Why is my AC freezing?

First let’s figure out if your AC is actually frozen. You may not always be able to tell if your AC is freezing up from the outside. One of the first signs it’s freezing up you will notice warm air is blowing out from the vents. The first thing you should do in this situation is cut your AC unit off so it can begin to thaw. Below we will discuss the top 3 causes! Air conditioners freezing up is a common issue that can have many possible causes though so we always recommend to call a professional.

Blocked Air Flow

Air conditioners need to have a constant flow of air so first you need to be sure your air filters aren’t dirty and clogged it can restrict the air flow in your house. Your homes filters should be changed every 30 to 90 days depending on type and factors check out our filter video for more information on that! If this is the problem you will still need to turn the system off to let it thaw this can take a few hours to half a day depending how frozen it is. After thawed simply change or clean filters and restart system. If this doesn’t fix the issue keep reading for more possible causes!

Refrigerant Leak

If your system has a refrigerant leak this will causes a drop in pressure, allowing the refrigerant to expand too much and become too cold. Refrigerant is also an essential part in ensuring a regulated temperature throughout your machine. A too-low level of refrigerant is also known to cause freezing up. We find the most common place ACs tend to leak is their Evaporator coils but it can be anything from a suction line to a major component. If this is the case you would need to have a professional out to do a leak search.

Dirty Coils
The system pulls the water out of the air, which makes condensation that builds up on the coils. Typically this isn’t a problem because the condensation droplets fall off the coils into the drip pan. But if the drip pan is overflowing, the coils can become waterlogged and freeze. Dirty coils can cause freezing because the layer of dirt on top of the coils can prevent them from absorbing the water fast enough. Bi-annual checkups from your local HVAC professional can keep your AC’s coils clean.

A freezing AC is a very common, frustrating problem that many homeowners face. However most of the problems causing a frozen AC are preventable with some regular maintenance. Hiring a professional HVAC service and taking advantage of Maintenance Service Plans, help you keep your AC in tip-top shape, will save you money on your energy bill and help keep your AC unit running for years and years.

Quick Tips to stay cooler

Quick Tips to Stay Cooler

14 SEER vs 16 SEER

amana blog pic

If you’ve looked into replacing your AC you may have heard the options of 14 SEER or 16 SEER units we wanted to do a quick blog just explaining what that is and what some of the key differences are. SEER stands for Seasonal Energy Efficiency Ratio. The SEER rating of an HVAC unit is determined by dividing the total amount of cooling it produces in a season by the total amount of electricity needed for that cooling. The higher the rating, the more energy efficient the unit is.

If you’re replacing an older, less-efficient HVAC, you will see a significant decrease in your energy bills with even a 14 SEER unit because even the 14 SEER tend to me more efficient then a lot of the older units made 15+ years ago but now that we understand what SEER means of course the 16 SEER is going to be even more efficient! The amount of money you will save with the 16 SEER versus the 14 SEER would depend on the size of your home as well as how much cooling you do each year. On average we find a 16 SEER unit uses about 15% less energy to produce the same amount of cooling as the 14 SEER so if you think about that long term of course depending on those other factors there is defiantly some money saving potential. Besides the money saving side of it there are more potential pros for going with the higher efficiency system. Typically a 16 SEER unit will include a two stage compressor which will help the unit adapt to conditions in your home where as with the one stage its ether running full speed or not at all. This keeps the temperature in your home more consistent in turn improving your comfort. Depending on the manufacture of the equipment and company installing it there could be benefits with the warranty as well. Evergreen Heating & Air with Amana offers a 10 year labor warranty with our 16 SEER units. This means for 10 years from your install if you had any issues not only would your parts be covered but the labor as well which can be a huge savings in itself.

If you would like more information of the pros and cons for each give us a call and one of our comfort care experts can come out and give you a quote and discuss what would be best for your home.

Benefits of Smart Homes


Smart Homes are the future! You can virtually control your whole home from your phone or virtual assistant. In this blog, we will talk about why you may want to consider turning your own house into a smart home. The benefits are limitless and we will discuss some of the main ones.

Safety & Peace of mind
This is one of the biggest features for me personally. First the obvious reason with doorbell cameras you can monitor and even communicate with anyone at your door from your phone or smart device. It’s very simple and some of the cameras like the hello doorbell can even detect movement so even if an intruder doesn’t ring the doorbell or knock on the door your phone will alert you and show you live feed from your front door. Smart home devices such as Alexa can play into safety as well I know it has for our family. My grandfather has Parkinson’s disease and at this point is unable to use his phone. Although someone is typically with him most of the time there is times for short periods he is home alone. What if there was an emergency? He has no way to call anyone. That’s where Alexa or google home comes into play. We set these devices up throughout the house and he is able to use them to call my grandmother if he needs something and more importantly get help in emergency situations. Therefore in case of an emergency even if he has fallen and cannot get up all he has to say is Alexa call 911 and can communicate through her from anywhere in his home.

