Outdated Air Conditioning Systems

If your home’s air conditioning system is more than ten years old, it’s likely outdated and inefficient. Modern air conditioning units offer profound energy savings, greater control, and safer coolants that do not damage the environment. Upgrading to a new HVAC system could be the best solution for your home, depending on your budget and needs. A new system will provide uniform cooling and heating throughout your home, ensuring your comfort and satisfaction.

Blocked Vents

Blocked vents are another common reason for uneven cooling and heating in homes Furniture or other objects may block the air flow vents preventing proper airflow This can be resolved by simply moving the objects that are blocking the ventilator or vacuuming the air vent to remove dust and debris

Dirty Air Filters

Dirty air filters can clog the vents and prevent the constant flow of air, limiting circulation and causing potential problems for your HVAC unit. Clean air filters are essential to ensuring proper airflow, improving indoor air quality, and extending the lifespan of your HVAC system.

Leaking Air Ducts

Leaking air ducts can significantly impact the performance of your HVAC system, leading to uneven cooling and heating in your home. The air ducts can develop leaks due to damage, age, or poor installation. If you suspect that your air ducts are leaking, call Snyder Air Conditioning, Plumbing & Electric at (904) 877-9836. An experienced HVAC technician can inspect and repair any leaks, ensuring optimal performance of your HVAC system.

Inadequate Insulation

Inadequate insulation can lead to uneven cooling and heating in your home. Insulation helps to ensure that hot air stays out and cool air stays in. It’s crucial to have the appropriate amount and quality of insulation in your attic to maintain comfortable indoor temperatures. Additionally, your attic needs proper ventilation to keep heat and moisture out. An HVAC expert from Snyder can help you determine if your insulation is adequate and recommend solutions if needed.

Install a Zoned System or Ductless Mini-Split System

Zoned systems and ductless mini-split systems are great solutions for homes with multiple floors or rooms with different cooling and heating needs. Zoned systems split your home into multiple “zones” with separate controls for each area. Dampers in your ductwork electronically control the heating and cooling in your home, providing only the areas in need of cooling with air. Separate thermostats can even allow you to customize each zone for your comfort. Ductless mini-split systems utilize air handlers in different areas of your home instead of dampers in the vents, providing more control over each room’s temperature.

Regular HVAC Maintenance

Lastly, it’s important to maintain your HVAC system regularly by scheduling yearly professional maintenance. Professional technicians can make sure your HVAC system is working efficiently and catch any issues before they become costly problems. By implementing these solutions, you can enjoy a comfortable and consistent temperature throughout your home and save money on energy bills in the long run.

Customer Reviews

This was an exceptional experience! We woke up to our A/C on but not cooling (it was 6am and already 81 in the house). The person who set up our appointment was very nice, able to get us seen same-day, and let us know of some options to help save us money.

-Christy Cormier

The service from Sam and Chris was excellent! They were very knowledgeable and professional. They were able to answer all of my questions and completed all of my electrical issues. I will definitely use them again for future jobs. Thank you!

-Adrienne Beal

From the get go I could tell that the Snyder employees were truly professionals and didn’t push to make sales like other companies I’ve talked to my whole life. They took the time to explain so that I could make a decision. The installers and later the duct cleaners were very respectful during their work here. Thank you.

-Crystal Hill

Snyder provided an amazing experience from start to finish. Most of us dread getting estimates with pressuring salespeople. Erik was a great guy, explained all my options and didn’t try to pressure me to act quickly! Justin followed up with my husband and I to offer further assistance in our decision. Again, no pressure, just helped with our follow up questions.

Snyder was easy to get in contact with and had availability the next day. Clint came out and needed some parts so had to reschedule us for the next day for installation.
