You’re not looking for a lecture about HVAC systems. You need your home comfortable again before the heat becomes unbearable for your family.
Most AC breakdowns in Uniondale happen during the worst possible time—mid-July heat waves when every HVAC company is slammed. You’re stuck waiting days for a callback while your electric bill climbs from running a system that’s barely keeping up. Or worse, you’re dealing with a unit that’s completely dead and a house that feels like a sauna by noon.
Our AC repair services in Uniondale, NY focus on getting your system diagnosed and fixed fast. We show up when we say we will, explain exactly what’s wrong before touching anything, and give you a clear price before we start the work. No drawn-out diagnostic periods that add $150 to your bill. No vague explanations that leave you wondering if the problem’s actually fixed.
You get a technician who knows how older homes in Uniondale behave—the wiring quirks in houses built in the 1950s, the ductwork issues common in ranch-style layouts, the way humidity affects systems differently here than other parts of Nassau County. That local knowledge means faster diagnosis and repairs that actually last.
Excellent Air Conditioning and Heating Service has been handling residential AC repair in Uniondale, NY and throughout Long Island for years. Our technicians aren’t just passing through your neighborhood—they’re your neighbors.
That matters when you’re dealing with an emergency. We understand the housing stock here, from the post-war Cape Cods to the split-levels that dominate certain blocks. We know which systems tend to fail first in homes from the 1950s and 1960s, and we stock the parts that those older units actually need.
We’re not the company that shows up and immediately pitches you a $12,000 replacement. Sometimes you need a new system. Often you don’t. Our job is to tell you the truth about what’s happening with your equipment, what it’ll cost to fix, and how long that fix will realistically last. Then you decide what makes sense for your home and your budget.
You call or contact us online, and we schedule a time that actually works for your schedule. If it’s an emergency during a heat wave, we prioritize same-day service because we know you can’t wait three days in a house that’s 85 degrees.
A technician arrives and starts with a full system diagnostic. That means checking refrigerant levels, testing electrical components, inspecting your condensate drain line, examining the compressor and fan motor, and running a complete analysis of how your system is actually performing. We’re looking for the real problem, not just the obvious symptom.
Once we identify the issue, we explain what’s wrong in plain terms. No technical jargon meant to confuse you. We tell you what needs to be fixed, what it costs, and what happens if you don’t fix it. You approve the work, and we complete the repair with quality parts that are built to last.
After the repair, we test the system to make sure it’s running efficiently. We check the temperature differential, verify airflow, and make sure you’re getting the cooling performance you’re paying for. Then we walk you through what we did and answer any questions you have about maintaining your system going forward.

Our home AC repair in Uniondale, NY covers the full range of issues that cause systems to fail or underperform. Refrigerant leaks that slowly kill your cooling capacity. Compressor failures that shut down your entire system. Electrical problems that cause your unit to short cycle or not turn on at all. Condensate drain clogs that lead to water damage inside your home.
We handle central AC repair in Uniondale for all major brands—Trane, Carrier, Lennox, Goodman, Rheem, and others. If you’ve got a ductless mini-split system from Fujitsu or Mitsubishi, we service those too. Age doesn’t scare us off either. We work on systems that are 5 years old and systems that are 20 years old.
For homes in Uniondale specifically, we see a lot of issues related to older electrical systems that weren’t designed for modern AC loads. Houses built in the 1950s often have undersized breaker panels or outdated wiring that causes units to trip repeatedly. We can identify those issues during our diagnostic and explain your options—sometimes it’s a simple fix, sometimes it requires an electrician, and we’ll be straight with you about what’s needed.
We also test for carbon monoxide as part of our service, especially important in older homes where heating and cooling systems share ductwork. That’s not an upsell—it’s basic safety that should be standard in every HVAC service call.
If your AC dies during a heat wave, we prioritize emergency calls for same-day service. That doesn’t mean we’ll be there in 30 minutes like a pizza delivery, but we’ll get someone to your home the same day if you call before early afternoon.
During peak summer months when everyone’s AC is working overtime, response times can stretch a bit. But we’re not the company that tells you “maybe Thursday” when you call on Monday. We give you a realistic timeframe and stick to it.