This is another key benefit and I don’t think everyone quite realizes how much easier this can make things on a daily basis until you have one. Take it from my personal experience having Alexa synced to all my home devices I can control everything from Alexa or my phone. For example you just got in bed and realized you left the kitchen light on. All you have to do is say Alexa turn my kitchen light off and it’s done. Another great thing I use it for is scheduling things throughout my day and helping me remember things. I’m a mother so I have what I call “mom brain” where I forget everything! I simply say “Hey Alexa remind me I need to pick up butter for dinner tomorrow.” I could go on forever about how much this helps in my everyday life.

Energy Savings
The fact that you can control all of the things in your home from your phone is going to help save you money and ensure your home is running efficiency. The NEST smart thermostat is a really good one for saving on your electric bill each month. Of course the fact that you can control it from anywhere is going to help you save electric when your not home but it does so much more than that. It collects, analyzes, and presents data on home heating and cooling based off your home and needs. Nest’s will also expose you to further opportunities to save energy. If you see the Green Leaf on your thermostat, you can press it for information on ways to save energy.  Most smart home products are very efficient including bulbs, appliances, etc.

Again these are just a few of the many benefits. One last thing I wanted to mention anyone can use these devices! As I mentioned earlier my grandfather uses it we’ve posted videos of my 5 year old using it so please don’t let that hold you back. These products were built to be easy and convenient for everyone!

Do I need to have dryer vents cleaned?

We find dryer vent cleanings are not done as often as they should be and wanted to give a little more information and what the purpose of it is. As we know our dryer uses warm air to dry clothes therefore if your dryer vent to the outside becomes blocked the warm air will not be able to force moisture like it is supposed to do in order to work properly. The result will be trapped moisture that takes more heat energy to evaporate and can actually cause fires and other issues. We recommend having your dyer vent professionally cleaned at least once per year. There is also a few signs you can watch for that may mean your dryer vent is clogged.
• Clothing are very hot to the touch
• Taking longer to dry clothes
• Burning Smell

Another great way to stay on top of dryer vent cleaning is a product we install called LintAlert. It actually hooks up to your dryer and will notify you on your phone if it is clogged. This is a great safety measure to ensure peace of mind. For more information on this or to get a dryer vent cleaning please give us a call today. You can also now book online from our website!

Electric vs Gas Heat

Considering replacing your furnace? There are so many choices when it comes to replacing your HVAC units but today we are going to talk about the differences between gas & electric which will help you make an informed decision on which is best for your home.

Gas Furnace
Gas furnaces operate at up to 98 percent efficiency. Natural gas tends to be less expensive then electric overall, but they are much larger than an electric furnace & require ventilation equipment. Therefore initial cost is typically a little higher. Another concern with gas is CO2 leaks which can be dangerous. If you receive regular maintenance & have CO2 detectors this isn’t a huge issue.
Electric Heat pump
Electric heating is safer than gas and does not produce any gases during the heating process. They also tend to run quieter than a gas furnace. However, as mentioned above electrical heating systems are not as efficient or affordable as the gas therefore your monthly investment will be a little higher.

Both systems would be a great choice it really just depends on your location and what work best for your individual needs. If you’re still not sure when you’re ready for a new furnace, Evergreen Heating & Air can guide you through the selection process. We can help you choose the right furnace size and compare energy efficient features that can improve comfort & efficiency.

80% vs 90% Gas Furnace

Installing a new gas furnace is not a simple or cheap endeavor. They say Knowledge is power but it can also ensure you are getting the right furnace for the correct application.
When it comes to a gas furnace you have several options to choose from. Depending on your specific set of circumstances one type of gas furnace may benefit you more than the others.

You have two basic types of Gas Furnaces: 80% and 90%

The differences were explained to me a long time ago in a way I found very simple to understand. For every hard earned dollar you spend heating your home with a 80% efficient gas furnace basically 20 cents goes up and out the flue pipe while the other 80 cents is used to actually heat your home.
A 96% efficient gas furnace allows you to utilize 96 cents of every dollar to heat your home where only 6 cents is wasted up and out the flue pipe.

Why would I ever install anything but a 96% gas furnace in my home??????????????????
The one thing you have to know about a 96% efficient gas furnace is that it produces water in the process of making it so efficient. In the winter time when the gas furnace runs the water being drained from the unit can possibly freeze up depending on where the furnace is located (example in your attic) or where the water is being discharged to example outside of your home again where it may be well below freezing.
The other major factor is the cost difference between an 80% gas furnace and one that is 96% efficient. The more efficient the more the cost of the product. There are more parts and technology involved in the higher efficiency furnaces than in the 80% version. Thus the cost difference between the two can be quite different.

