What's Included in Our Service

The Work We Actually Do

We install central air systems, heat pumps, mini-splits, furnaces, and boilers. Every installation includes proper sizing calculations, ductwork inspection, and system testing. You’re not getting an oversized unit that cycles on and off constantly or an undersized one that runs nonstop and never keeps up.

Our air conditioning repair in Hempstead, NY covers refrigerant leaks, compressor failures, electrical issues, and airflow problems. We also handle heating maintenance in Hempstead, NY—cleaning burners, checking heat exchangers, testing safety controls, and replacing filters. These aren’t optional if you want your system to last past its warranty.

Nassau County homes built before 1990 often have ductwork issues that waste 20-30% of your heated or cooled air. We inspect ducts during service calls and let you know if sealing or insulation would actually save you money. We also install air quality systems—filtration, purification, humidifiers, and dehumidifiers—because indoor air in Long Island homes can be five times more polluted than outdoor air, especially if your system isn’t circulating properly.

How do I know if I need HVAC repair or a full replacement?

If your system is under 10 years old and the repair costs less than half the price of a new unit, repair usually makes sense. If it’s over 15 years old, breaking down frequently, or the repair estimate is close to replacement cost, you’re better off replacing it.

Here’s what we look at: age of the unit, frequency of past repairs, efficiency rating, and whether parts are still available. Older systems use R-22 refrigerant, which is expensive and hard to find now. If your AC needs a refrigerant recharge and it’s using R-22, replacement is often the smarter move.

We’ll give you both options with honest pricing. Some contractors push replacement because the ticket is bigger. We’d rather you trust us for the next repair or the next system down the road.

It depends on your square footage, insulation, window count, ceiling height, and how much sun hits your house. A 1,500-square-foot home might need a 2-ton unit or a 3-ton unit depending on those factors. Guessing wrong costs you money and comfort.

Oversized systems cool or heat too fast, then shut off before removing humidity. You end up with a cold, clammy house in summer. Undersized systems run constantly, wear out faster, and never quite get the temperature where you want it.

We do a Manual J load calculation for every installation. It’s the industry standard, but a lot of contractors skip it and just match the old unit size. That’s lazy, and it’s why so many systems underperform. You’re paying for the equipment either way—might as well get one that actually works right.

Once a year minimum for each system. Get your heating system serviced in the fall before you need it, and your cooling system serviced in the spring. If you run a heat pump year-round, service it twice a year.

Regular maintenance catches problems early—like a cracked heat exchanger that could leak carbon monoxide, or a refrigerant leak that kills efficiency and eventually destroys your compressor. It also keeps your system running at peak efficiency, which matters when you’re paying Long Island energy rates.

Most manufacturers require annual maintenance to keep your warranty valid. If your system fails and you haven’t kept up with service, they can deny your claim. We keep records of every maintenance visit so you’re covered.

Your system is working harder to do the same job. That happens when filters are clogged, coils are dirty, refrigerant is low, or ductwork is leaking. Even a 15% efficiency drop adds up fast on a monthly bill.

Dirty evaporator coils make your AC run longer to reach the same temperature. Low refrigerant forces your compressor to work overtime. Leaky ducts pump expensive heated or cooled air into your attic or crawlspace instead of your living room.

Sometimes it’s the system itself. If your furnace or AC is over 15 years old, it’s just not as efficient as newer models. A new high-efficiency heat pump can cut your heating costs by up to 75% compared to an old furnace or baseboard heaters. We’ll test your current system and tell you whether a repair, a tune-up, or a replacement makes the most sense for your situation.

Call us. We handle emergency HVAC repairs in Hempstead, NY and can usually get someone out the same day or next day depending on the schedule. In the meantime, there are a few things you can check yourself.

Make sure your thermostat is set correctly and has working batteries. Check your circuit breaker—sometimes a tripped breaker is the whole problem. Look at your air filter; if it’s completely clogged, replace it and see if that helps. If your outdoor unit is frozen over or covered in debris, turn the system off until we can look at it.

Don’t keep running a system that’s clearly struggling. You’ll make the problem worse and the repair more expensive. And don’t try to fix refrigerant leaks or electrical issues yourself—that’s how people get hurt or make a $300 fix into a $3,000 one.

Yes. We handle HVAC services in Hempstead, NY for homes and businesses. Commercial systems are bigger and more complex, but the principles are the same—proper installation, regular maintenance, and fast reliable repairs when something breaks.

Commercial buildings have different needs than homes. You might need zoned climate control, better air filtration for customers and employees, or a maintenance plan that keeps your system running during business hours. We’ve worked on retail spaces, offices, and small commercial buildings throughout Nassau County.

Whether it’s a heat pump service in Hempstead, NY for your house or a full commercial HVAC installation for your business, we size the equipment correctly, install it right, and service it so it lasts. The same standards apply regardless of building size.
