The Importance of maintaining your air conditioner
Having an air conditioning unit that works flawlessly is so convenient and comforting at the same time. There is no greater joy than walking into your cool home when it’s hot outside. This is a good reason why you might want to keep your air conditioner in top form, to keep you and your family comfortable. In addition to that, the importance of preventative maintenance for your air conditioners cannot be overlooked, as this will minimize the chances of a break down in the North Texas Summer heat. Another thing that cannot be underestimated, is the effect an AC system has on your utility bill when it needs to be maintained. A well-maintained heating and air conditioning system can save you hundreds of dollars each year on utility savings alone!
Air conditioner maintenance
Air conditioners need to be regularly maintained to keep running smoothly, for the same reason we change the oil in our cars every 3 thousand miles. You wouldn’t neglect that, now would you? We often forget our systems need maintenance, and just take for granted that it’s working when we need it, but your AC requires regular maintenance from a certified professional like Efficient Home Solutions to ensure it continues to work properly. There are so many systems out there that are poorly maintained, and many of those are ones we get calls about in the summer, when they’ve broken down!
What Can You Do if Your Air Conditioner Isn’t Cooling Properly?
If you get home late in the day and realize your home is a bit warmer than it should be, here’s a couple things you can do before calling Efficient Home Solutions.
- Check your air filter. Often a dirty filter could be the culprit. It’s best to check your filters every month, and change them as soon as there’s visibly dirt/dust accumulating. This simple monthly task can prolong the life if your HVAC system.
- Check to see if your unit is frozen up. If it is, there’s not much we can do until it thaws out. The best thing to do is turn your system to the “off” setting, and set your fan to “on”. Then give us a call.
If you haven’t had your air conditioner checked out for the Summer, give us a call today to schedule an appointment 972-235-2600. We’d hate to have your system break down when you need it the most!
Fall is here and winter will soon arrive. This means backyard barbecues, football, and best of all, saying goodbye to the scorching summer.
As homeowners, we understand the importance of having our air conditioning systems operating at their peak levels. If you have ever gone through even a day of summer heat with a broken air conditioner, you understand that maintenance is a necessity. You can always spot a home with no AC because every door and window is open and fans are spread out to provide air flow. You might also see the owner on the phone desperately trying to get a technician over to fix the unit. After one or two of those experiences, concerned homeowners will contract a reputable company and set up an inspection plan to ensure that they stay cool during the summers, not thinking much about winter.
Although mild compared to many parts of the world, North Texas winters can be cold with temperatures dropping below freezing. Most of us consider “winterizing” a foreign word which means stocking up on firewood for nights huddled around the fire pit. Those who are considered “prepared” make sure outdoor plumbing is insulated and that plants are covered. Many homeowners overlook the heating maintenance.
Here are a few reasons why an inspection and maintenance of the heating system is just as important as the periodic check-ups of the air conditioner.
Safety is the most important reason to do just about everything. While you may not imagine any major risks from a defective heater, there are some which could be life-threatening. Carbon monoxide, the odorless and tasteless gas that we’ve all heard about, can be generated from gas or oil burning heaters. Most people know it as a silent killer and all of us should take it seriously. Another risk is that an improperly running thermostat could result in overheating. Now being too hot is one effect and will certainly be uncomfortable, but it could also cause a fire which has even worse consequences.
Just like an air conditioner, a properly running heater operates safely and as efficient as possible resulting in overall less cost and more money saved. Not only will the equipment operate efficiently since heat loss will be reduced, it will run smoothly reducing unnecessary wear-and-tear and extending the operational life of the unit. Replacing an HVAC unit can cost more than $10,000. The cost of replacing your system makes the price of regular inspection and maintenance seem like pennies.
Finally, we’ll briefly discuss security. Keeping your heater operating at its peak level of efficiency is not going to provide the same security as your home monitoring service or the roving patrols by your neighborhood watch, rather than the feeling of knowing that you won’t be woken in the middle of the night looking for extra blankets and worrying that your loved ones are shivering and unable to keep warm. Regular check-ups and maintenance provides security in knowing that reliable warmth and comfort is provided for you and your family during the winter.Lucky for you, Efficient Home Solutions has appointments available for your Winter check-ups, so book now before it’s too late!

