home

When your system ages, it will stop pushing as much air through your home. This may be due in part to dust and dirt collecting throughout the system. It may also be due to parts like the circulating fan running less efficiently than intended.

Start this check by inspecting each of your vents to make sure they’re open and that each has at least a 2-inch clearance above and around it. Next, set up thermometers throughout the house, preferably one in each room. Lacking that, at least put one in the room nearest the air handler and at the farthest points away from the handler. The temperature should be within a degree or two. If it’s more than a few degrees different, you’ll need some work on your system.
