"We had three zones installed for our older home that had no central air. The installation was clean, fast, and professional. Now every room is perfectly comfortable and our electric bills are actually lower than when we used window units. Best home investment we've made."
"Installed a single zone in our master bedroom and it's been amazing. Whisper quiet, energy efficient, and keeps the room perfectly cool in summer and warm in winter. Homets Air did a great job with the installation and explaining how everything works."
"Converted our entire home from baseboard heat and window ACs to a 5-zone mini-split system. The difference is incredible — every room stays comfortable, energy costs dropped significantly, and the house is so much quieter. Professional installation from start to finish."

Most single-zone installations take 4-8 hours to complete. Multi-zone systems typically require 1-2 days depending on the number of indoor units and complexity of the installation. We work efficiently while maintaining the highest quality standards to minimize disruption to your home.
Yes — modern mini-split heat pumps provide reliable heating even in freezing temperatures. High-efficiency models can operate effectively down to -13°F. They're actually more energy-efficient than traditional gas or electric furnaces, which can significantly reduce your heating costs during Nassau County winters.
With proper annual maintenance, ductless mini-split systems last 12-20 years on average — longer than most traditional HVAC systems. The key to longevity is regular filter cleaning (every 1-2 months) and professional yearly maintenance including coil cleaning, refrigerant checks, and electrical inspections.
Absolutely. Single-zone mini-splits are far more efficient and comfortable than window units. They provide superior cooling and heating, operate quietly (as low as 19 dB), offer precise temperature control, improve air quality with multi-stage filtration, and add value to your home. The energy savings alone often justify the investment within a few years.
Yes — we offer flexible financing options to make energy-efficient mini-split installation affordable. Many homeowners choose financing to upgrade to multi-zone systems or higher-efficiency models. Contact us to learn about current financing rates and monthly payment options.
If your outdoor unit has the capacity to support additional zones, yes — you can add more indoor air handlers later. During the initial consultation, we help you plan for potential future expansion by selecting an appropriately sized outdoor condenser. This flexibility is one of the major advantages of mini-split systems.
Not at all. Mini-split installation is minimally invasive. We drill a small 3-inch hole through the wall for the refrigerant and electrical line set, mount the indoor and outdoor units, and seal everything cleanly. There's no major construction, no drywall removal, and we protect your floors and furniture throughout the process. Most customers are surprised by how clean the installation is.
Mini-splits require minimal maintenance. Homeowners should clean or replace indoor unit air filters every 1-2 months (takes 2 minutes). Professionally, we recommend annual service including coil cleaning, refrigerant pressure checks, electrical inspections, drain line flushing, and outdoor condenser cleaning. Proper maintenance ensures maximum efficiency and prevents costly repairs.
