When your AC quits during a Long Island summer, every hour counts. The humidity climbs. The house gets stuffy. You start sweating through the day and can’t sleep at night.
You need someone who shows up when they say they will, figures out what’s wrong without the sales pitch, and fixes it right the first time. That’s what our residential AC repair in North Hempstead, NY is built around—getting your comfort back without dragging you through a complicated process or pushing services you don’t need.
We handle everything from refrigerant leaks and compressor failures to electrical issues and airflow problems. Most repairs happen the same day. You get a clear price before we start, and the work comes with a warranty because we stand behind what we do.
Your home should feel like a refuge when it’s 90 degrees outside. We make sure it does.
Excellent Air Conditioning and Heating Service has been keeping North Hempstead homes comfortable for years. Glenn, the owner, runs the business the way you’d want it run—he shows up himself, explains what’s happening with your system in plain terms, and gives you options without the pressure.
We know how North Hempstead homes are built. We understand the humidity that rolls in off the Sound and how hard your AC has to work during July and August. Our crew lives in Nassau County, so when you call, you’re talking to neighbors who know exactly what you’re dealing with.
We’re licensed, insured, and we don’t play games with pricing. If your system can be repaired, we’ll repair it. If it’s time for a replacement, we’ll tell you why and show you the numbers. You make the call.
You call or contact us online. We ask a few quick questions about what’s going on—no cooling, strange noises, leaking water, whatever you’re seeing. Then we schedule a time that works for you, often the same day if it’s an emergency.
When we arrive, we run a full diagnostic on your system. We check refrigerant levels, inspect electrical components, test airflow, and look at the compressor and condenser. Most issues show up pretty quickly when you know what to look for.
Once we find the problem, we walk you through it. We explain what failed, why it happened, and what it’ll take to fix it. You get an upfront price before any work starts—no surprises on the invoice later.
If you’re good with the quote, we handle the repair right there. We carry most common parts on the truck, so there’s usually no waiting around for orders to come in. After the fix, we test the system to make sure everything’s running the way it should. Then we clean up and get out of your way.

Our central AC repair in North Hempstead, NY covers the full system—compressors, condensers, evaporator coils, refrigerant lines, thermostats, electrical connections, and airflow components. If it’s part of your air conditioning system, we work on it.
We handle common issues like AC units that won’t turn on, systems blowing warm air, refrigerant leaks, frozen coils, water pooling around the unit, and loud or unusual noises during operation. We also troubleshoot ductless mini-splits, including Fujitsu and Mitsubishi systems that are popular in older North Hempstead homes where adding ductwork isn’t practical.
Long Island summers are brutal on AC systems. The constant humidity and heat put stress on components, especially if your unit’s been running for years without maintenance. Capacitors fail. Contactors wear out. Refrigerant leaks develop. These aren’t always signs you need a new system—they’re just signs you need a solid repair from someone who knows what they’re doing.
We use quality parts from brands like Trane and Carrier because we’re not interested in coming back to fix the same problem twice. You’re paying for a repair that lasts, not a temporary patch.
If your system is less than 10 years old and the repair costs less than half the price of a new unit, fixing it usually makes sense. That’s the general rule most HVAC professionals follow.
But age isn’t the only factor. If your AC has needed multiple repairs in the last couple of years, if your energy bills keep climbing even though you’re not using it more, or if it’s struggling to keep up during hot weather, replacement might be the smarter move. We’ll walk you through the math when we’re at your house—what the repair costs now, what you’re likely to spend over the next few years, and what a new system would run you.
We’re not going to push you toward a sale if a repair makes sense. But we’re also not going to let you sink money into a system that’s on its last legs. You’ll get honest advice based on what we see, and then you decide.
Warm air coming from your vents is the big one. If your thermostat’s set to cool and the air blowing out isn’t cold, something’s wrong—usually a refrigerant leak, a failed compressor, or an issue with the condenser outside.
Weak airflow is another red flag. If some rooms aren’t cooling or the air feels barely there, you might have a blower motor problem, a clogged filter, or ductwork issues. Water pooling around your indoor unit means the condensate drain is clogged or the drain pan is cracked. That needs to get fixed before you end up with water damage.
Strange noises—grinding, squealing, banging—are never normal. Those usually point to worn bearings, loose parts, or a failing motor. And if your AC is cycling on and off constantly or won’t stay running, that’s often a thermostat issue, a sensor problem, or an electrical fault. Don’t ignore any of these. The longer you wait, the worse (and more expensive) it gets.
Most repairs fall somewhere between $150 and $600, depending on what’s broken and what parts are needed. A simple fix like replacing a capacitor or a contactor is on the lower end. A refrigerant recharge or a blower motor replacement costs more.
Compressor replacements are the expensive ones—often $1,200 to $2,500—because the compressor is the heart of the system and the labor is intensive. At that point, if your system is older, we’ll usually recommend looking at replacement instead because you’re halfway to the cost of a new unit.
We give you the price before we do the work, so there’s no sticker shock when we hand you the bill. And we’ll tell you if a repair doesn’t make financial sense. You’re not going to get upsold here—you’re going to get the truth and a fair price.
Yes, whenever possible. We know that waiting around in a hot house isn’t an option during summer, especially if you’ve got kids, elderly family members, or health conditions that make the heat dangerous.
We keep our schedule flexible during peak season specifically so we can handle emergency calls. If you reach out in the morning, there’s a good chance we can get to you that afternoon. If it’s later in the day, we’ll do everything we can to fit you in before evening.
Same-day service depends on our current workload and parts availability, but we carry the most common components on our trucks, so most repairs happen on the spot. If we need to order a part, we’ll let you know upfront and get it handled as fast as possible. We’re not going to leave you sweating for days if we can help it.
Absolutely. We work on ductless systems all the time, especially Fujitsu and Mitsubishi units, which are common in North Hempstead homes. A lot of older houses here don’t have ductwork, so ductless mini-splits are the go-to solution for adding AC without tearing up walls.
These systems have their own quirks. The indoor units can develop drainage issues, the outdoor condenser can have refrigerant leaks, and the electronic controls sometimes fail. We’ve seen it all and know how to troubleshoot each brand’s specific issues.
If your mini-split isn’t cooling, is leaking water, or is throwing error codes, we can diagnose and fix it. We also handle multi-zone setups where one outdoor unit runs several indoor heads. Whether it’s one zone acting up or the whole system, we’ll get it sorted.
Turn the system off first. Continuing to run it will just make the leak worse and could cause water damage to your floors, walls, or ceiling below the unit.
Water leaks usually happen because the condensate drain line is clogged. Your AC pulls moisture out of the air, and that water has to go somewhere—normally through a drain line to the outside. When that line gets blocked with algae, dirt, or debris, the water backs up and overflows from the drain pan inside your house.
Sometimes the drain pan itself is cracked or rusted through, especially in older systems. Or the evaporator coil could be frozen, and when it thaws, it dumps more water than the pan can handle. We’ll figure out which one it is, clear the blockage or replace the pan, and make sure it doesn’t happen again. Don’t wait on this one—water leaks get expensive fast if they’re ignored.
