Same-Day Service & Membership Plans for Nassau County Homeowners

Five Star Mechanical has provided residential HVAC service throughout Nassau County since 2011. Our team is licensed, bonded, and insured, and we offer same-day service calls for Garden City homeowners dealing with heating or cooling problems that can’t wait. From routine seasonal maintenance to emergency repairs, we handle the full range of residential HVAC needs under one roof.

Call (516) 447-2113 or contact us online to schedule residential HVAC service in Garden City.

Residential HVAC Services We Provide

We cover the full scope of residential heating and cooling for Garden City homes. Whether you’re replacing an aging central air system, adding a ductless mini-split to a new addition, or scheduling a pre-season tune-up, our technicians arrive equipped to handle the work.

Our residential services include:

  • HVAC installation and replacement – System selection and sizing matched to your home’s square footage and layout, using brand-name equipment from Comfort Maker, Bryant, Mitsubishi Electric, and Fujitsu.
  • Heating repair and maintenance – Furnace repair, heat pump service, boiler service, and seasonal tune-ups to support reliable heating through Nassau County winters.
  • Air conditioning repair and maintenance – Central AC and ductless mini-split service, including repairs, replacement, and preventive maintenance ahead of summer.
  • Ductless mini-split installation and repair – Dedicated service for ductless systems, well suited to older homes without existing ductwork and for zone-controlled comfort.
  • Indoor air quality solutions – Air purifiers, filtration systems, humidifiers, and ventilation upgrades for healthier air inside your home.
  • Boiler services – Repair and maintenance for the hydronic heating systems common in many older Nassau County homes.

Why Garden City Homeowners Call Us First

With over 15 years of experience serving Nassau County, we’ve built a reputation on showing up on time, doing the work right, and being transparent about what it costs. Our pricing reflects fair, competitive rates with no hidden fees. Customers consistently note on-time arrival, thorough workmanship, and single-day job completion. One review specifically mentioned that our crew included a licensed electrician and wrapped the full installation in one visit.

We work with brand-name equipment because the systems we install are selected for season-after-season performance. Our team is licensed, bonded, and insured, which means you have a clear point of accountability on every service call, not just a contractor who shows up and disappears.

Frequently Asked Questions

How often should I schedule HVAC maintenance?
Twice a year is the standard recommendation: once in the spring before cooling season and once in the fall before heating season. Our residential membership plans are built around that schedule, with two included maintenance appointments per year. Staying on that schedule can reduce the likelihood of mid-season breakdowns and help your system run efficiently.

What are the signs my system needs repair or replacement?
Common warning signs include uneven heating or cooling between rooms, energy bills rising without a clear explanation, unusual noises like rattling or grinding, and the system cycling on and off without reaching the set temperature. System age matters too: units 10 to 15 years old or older are worth evaluating, especially when repair costs are climbing. If you’re seeing any of these signs, a same-day service call can help identify whether repair or replacement makes more sense for your situation.

Residential Heating Services in Garden City

Nassau County winters put real demand on residential heating systems. When a furnace fails to ignite, heat distribution becomes uneven, or a boiler starts cycling without reaching temperature, the problem rarely resolves on its own. Our team offers same-day heating service calls so Garden City homeowners aren’t left waiting through a cold night for help to arrive. We’ve been serving Nassau County since 2011 and understand the heating systems common in homes throughout the area.

We handle heating repair, installation, replacement, and maintenance across the range of residential equipment found in Garden City homes. That includes:

  • Furnaces – Furnace repair and seasonal tune-ups for consistent warm airflow through winter.
  • Heat pumps – Installation and service for systems that provide both heating and cooling from a single unit.
  • Boilers – Repair and maintenance for the hydronic heating systems common in older Nassau County homes.

Whatever system your home relies on, our licensed technicians work to restore reliable heat and keep it running efficiently through the season.

Air Conditioning Services for Garden City Homes

Long Island summers bring sustained heat and humidity that accelerate wear on systems that aren’t receiving regular maintenance. We provide a full range of residential air conditioning services to help keep your home comfortable all season, and we’re equipped to address problems before they become failures. Our team is licensed, bonded, and insured on every call.

Our air conditioning services include:

We work on both central air conditioning systems and ductless mini-splits. Ductless systems are a popular choice for home additions, older homes without existing ductwork, and spaces where zone-controlled cooling makes sense. If you have questions about which system fits your home, our team can walk you through the options.

Residential HVAC Membership Plans

We offer membership plans designed to give Garden City homeowners consistent coverage and priority access without the uncertainty of paying full price every time something comes up. Each plan covers your system for up to one year.

Plan options for residential properties:

  • Combo heating and air conditioning service agreement
  • Air conditioning-only service agreement
  • Heating-only service agreement

Every plan includes two maintenance appointments – one in the spring and one in the fall – so your system gets a professional inspection at the start of each demanding season. Beyond the maintenance visits, members have their standard diagnostic fees waived and receive a $100 discount on emergency service diagnostic fees. Preferred scheduling for service calls comes with membership as well.

For homeowners who want reliable coverage without managing it appointment by appointment, a membership plan is a practical way to stay ahead of problems and reduce what you pay when something goes wrong.

Call (516) 447-2113 or contact us online to schedule service or learn more about our residential HVAC membership plans.
