- Insulate Well: Proper insulation keeps your home at a stable temperature, reducing the workload on your AC.
4. Smart Technology Use
- Smart Thermostats: Install a smart thermostat from brands like Nest or Ecobee. These can learn your habits, adjust settings automatically, and be controlled remotely via smartphone.
Signs of Energy Waste
Unsure if your AC is still wasting energy? Look out for these indicators:
- Uneven Cooling: Different temperatures in various rooms.
- Frequent Cycling: The AC turns on and off more than usual.
By fine-tuning these elements, you can maintain control over your AC and curtail unnecessary energy waste, all while keeping your home comfortably cool.
Unlocking Energy Efficiency with Air Sealing and Insulation
In the quest to enhance your home’s energy efficiency, two upgrades stand out: air sealing and insulation. These techniques work hand-in-hand to dramatically reduce energy waste, offering both environmental and economic benefits.
How Air Sealing Tackles Energy Waste
Air sealing addresses the numerous gaps and cracks found in a home’s structure. By meticulously closing these spaces, it prevents unwanted outdoor air from infiltrating your living spaces. This action ensures that your heating and cooling systems aren’t overburdened. With reduced strain, these systems consume less energy, which not only extends their lifespan but also cuts down your utility bills. Improved air quality and lower humidity levels are added bonuses, making your indoor environment healthier.
The Role of Insulation in Energy Conservation
Insulation complements air sealing by maintaining consistent indoor temperatures, regardless of weather fluctuations outside. This high-performance barrier ensures that your home retains heat during winter and stays cool during summer, requiring less energy to maintain comfort. As a result, your home’s overall energy consumption decreases, which lowers carbon footprint and reduces energy costs.
Incorporate these upgrades into your home to not only create a comfortable environment but also contribute to a more sustainable future. For those seeking detailed guides on installation, reputable resources are available to help you make informed decisions.
HOMEOWNER TROUBLESHOOTING STEPS FOR AC BLOWING HOT AIR
#1: CHECK THE THERMOSTAT
Check to make sure that your thermostat is set to COOL. If it is set to only FAN or HEAT, then switch it to COOL.
And check to see if it is set to be COOLER than the current temperature. Perhaps someone changed the setting without you knowing. Just lower the thermostat setting to a number below the current temperature in your home.
#2: CHECK VENTS THROUGHOUT YOUR HOME
Do you see that any of your vents are closed? If so, open them. Closed vents can cause problems with the air flow and cause your AC to blow warm. It’s a common misconception that vents should be closed in room not in use, but that is not correct. While a couple closed vents may be okay, too many can cause a problem.
#3: CHECK THE INDOOR HVAC UNIT
Most HVAC systems have a portion of the air conditioning system (the evaporator) located inside the home often in a closet or the attic. This evaporator absorbs heat from the air and transfers it to your outdoor AC unit (the condenser). This indoor unit has the fan that blows conditioned air through your home, and it does this even if your outside unit is not working. Check to make sure you hear the blower motor running.
#4: CHECK YOUR AIR FILTER
Is your filter dirty or clogged? While you are examining the inside unit, take a look at your air filter. If it is dirty or clogged, that could be the reason why your air conditioner isn’t blowing cold air. Simply changing it out for a clean air filter may get your system working correctly again.
To keep your air conditioner running efficiently, it’s crucial to know when to replace these filters. Generally, air filters should be changed every 90 days. However, certain conditions might require more frequent replacements:
- Home Size: Larger homes can put more strain on filters, potentially requiring swaps more often.
- Indoor Pets: Pets shed hair and dander, which can quickly clog filters.
- Smoking or Vaping: These activities introduce additional particles into your home’s air.
- Allergies: If anyone in your household suffers from allergies, cleaner air is essential, and more frequent filter changes can help.
By understanding these factors, you can better maintain your AC system and ensure it operates at peak performance. Regularly changing your air filter not only keeps the air in your home clean but also extends the life of your HVAC system.
Regular Maintenance for Efficient AC Operation
To ensure your air conditioner works efficiently, it’s crucial to clean the AC coils regularly. It is generally recommended to clean the coils at least once a year. Regular cleaning helps prevent the unit from blowing warm air and maintains optimal performance.
Key Reasons to Clean Annually:
Energy Efficiency: Clean coils reduce energy consumption and lower your electricity bills.
Extended Equipment Life: Dirt and debris can cause wear and tear, but regular cleaning helps prolong the lifespan of your AC.
Improved Air Quality: Dust-free coils enhance indoor air quality by minimizing allergens circulating in your space.
Signs It’s Time for a Cleaning
- Your AC is not cooling as effectively as it should.
- There’s an increase in energy bills without increased usage.
- Noticeable dust accumulation near vents.
By incorporating this annual maintenance into your routine, you ensure that your AC runs smoothly and efficiently all season long.
