Indoor Air Quality

You may not give it much thought, but the air you breathe indoors has real consequences for your health. Indoor air is frequently much more polluted than outdoor air, posing risks for everything from respiratory irritation to chronic diseases. The experts at Del’s Heating & Air Conditioning have a keen understanding of indoor air quality and how to manage it effectively. We offer a range of products and solutions to test and improve the quality of the air in your home or business, from a Reme Halo air purifier to UV light and air filters.

Maintenance Services

The importance of regular maintenance for your home or small business cannot be emphasized too often. A maintenance agreement will ensure that your system is prepared for all seasons of the year. Our maintenance agreement covers 2 service appointments during the year – in the spring and again in the fall. Not only will your warranty be maintained by these appointments, but your system will work at its most efficient level. We will often spot a trouble area that can be repaired easily that would otherwise turn into a costly repair if left unrepaired. We also offer one-time maintenance services and tune-ups.

Insulation Services

Extreme temperatures are tough on heating and cooling systems. You can tell how hard they are working when you look at your energy bills. If your energy bills are higher than expected, or have been creeping up, it may be time to take a look at the insulation in your attic. Over time, insulation becomes compressed, making it less effective allowing conditioned heated or cooled air to escape through your attic. We offer blown-in insulation that will bring your energy bills down and keep your home more comfortable whether it’s hot and humid or close to freezing outside.
