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 stops cooling, it can be frustrating, especially during Florida’s long summers. Sometimes the cause is simple, like a dirty filter or a thermostat issue. Other times, it may be something more complex, like a refrigerant leak or blocked ductwork. Our Lake Mary AC repair company will carefully inspect your system, explain what is happening, and provide the right solution to get cool air flowing again.

How Much Does It Cost to Fix My AC?

The cost of central air repair depends on your system’s needs. Simple adjustments such as coil cleaning or thermostat calibration are quick and affordable. Larger repairs, like replacing a compressor or fixing a refrigerant leak, will cost more. No matter what, we will clearly explain your options and offer financing if needed so you can make the choice that works for your family.

Seasonal HVAC Maintenance Plans for Lake Mary Homes & Businesses

Preventative maintenance is one of the smartest ways to keep your HVAC system working efficiently in Lake Mary’s long cooling season. Our Greens Comfort Club includes indoor and outdoor coil cleaning, clearing drain lines, inspecting electrical connections, and checking fan motors. Routine maintenance helps prevent breakdowns, improves energy efficiency, and protects your investment all year long.

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

If you are noticing things like uneven cooling, unusual noises, or higher utility bills, it may be time to have your HVAC system checked. Our team will inspect it fully and give you an honest recommendation. If a repair will keep it going strong, we will take care of it. If a new energy-efficient system would save you money in the long run, we will guide you through your options without pressure.

How Often Does My HVAC System Require Maintenance?

To keep your system running smoothly, we recommend having it inspected and maintained twice a year: once before summer and once before cooler months. During a maintenance visit, we check all key components, clean coils, inspect ductwork, and more! Regular service improves efficiency, prevents unexpected problems, and helps maintain a healthy home environment.