Are you making choices that seem harmless about your homes heating and cooling system, like closing or blocking supply air vents with furniture, or putting off replacing the filter? If so, you’re not alone. However, those decisions may be contributing to comfort issues around your home, like higher utility bills and a shorter life span for your HVAC system. Here are a few common mistakes homeowners inadvertently make, along with ways to avoid them.
Improper Thermostat Settings: Setting the thermostat to extremes throughout the year can lead to higher energy bills and uncomfortable living conditions while you wait for the HVAC system to bring the house back to the desired temperature. Homeowners sometime think they are saving money when they set the thermostat back 8 to 10 degrees while they are gone all day. Programmable thermostats make this an easy habit to adopt. However, the problem that gets created is that at 5 or 6PM here in North Texas, is when our attics are the hottest. Asking your system to lower the temperature 8 to 10 degrees at this time of day, causes it to have to run non-stop for the next 3 to 4hrs to cool not only the air, but all contents of your home, furniture, floors and walls. This run time is at the peak electrical use for your home because you also begin to cook dinner, watch TV, wash a load of clothes, and run the dishwasher. All these tasks add heat to the home and humidity. Raise the temp on your thermostat no more than 3 degrees when you leave for the day. This will shorten your spikes in electric consumption each evening, increase comfort, and prolong the life of your system.
TIP: The best way to save on utility bills year round is to add Insulation to your Attic and/or Crawlspace.
Closing Supply Vents or Blocking Return Vents: Closing vents to rarely used rooms can reduce energy bills, right? Wrong. Closed or blocked vents create negative pressure, which can lead to hot, dusty attic air being pulled in through cracks around unsealed ducts and/or positive pressure which could be pushing conditioned air into attics or crawlspaces rather than into your home. An unbalanced HVAC system works much harder to maintain your temperature settings and causes increased utility bills and shortens the life of your HVAC system.
Cluttered Condenser Area: The outdoor condenser unit is designed to release the heat the refrigerant just absorbed and removed from inside your home, however this is only possible if it is allowed to receive the proper airflow. Dirty coils due to shrubbery, weeds, dust or a nearby cottonwood tree, along with other items within a couple of feet from the HVAC system, can hinder proper air flow. To help achieve peak efficiency, clear away plant matter and other debris on a regular basis, and have a professional clean the condenser coils once a year.
Dirty Air Filters — Regularly changing your home’s air filters should be a top priority to maintain your systems efficiency, internal cleanliness and enjoy better indoor air quality. Filters that are caked with dirt impede airflow, causing the HVAC system to work harder to draw air. This can cause the system to freeze up. Homes without indoor pets can change filters every 90 days, homes with indoor pets should change filters every 30 days.
Irregular Maintenance — Similar to vehicles, home heating and cooling systems require regular preventive maintenance to keep them operating safely, effectively, and efficiently. Add a professional maintenance agreement to your calendar and schedule Fall and Spring check-ups in advance so you don’t forget. You’ll be glad you did when you receive your next utility bill!
So which insulation is better; Cellulose or blown-in-Fiberglass? You can do the research and decide for yourself or take a moment for us to share a recent client experience.
In 2015, we received a phone call from a distressed home owner. He and his family had suddenly developed severe respiratory problems, making it very difficult to breathe the air in their home. They weren’t exactly sure what specifically was causing the issues, but they did know it had something to do with recent work he had done in his attic to address a rodent issue.
Prior to calling us, they had hired a pest-control company to come out to resolve the rodent issue. The pest control company’s solution was to vacuum out the old insulation, block the access points and install new, “pest-repelling”, cellulose insulation in his attic.
What is cellulose insulation? Cellulose is ground up, recycled newspaper that is treated with chemicals to make it fire-retardant and to repel pests; it does not totally eliminate them. Although it may be true that cellulose acts as a repellant, there is debate on how effective it is at repelling pests. More importantly, the chemicals cellulose is treated with can have detrimental effects to your health as well as create some major dust issues in your home. Unfortunately, both were the case for our new client.
The first thing we did was assign one of our Certified Energy Auditors and a Heating and Air Conditioning Technician to evaluate his home. Our team discovered that there was a considerable amount of dust and chemicals entering the home. We determined that the ductwork in the home was improperly installed and that the attic was not properly sealed. This was creating an unbalanced, negative-pressure condition every time the system would operate. The home’s envelope was vulnerable to attic air being pulled in by the heating and air conditioning system and the condition of the duct work.
