Central Air HVAC System VS Ductless Mini-Splits: Pros & Cons

Heating, ventilation, and air conditioning is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. “Refrigeration” is sometimes added to the field’s abbreviation as HVAC& R or HVACR, or “ventilation” is dropped, as in HACR .

HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities medium to large industrial and office buildings such as skyscrapers and hospitals vehicles such as cars, trains, airplanes, ships and submarines and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.

Types Of Central Air Conditioners

A central air conditioner is either a split-system unit or a packaged unit.

In a split-system central air conditioner, an outdoor cabinet contains the outdoor heat exchanger, fan, and compressor, and an indoor cabinet contains the indoor heat exchanger and blower. In many split-system air conditioners, the indoor cabinet may contain the a furnace or the indoor heat exchanger of a heat pump. If your home already has a furnace but no air conditioner, a split-system may be the most economical central air conditioner to install.

In a packaged central air conditioner, the heat exchangers, compressor, fan, and blower are all located in one cabinet, which usually is placed on a roof or on a concrete slab next to the house’s foundation. This type of air conditioner also is used in small commercial buildings. The supply and return ducts come from indoors through the home’s exterior wall or roof to connect with the packaged air conditioner. Packaged air conditioners often include electric heating coils or a natural gas furnace. This combination of air conditioner and central heater eliminates the need for a separate furnace.

Determine Your Heating And Cooling Needs

Do you live in a place where the temperature outside gets close to freezing? If yes, consider investing in a furnace to provide hot, dry heat quickly. Does the temperature where you live stay consistent and mild most of the year? If so, a heat pump could provide the heating and cooling you need all year long. Assess your HVAC needs based on your geographic region, yearly temperature patterns, and home size to ensure youre installing the right device.

How Do I Know If My Ac Unit Is Of Good Quality

Its important to ensure quality and performance for years to come when youre installing a new AC unit. During the installation of your central air unit, ask yourself these questions:

  • Is the unit sized correctly? Pros should be measuring your home and doing load calculations to ensure the equipment is the right size for your home for optimal performance.

  • Is the duct system right for the AC unit? Ducts that are damaged, leaking, or missing in spots will affect performance. Your local AC repair pro will repair ducts and install more if needed for everything to work seamlessly.

  • How is the airflow? If the airflow isn’t just right, you could see an increase in your utility bill or experience hot spots in certain rooms. A contractor can measure the volume of air reaching the various spaces in your home and adjust ducts and vents for the most optimal airflow.

Clear Your Schedule For Installation

Central Air Conditioning

Most new HVAC devices take a few hours to a day to install, and its important that youre home for the process in case your technician has any questions for you. In some cases, such as having a furnace installed, installation could take multiple days because furnaces need gas sources. If you dont have one on your property, your technician will need to arrange for one.

Customer Reviews

I have my Air Conditioning installed by this company, the technician so nice , I was so happy for what they done for me!

Great service from Constant Home Comfort for my house foam insulation in July 2018 , temperature in my house feels comfortable after they have done the job, highly recommended !

To Cary and his team I would love to recommend your company to all my friends, the speed in which you came to replace our furnace is amazing, although I was told by the installers I called there are no rebates, you have been able to get me the rebates and lower my cost significantly.

I had an excellent experience with Constant Home Comfort. From the first phone call to constant home comfort, to the sales appointment all the way until the end of the installation process, i was completely impressed. Not only professionally, but friendliness and courtesy, which is very important to me. I have had bad experiences with HVAC companies before, but felt secure after the first phone call. I had replaced my furnace and a/c unit and Constant Home Comfort was able to save me more money than I initially thought, and they handled the paperwork for the rebates for me made the process SO much less of a hassle on my end. Thanks guys!

Installation And Location Of Air Conditioners

If your air conditioner is installed correctly, or if major installation problems are found and fixed, it should perform efficiently for years with only minor routine maintenance. However, many air conditioners are not installed correctly. As an unfortunate result, modern energy-efficient air conditioners can perform almost as poorly as older inefficient models.

When installing a new central air conditioning system, be sure that your contractor:

  • Allows adequate indoor space for the installation, maintenance, and repair of the new system
  • Uses a duct-sizing methodology such as the Air Conditioning Contractors of America Manual D
  • Ensures there are enough supply registers to deliver cool air and enough return air registers to carry warm house air back to the air conditioner
  • Installs duct work within the conditioned space, not in the attic, wherever possible
  • Seals all ducts with duct mastic and heavily insulates ducts
  • Locates the condensing unit where its noise will not keep you or your neighbors awake at night, if possible
  • Locates the condensing unit where no nearby objects will block airflow to it
  • Verifies that the newly installed air conditioner has the exact refrigerant charge and airflow rate specified by the manufacturer
  • Locates the thermostat away from heat sources, such as windows or supply registers.

Central Air Conditioner By Seer Rating

How to Install Central Air Conditioning

SEER stands for seasonal energy efficiency ratio, and the SEER rating of an AC system is particularly relevant if you live in a climate where the temperature changes drastically. SEER is calculated by determining the cooling output during the winter season divided by its electric input. The higher the rating, the more efficient it’ll be. Since 2006, the U.S. Department of Energy has required new central ACs to have a minimum SEER rating of 13. According to the U.S. Energy Information Administration, this will be increased to 14 in the northern U.S. and 15 in the southern U.S. by 2023.

The price to install a 14 SEER AC unit is between $3,000 and $6,000. The higher the SEER rating is on your AC unit, the more energy-efficient it’ll be. A 16 SEER AC runs from $3,700 to $9,000 to install. At the time of publication, federal tax credits for residential energy-efficient equipment expired on December 31, 2021, but check the Energy Star website for updates on whether any extension or renewal of these credits gets approved by Congress.

Demand Controlled Kitchen Ventilation

How to Maintain Your Central Air Conditioning Unit

Demand controlled kitchen ventilation is a building controls approach to controlling the volume of kitchen exhaust and supply air in response to the actual cooking loads in a commercial kitchen. Traditional commercial kitchen ventilation systems operate at 100% fan speed independent of the volume of cooking activity and DCKV technology changes that to provide significant fan energy and conditioned air savings. By deploying smart sensing technology, both the exhaust and supply fans can be controlled to capitalize on the affinity laws for motor energy savings, reduce makeup air heating and cooling energy, increasing safety, and reducing ambient kitchen noise levels.

Central Air Conditioner By Size

Pay attention to the square footage recommendations listed for each air conditioning unit youre considering. The general rule is that every 500 or 600 square feet require 1 ton of cooling power. However, this calculation can vary.

You can also estimate your overall price based on the British Thermal Unit capacity, which measures how many BTUs per hour the AC unit can add or remove from the air. You’ll need about 18 BTU capacity per square foot, but anywhere from 14 to 26 BTU capacity per square foot is acceptable.

Air Conditioner Size in Tons Capacity
48,000 $4,200 $6,200

The rule of thumb is that the bigger the house, the more cooling power is needed. But too big of a system isn’t good either because the central air system will cycle on and off all the time, which will waste energy and give off a loud, disruptive noise. On the opposite side of the spectrum, a too-small system will work overtime and cool your house inefficiently. Be sure to consult an AC pro to get the most accurate estimate for this project.