#5: CHECK THE OUTSIDE AC UNIT
Look at your condenser for problems. Is there frost or ice on it? What about leaves or debris? Your outdoor AC unit braves the elements year-round, so it’s no surprise that dirt and debris can gather. While a few leaves might seem harmless, they can cause significant issues.
Debris buildup around your unit can lead to overworking and overheating. This happens when airflow is restricted, forcing the system to work harder than necessary. The result? Your AC could end up blowing warm air instead of the cool relief you expect.
To prevent these issues, make it a habit to regularly check and clear any obstructions around your unit. A little maintenance goes a long way in ensuring your AC runs efficiently, saving you from unexpected repairs.
If it is frozen or has frost, change the setting on your thermostat from COOL to FAN. Let that run for as much as 12 hours to help your unit thaw. A frozen condenser is often caused by a dirty air filter, which is another reason why making sure you regularly change your filter is so important.
A frozen unit can happen when the coils on your evaporator become dirty or clogged. If that’s the case, clean the coil if you can access it. To get a good clean coil may require the coil is pulled out of the space it is in and Tommy Cool Air can help you with that.
If you do one of these steps and it only solves your problem temporarily, you may have a more serious issue. If the AC freezes up again, call Tommy Cool Air for 24/7 emergency AC repair service at (361) 852-4450. A freon leak could be what is causing the problem. We can come out and handle any potential leak, refill the system, and ensure it is back to working properly and safely.
When your AC isn’t blowing cold air, low refrigerant levels might be the culprit. Listen for a distinct hissing noise from the refrigerant lines—this could be a sign of a leak. Additionally, be on the lookout for ice buildup on your evaporator coils, especially if the unit is blowing warm air. These coils may be hidden, but if your system freezes up, it’s a possible indicator.
Important Steps to Take:
Turn Off Your AC: If you suspect a refrigerant leak, it’s crucial to switch off your AC immediately. Continuing to run it can cause further damage and poses health risks.
Understand the Risks: Refrigerant leaks can be toxic. Exposure may lead to sickness, so it’s imperative to act quickly and safely.

Identifying a Malfunctioning Compressor in Your AC Unit
A malfunctioning compressor is a key issue in an air conditioning system and pinpointing it can save you from further headaches. Here are the telltale signs that your AC compressor might be in trouble:
Lack of Cold Air: One of the most obvious signs is if your air conditioner is not blowing cold air. This is often a direct result of a faulty compressor failing to circulate refrigerant properly.
Unusual Noises: If you hear rattling, banging, or other odd sounds coming from your AC unit, it could indicate that the compressor parts are misaligned or deteriorating.
Physical Vibrations: Feeling excessive shaking or vibrations in your AC system is another sign of compressor issues. This can mean internal components are failing or imbalanced.
Moisture Leaks: Finding moisture or leaks near your AC could indicate problems with the compressor seal, leading to refrigerant leaks.
Recognizing these symptoms early can help in addressing compressor issues promptly, ensuring your air conditioning unit runs efficiently and effectively.
#6: CHECK YOUR HOME’S POWER
If you see that your AC isn’t blowing any air at all, then another thing to check is your home’s power supply. You may have blown a fuse and need to turn a switch back on inside your breaker box.
However, if your AC is running but only blowing warm air, you might be dealing with a tripped circuit breaker. Most AC units have two breakers: one inside your home and one outside.
First, inspect these breakers. If the outdoor breaker is tripped, it can cause the AC to function improperly, leading to that unwelcome blast of warm air.
A simple solution can often be found by resetting the tripped breaker. Just flip the switch back to the “on” position, and your AC should resume blowing cool air.
With these quick checks, you can potentially solve the problem without needing to call in professional help.
The Impact of Duct Leaks on AC Efficiency and Home Comfort
When you set your air conditioning system into action, you expect cool air to travel seamlessly through your home’s ducts, reaching every room. However, this journey isn’t always as smooth as planned.
The Challenge of Duct Leaks
Over time, air ducts can develop gaps or cracks through subtle shifts and wear. These small openings become escape routes for the cool air meant to keep your rooms comfortable. Instead of maintaining a consistent temperature, this escaped air often finds its way into attics or other unused areas, reducing the efficiency of your AC system.
Consequences on Home Climate
When your ducts leak, the system works harder to compensate for the lost air, which means more warm air might circulate in your living spaces, making it challenging to cool your home effectively. This not only compromises comfort but can also result in uneven temperatures across different rooms.
Efficiency Loss and Cost Implications
Energy Star reports that a significant 20–40% of conditioned air can be lost through duct leaks. Such wastage not only drives up energy bills but also puts additional strain on your AC system, leading to more frequent maintenance issues.
The Solution
To prevent such inefficiencies, it’s crucial to ensure proper air sealing and duct insulation. Addressing leaks in aging ductwork can significantly enhance both cooling efficiency and overall home comfort, ensuring your AC delivers its best performance year-round.