Resolving the pressure issue certainly helped the situation but it did not eliminate the entire problem. Next, we recommended testing his indoor air quality to discover the root cause of his family’s respiratory issue. Our air quality test screens for harmful chemicals, toxins and air pollutants. The diagnosis of the air quality test indicated that the home had extremely high levels of formaldehyde!
Where was formaldehyde coming from???…… HIS NEW CELLULOSE INSULATION!
We recommended removing all of the cellulose insulation installed by the pest control company and providing him with a much healthier product, blown in fiberglass insulation. His respiratory issues were so bad; he didn’t bat an eye and left the rest in our hands to correct. All that expense just to fix a rodent issue which in turn created a much more serious problem, a health problem for his family!
We are happy to report, once the cellulose was replaced with blown in fiberglass, our new customer reported a comfortably happy and much healthier family!

What is unsealed duct work?
As your heart needs arteries and veins for carrying blood around your body, similarly, your heating and AC equipment requires duct work to spread out the conditioned air throughout the house. However in most homes, roughly 20 to 30% of the air that flows through the duct work escapes into the attic or crawlspace depending on its location through leaks in your unsealed duct work and system. The unsealed or leaky duct work can causes many problems with your system and increases your bills dramatically. Sealing of ducts is extremely important, however the level of importance goes up, if the ducts are located in an unconditioned area such as an attic, garage or a crawl space.
What causes duct leakage?
• Harsh weather conditions in unconditioned air spaces, like our Dallas area 160 degree attics
• The ducts become torn & worn out from excessive use in long Texas summers
• Improper installation, Laying on attic floors, insufficient insulation and improper sizing
• Damage caused by insects, pests, rodents and contractors stepping, sitting or crawling over.
Disadvantages of unsealed ducts:
• Enormous waste of energy, since about 10-30% of the of an average unit’s output is wasted due to duct leakages which wouldn’t occur if ducts are sealed properly. Energy losses can also occur when the central furnace fan is not running or operational. There are five ways through which an unsealed duct causes energy losses:
– Conduction: Hot 160 degree attic air outside the poorly insulated or unsealed ducts heats the duct walls, which in turn causes the cold air inside the ducts to become warmer than it should, causing your unit to work longer and harder to cool your home
– Air leakage: At times, the cause of these air leaks could be damaged or poorly connected unsealed ducts that allow conditioned air to escape into the attic or crawlspace instead of going into your home.
– Leaky supply ducts: In this case, the supply ducts are leaking, but the return ducts are fully intact. This causes energy loss in two ways; the energy loss caused, which does not go into the rooms and/or extra amount of energy required to heat up the cold air that leaked inside the house.
– Leaky return ducts: This is the opposite case where the return ducts hot air in summer or cold air in winter to get pulled into the system while the supply ducts remain intact. Since the return ducts operate at a higher pressure than the house supply ducts or the outside, cold air or hot air depending on season from the outside surroundings is pulled into this return duct. What happens then is that this cold air along with the air that came into the house through return registers, is heated in the furnace, which causes an imbalance since the amount or air that came in the house through the supply ducts becomes greater than what the return ducts took away from the house. To balance it out, cold air is pulled in and warm air leaks out.
• Unsealed ducts allow dirty and unconditioned air to be pulled back inside the house causing the air around you, to become polluted and turning into a health hazard. This dirty air can also cause instill dangerous dusts and microbes which can lead to lung and respiratory diseases. Dirty air can cause the inside of your system to age and fail prematurely.
• The energy waste caused due to unsealed ducts means your system runs longer than it should
• Rooms become stuffy.
• High summer and winter utility bills.
• Indoor temperature variations.
• Decreases life of heating/cooling systems.
How to seal a duct?
Since the ducts are often located inside walls, garages, attics and basements- it becomes difficult to repair them, but there’s always something that you can do about a situation. Firstly, a thorough investigation is to be carried about the location and intensity of the duct leakage. You can either choose to seal the ducts inside your house, on your own, or you can hire a professional, such as Efficient Home Solutions, to do this for you.
Conclusion: Even when your unsealed ducts are not damaged or worn out, they can be a cause for air leaks which again leads to all the problems stated above, such as high energy consumption, health risks, increased electricity expenses, etc. Effective duct sealing has a direct impact on your wallet, health, as well as on the environment as a whole.
