Want to learn about the basics of cooling and air conditioning? Here are answers to some of your most asked questions.
How Are Central AC and Ductless Cooling Different?
Central air conditioning uses a single outdoor compressor that transfers cooled air through a network of ducts in a building, which is then pushed out of vents placed throughout the space.
Ductless cooling features an outdoor unit that pumps air through refrigerant lines into an indoor unit called an air handler. To cool an entire building with ductless, usually more than one unit is needed.
What Is the Best Type of Air Conditioning System?
Ductless air conditioning is the most energy-efficient kind of cooling on the market today.
That said, the needs of businesses and homeowners are widely varied. An experienced HVAC specialist can help you determine which cooling system will work best for your space.
How Can I Save On Cooling Costs?
You can save on cooling costs by setting the temperature on your air conditioning system a little bit higher than usual, or by opening windows and using fans instead of your AC when the weather is mild.
You can also save on air conditioning costs by sealing cracks around windows and doors, closing curtains to avoid letting the sun rays shine directly in, keeping your filters and vents clean, and making sure your ceiling fans are set counterclockwise.
How Do I Know If I Need My Air Conditioning System Serviced?
Your air conditioner should be serviced if it’s making odd noises, has a bad odor, is leaking, or is blowing warm air.
Instead of waiting for something to go wrong before having your air conditioner serviced, be proactive. You should have your air conditioner evaluated routinely for potential issues, particularly before the start of summer ensure it stays in working condition.
How Do I Select an Air Conditioner Technician?
Choose an air conditioning company that has a great reputation in your local area and offers superior service. Work with a provider who is willing to sit down and go over costs and benefits with you in-depth to make sure you understand what you’re getting.
Don’t hire technicians without a logo on their vehicle, who don’t have a website with an address, or don’t call you back when you leave a message. Make sure your provider has the appropriate certifications, insurance, and warranties needed to do the work right.
Why is my proposal/quote so much higher than the cost of the equipment I can buy online?
If you’re an online shopper, you might have researched the cost of buying a cooling system online, especially if you’re looking at ductless heating and cooling systems. Many of these systems look like they would be simple to install yourself, and you may question why the quoted installation price is so much higher.
Keep in mind that these systems are designed for a professional to install with the proper tools and equipment, and often don’t come with the accessories necessary to complete the job. Ductless systems require making a hole through your house to the outside for the wiring and hoses, which isn’t a simple job.
Additionally, labor costs need to be added, as will having an electrician hook up the wiring, permits for the construction, sales tax, engineering reports to make sure you buy the right unit for your home, overhead costs for the contractor, and a small profit.
Yes, you could save some money by buying and installing the system yourself, but most people do not have the expertise required to install a system properly, legally, or safely. Unless you’re an HVAC contractor yourself, we don’t recommend attempting it. But most importantly, don’t think the HVAC company is marking up the price to make a huge profit — there are many legitimate expenses involved in the job, and your contractor should be able to walk you through those expenses so you understand what you’re paying for.
