Air Conditioning Tips for Your Vacation Rental

If you own a vacation rental, you want your guests to feel at home while at the same time not causing too much wear and tear on your property. One thing you can manage more than you might realize is your AC unit. Here are three tips to keep your residential air conditioning unit in your vacation home working well all summer long for guests to enjoy.

1. Empower Your Guests

There is never too much information that you can share with guests when it comes to maintaining your home and appliances. Leaving out the thermostat manual, notes on quirks, reminders, and suggestions are all good ideas. This way your guests will be less likely to accidentally break your AC unit or need to call in for emergency maintenance.

2. Have Your AC Unit Serviced Yearly

If you can keep your vacation rentals AC unit in working condition, this will be less likely to break down at inopportune times when guests are staying at your vacation home. Having your air conditioning unit serviced yearly can help, as well as periodically switching out filters and looking for inefficiencies throughout the year.

3. Remote Thermostat Control

Even if guests do a great job packing up after a trip, there is a chance they will leave the AC on. If you aren't having your place cleaned for a few days, this can be a waste of energy. If you can control your thermostat remotely, you can cool your home down before guest arrive and shut this off after check-out.

Offering up air conditioning in your vacation home can be an appealing perk for guests, but you might be worried this end cost you more than you bargained for. If you can take preventative measures with AC maintenance and management, you and your guests will both be happy. If you are having an issue with your current AC unit, contact us for help with servicing and troubleshooting.

The Difference Between Traditional And VRF Air Conditioning

Many people fail to appreciate all of the incredible innovations that have taken place in the air conditioning world in recent decades. Unfortunately, this often means that they fail to take advantage of efficiency boosting new technologies. If you would like to learn more about the options available today, read on. Here you will find a useful comparison between traditional systems and what are known as variable refrigerant flow air conditioning systems.


On the surface, variable refrigerant flow systems--often referred to as VRF systems for short--function much like conventional air conditioners. Both systems utilize refrigerant filled coils to cool down the air in your home. Likewise, the two types both utilize a condenser unit to change the heated refrigerant from a gaseous back to a liquid state. This condenser unit is generally located in the yard outside your home.


A conventional air conditioning system operates using just a single fan coil unit. This is the coil through which the condensed refrigerant flows, thus cooling down the air around it. A blower system then distributes this cooled air through the HVAC duct system in your home. Unfortunately, this often leads to inefficiency issues, whether because rooms are being cooled even when not in use, or because the air is not evenly distributed to all of the roofs.

A VRF system manages to avoid both of these pitfalls. It does so by incorporating multiple fan coils. Generally, several such fan coils are located here and there throughout your house. This allows you to manually--or even automatically, by programming your thermostat--alter the volume of refrigerant being sent to a particular fan coil. As a result, you are able to precisely tailor the amount of cooling each different zone of your house receives. This allows you to maximize cooling power, while avoiding spending more to heat unused portions of your home.

If you would like to learn more about how a VRF system can benefit you, be sure to contact the pros at Green Leaf A/C and Heating.

Understanding Two Key Components Of A Central Air Conditioning System

Knowing when and where an air conditioner is in need of maintenance can be a tricky thing for many homeowners. Unfortunately, this often leads to breakdowns and other expensive problems. If you would like to brush up your understanding of central air conditioning components, read on. This article will discuss two of the most important parts of your system.

The Condenser

The condenser is that large cube or cylinder sitting somewhere along the outside edge of your home. To understand its role, it helps to first realize how an air conditioner works. The basic idea is that refrigerant is used to cool warm air, which is then circulated through your home. In the process of accomplishing this cooling, however, the refrigerant turns from a liquid to a gas. In order to continue cooling air, it must next be turned back into a liquid. That, in a nutshell, is the condenser's job: condensing the refrigerant inside of the system from a gaseous to a liquid state.

The Evaporator Coil

Unlike the condenser, the evaporator coil is located inside of your home. It is housed in a special metal box known as the plenum, which itself generally sits atop the furnace. The job of the evaporator coil is to perform the actual cooling of air. Liquid refrigerant is pumped from the condenser to the evaporator coil. As the refrigerant courses through this coiled metal tube, it absorbs heat from the warm air around it. The evaporator coil is located in close proximity to the blower motor which distributes air through your duct system, meaning as air is cooled it can rapidly be sent outward into your home.

2 Good Reasons To Avoid Buying An Oversized Air Conditioner

When it comes to central air conditioning, many people make the mistake of thinking that it's wise to invest in the most powerful AC available. Unfortunately, installing an oversized air conditioner can actually end up having a deleterious effect--not only on the comfort of your home, but also on its air quality. If you would like to learn more about why you should only install a properly sized residential air conditioner, read on. This article will discuss two shortcomings posed by oversized units.

Inconsistent Temperatures From Room To Room

An oversized AC's abundance of power will almost always end up working against it. That's because all that excess power will lead to the problem known as short cycling. This simply refers to the fact that, since the air conditioner is able to generate such a large volume of cool air so quickly, it will only have to run for a short time before turning off again. 

On the surface this may seem like a good thing. But short cycling often leads to improperly cooled rooms. The issue is that there simply won't be enough time for the rooms farthest from your air conditioner's blower to receive an appropriate amount of air. Thus they will remain at a significantly warmed temperature. The rooms located closest to the AC, on the other hand, will tend to be uncomfortably frigid. 

Decreased Indoor Air Quality

Short cycle times affect more than just the temperature inside of your home. It also leads to an increase in the number of pollutants--everything from dust, to pollen, to pet dander--in your home's air. That's because, thanks to the short cycling, there isn't time for your system to properly circulate your home's air through its filtration device.

Signs You Need a Second Opinion on a Major Furnace Repair This Winter

Winter is the hardest season to get through without a climate control system. If you asked a heating and air conditioning company to come out and repair your unit, but have a nagging feeling that something isn't right, consider a free second opinion from a reputable company. Whether you have small children or older relatives living in the home, it's important to have a working furnace during these cold months. What are the signs you might need a second opinion on a furnace repair?

It is not blowing hot air

A furnace should always blow hot air that is well over 100 degrees Fahrenheit. If you notice lukewarm or cold air coming out of the vents, you are definitely in need of furnace repair. If a company ignores the temperature of your home, it's a red flag.

It comes on but turns off

This might be a sign of electrical issues, or a malfunction in the circuit board or thermostat. Seek a free second opinion on a furnace repair if your unit comes on and off sporadically, but you aren't hearing a clear answer on the problem.

It makes strange noises

If you notice a banging noise coming from the furnace, this might indicate a loose or unbalanced blower, have this fixed immediately to avoid it breaking. An A/C and heating company will not ignore unusual sounds coming from your unit.

You notice an odd smell

Have a professional inspect your system if you notice any new smells originating from the furnace, especially rotten egg-like smells, which could mean you have a gas leak. If a professional refuses to address the problem, seek that second opinion.

Higher than normal utility bills

If your electric or gas bill is higher than it normally is, this is a symptom of an older furnace, and it means it is becoming less efficient.

Green Leaf A/C and Heating provides free second opinions on all furnace repairs. We are a  trusted name in the business, serving the heating and air conditioning needs of people in the greater Austin, TX area. Having problems with your furnace this winter?
