Answers to Common Questions

We recommend having your comfort system maintained twice a year. A twice-yearly maintenance plan helps keep your air conditioner operating efficiently, catches small issues before they turn into bigger (and costlier) problems, and can even extend the lifespan of your equipment. While most manufacturer warranties require only annual maintenance, scheduling tune-ups in both the spring and fall is the best way to protect your investment, ensure warranty compliance, and maintain year-round comfort.

Programmable thermostats can give you considerable control over your climate. And those that are connected to Wi-Fi allow you to adjust the temperature from your phone, whether you’re in the house, in the city, or halfway across the country. The savings add up quickly, and most programmable thermostats pay for themselves in less than a year.

Yes, air conditioners and heat pump systems are designed to remove humidity as they cool your home. In fact, when Willis Carrier invented air conditioning, his original goal was to create a dehumidifier; the cooling effect was simply a fortunate bonus! Today’s variable-speed systems are even better at managing humidity because they run longer at lower speeds, allowing more moisture to be removed from the air.

In most homes, this built-in dehumidification is enough to keep indoor humidity levels around 50%, which is the ideal range for comfort and efficiency. For homeowners who want extra humidity control, we can install a whole-home dehumidifier to work alongside your comfort system. Managing humidity properly not only improves indoor comfort but can also help you save on energy costs since lower humidity makes your home feel cooler at higher thermostat settings.

These acronyms stand for Energy Efficiency Ratio and Seasonal Energy Efficiency Ratio. EER measures the cooling output of your air conditioner under peak load. SEER measures the efficiency of your air conditioner based on the seasonal average.

Regular maintenance, inspections, frequent filter changes, and keeping the area around your AC unit clean are all ways to prevent AC emergencies. Catching an issue early is the best way to make sure your air conditioner doesn’t have a major breakdown.

The cost to replace your home’s comfort system can vary significantly based on your home’s size, your efficiency goals, and the type of system that works best for you. Because HVAC pricing can fluctuate with market conditions and equipment availability, we recommend speaking with one of our Comfort Specialists. At Greens Energy, our team takes the time to understand your needs and will recommend options that align with your comfort goals and budget. We’re here to make the replacement process straightforward and help you choose the right system for your home.

Before deciding which type of AC system to install, consider the size of the space, environment, energy requirements, and cooling needs. Our HVAC professionals at Greens Energy can perform an assessment to determine which system will best meet your needs.

We recommend that all HVAC equipment be replaced at the same time. If one part of the HVAC system breaks and needs replacing, you have the option to replace only that one part, but it is more efficient and cost-effective to replace the entire system.

If your current system is over 10 years old, requires frequent repairs, or struggles to cool your home efficiently, it may be time to consider a replacement. Our professionals can help you determine if a new AC system is your best choice.

The size of the air conditioner you need for your home depends on its square footage, insulation, and layout. Our Comfort Advisors can run an HVAC load calculation that will determine the exact system size for your home.

Why Is My Air Conditioner Not Blowing Cold Air?

If your AC is not keeping your home cool, it could be due to a few common issues. A refrigerant leak, dirty coils, a faulty thermostat, or blocked ductwork may be the cause. The team at Greens Energy, your local Lake Nona AC repair company, has been helping Central Florida families since 1953. We take the time to perform complete AC system diagnostics, unit inspections, and HVAC system troubleshooting so you can get back to enjoying cool air.

How Much Does It Cost to Fix My AC?

Every central air repair is different. Small services, like coil cleaning or thermostat adjustments, are generally affordable. Larger repairs, such as compressor failure or duct revisions, take more time and materials. At Greens Energy, we always put customers first. We provide clear pricing before we start any work and offer flexible financing options so families and homeowners can get the repairs they need without the stress.

Seasonal HVAC Maintenance Plans for Lake Nona Homes & Businesses

Taking care of your HVAC system is one of the smartest ways to prevent costly repairs down the road. With the Greens Comfort Club, our seasonal maintenance includes coil cleaning, drain line flushing, outdoor coil washing, and safety checks. We also check system performance and replace filters if provided by you. Routine care helps improve energy efficiency, maintain good indoor air quality, and keep your system dependable. Lake Nona families count on Greens Energy to protect their comfort year-round.

How Do I Know if My HVAC System Needs to Be Repaired or Replaced?

If your system is making noise, cooling unevenly, or driving up your energy bills, it is time for a closer look. Our experienced AC contractors perform complete HVAC system troubleshooting and provide honest recommendations. If a repair makes sense, we will take care of it. If a new energy-efficient system would better serve your home, we will guide you through the process so you can feel confident in your choice.

How Often Does My HVAC System Require Maintenance?

The best way to keep your HVAC system working its best is with professional maintenance twice a year: once before peak cooling season and once before heating. Our Greens Comfort Club tune-ups include thorough coil cleaning, drain line flushing, outdoor coil washing, safety inspections, and filter replacement if provided. Regular maintenance lowers energy costs, helps prevent breakdowns, and keeps your home’s air clean and healthy.