My Suggestions
If you live in a two story home I would suggest the main floor of the home be served by a higher efficient gas furnace while the upstairs unit could be an 80% gas furnace. The reasoning behind this is based off of the principle of hot air rises. The air from downstairs will travel up stairs assisting the heat requirements. This typically means the downstairs unit will run more and consume more fuel where as the upstairs will not run as much. If you have a single story home with just one unit I would strongly suggest paying the difference and upgrading to the 96% gas furnace as you will reap the benefits of consuming less fuel monthly.furnace clipart

5 signs its time to upgrade your heating system

With winter in the near future it’s a great time to evaluate your current system and figure out if it’s time for an upgrade. Of course you can just wait until it stops working but planning ahead can give you time to explore and compare your options as well as ensure you won’t have to go without heat. Here’s 5 signs it may be time to consider changing out your hold system.

-Age: Most systems typically last somewhere around 20 years if your units 15 years or older it may be time to start exploring new systems.

-Electric Bill: Furnace efficiency can decline as the unit ages and is not running a full capacity. If you start to notice a rise in electric for no reason that could be the culprit.
-Running Continually: A unit that turns on and off continuously may be too large for your home or in need of repair.

Multiple Repairs: Frequent, costly repairs are typically a sign of more to come. Once multiple parts and components start failing others will start to as well. If you’re facing a repair bill of $500 or more, and the unit is more than 12 years old, it may be time to consider upgrading to a new unit.

Air-quality issues: If you’re finding excessive amounts of dust or soot or rust particles these are signs that your furnace has lost its ability to effectively clean and humidify the air in your home.

Getting ready for Fall

With Fall approaching we wanted to share some tips to help ease your home & air conditioning into the season.

-Check & Change filters
Regularly checking and replacing HVAC filters is one of the most important things you can do to ensure the systems longevity and prevent breakdowns.

-Use Fans and Open Windows
Now that it is starting to cool down you can turn the air conditioning unit to a lower setting. Start using your ceiling fans and opening windows. Not only does it take some of the burden off of your air conditioner, it allows your house to air out and stay fresh.

-Schedule Maintenance
Though you may not think it, your HVAC services need preventative maintenance at least twice every year. This is the perfect time to call your local HVAC Company and have your system inspected & maintained.

-Clean your outdoor unit
Check your outdoor unit for any debris or damage.

Going Ductless

We have mentioned mini splits in the past when considering adding air to a basement or bonus room, but did you know your whole home could be ductless? Ductless mini splits are small air source heat pumps that are specifically designed to cool and heat individual zones in your home. As with anything it has its pro’s and con’s but if it’s worth checking out!
– – Save Money -With ductless you have a thermostat for each room or zone therefore you only have to use air in the areas you occupy which in turn will save you money in electric.
– Comfort for the whole family – With each room having its own thermostat everyone can heat or cool their room to fit their own needs.
– Ductless Systems are more efficient – In most homes you are losing so much energy just from the duct work. By removing the duct it is already more efficient but added bonus ductless splits have a variable speed compressor which basically will speed and slow down based on your homes needs instead of shutting off and on like a typical system.
– Compact – Ductless splits are much smaller than a typical unit & as we’ve mentioned there is no duct or any additional equipment needed. They would be the perfect options for homes with limited space.
-Up-Front Cost- Ductless systems do typically have a slightly higher up-front cost, though this can be easily saved with the energy savings over the life of the system.
– Heating- Though ductless systems do provide heating, heating capacity is limited to certain climate zones. For those in extremely cold climates, you may need a fuel-based backup if you want ductless heat, although some newer models can handle the load even when temps fall below zero.
– Increased Maintenance- To maintain your system, you’ll have to wash or change each unit’s filter monthly (more often if you smoke or have pets). Ductless fans cannot handle debris as well as a typical system. We also recommend

Why is my AC not cutting on?

blog image

Is your AC not coming on? Check out a few possible causes and solutions below. If your still having trouble with it call your local HVAC pros to help!

  • Check Your Air Filters. We find this to be a common issue with having issues with your AC. Depending on your home and filter type you should change these every 30 to 90 days. When dust and dirt build up it is basically suffocating your system, and causing it to go into self-preservation mode and turn off.

• Look for a Blown Fuse/Tripped Circuit Breaker. If your unit has no power to it this could be the issue. Check the unit itself as well as the main circuit breaker.
• Make Sure the Drain Pan & Lines Aren’t Clogged. When your AC system runs, it creates condensation that runs out of your home via a drain line. If the drain pan is full, and/or this line becomes clogged, it will trigger a safety switch, turning off your system. Unclogging with a wet/dry vac or pipe snake and clearing the blockage could easily solve the problem. If it still appears to be clogged call your local HVAC Company.
• Icy Buildup. If you see any ice buildup on your system components, let it thaw before you try to turn the unit on. The bad news: This can take up to 24-hours. If the coil is clogged by dirt, blocking airflow, it will cause the temperature to drop and freeze up, preventing your system from running. Low refrigerant and improper fan operation can also cause this issue.