If it’s not an emergency—say your system is limping along but still producing some cool air—we’ll schedule you within a day or two. The key is being honest with us about what you’re experiencing so we can prioritize appropriately.
Repair costs depend entirely on what’s actually broken. A clogged condensate drain line might cost $150 to clear. A failed capacitor runs $200-300. A refrigerant leak that needs to be found, sealed, and recharged could be $500-800. A dead compressor on an older unit might be $1,500-2,500.
We don’t do pricing games. Once we diagnose the problem, we give you an exact price before starting any work. That price includes labor, parts, and testing to make sure the repair actually fixed the issue.
Here’s what matters more than the repair cost: whether the repair makes sense for your situation. If you’ve got a 17-year-old system that needs a $1,800 compressor replacement, we’re going to have an honest conversation about whether that’s smart money or if you’re better off putting that toward a new system. We’re not going to push you either way—we’ll give you the information you need to make the right call for your home.
Age and repair cost are the two biggest factors. If your system is under 10 years old and the repair costs less than $1,000, fixing it almost always makes sense. If your system is over 15 years old and needs a major repair that costs more than $1,500, replacement often makes more financial sense.
But there’s more to consider. How many repairs have you done in the past few years? If you’re calling for service every summer, you’re throwing money at a dying system. How high are your energy bills? Older systems lose efficiency over time, and you might be spending an extra $50-100 per month in electricity compared to a newer, efficient unit.
We’ll walk you through the math during our service call. We’ll show you what the repair costs, what a new system would cost, and what you’d save in energy bills with a replacement. Then you decide. Some homeowners want to squeeze another few years out of their current system. Others are ready to upgrade and stop dealing with constant repairs. Both choices are valid—we just make sure you have the real numbers to make an informed decision.
Yes, and we see them constantly. Uniondale has a lot of homes built in the 1950s and 1960s, and many still have HVAC systems that are 15-25 years old. We’re comfortable working on older equipment, and we stock parts for systems that other companies consider obsolete.
The challenge with older systems isn’t usually the AC unit itself—it’s everything around it. Outdated electrical panels that can’t handle the load. Ductwork that’s deteriorated or was poorly designed from the start. Thermostats that are wildly inaccurate. Refrigerant types that are being phased out and becoming expensive to refill.
We’ll tell you honestly what we’re dealing with. Sometimes an older system just needs a straightforward repair and will run fine for a few more years. Sometimes the system is fine but the infrastructure around it is causing problems that’ll require additional work. And sometimes the system is so far gone that repairing it is just delaying the inevitable. Whatever the situation, you’ll know exactly where you stand before we do anything.
Refrigerant leaks are huge, especially in systems over 10 years old. The coils develop small leaks over time, refrigerant slowly escapes, and your system loses cooling power. Homeowners usually notice their AC running constantly but never quite reaching the temperature on the thermostat.
Electrical failures are also common in older Uniondale homes. Capacitors burn out, contactors fail, and wiring connections corrode. These issues cause systems to short cycle, trip breakers, or fail to start at all. In houses with older electrical panels, we sometimes see the AC pulling too much current and causing problems throughout the home’s electrical system.
Condensate drain clogs are another frequent issue, especially during humid Long Island summers. When that drain line backs up, water overflows inside your home—usually into your basement or utility closet. It’s an easy fix if caught early, but it can cause serious water damage if ignored.
Dirty coils and filters also cause a surprising number of problems. When airflow gets restricted, your system works harder, runs hotter, and fails sooner. Regular maintenance prevents most of these issues, but if you’ve skipped maintenance for a few years, we can get your system cleaned up and running properly again.
Yes. All our repair work is backed by a service warranty that covers both parts and labor. The specific warranty length depends on the type of repair and the parts used, but we stand behind everything we do.
If we replace a component and it fails within the warranty period, we come back and make it right at no additional cost. That’s not some fine-print warranty with a dozen exclusions—it’s straightforward coverage that protects your investment.
We also install quality parts from manufacturers that offer their own warranties. When we put in a new compressor, condenser fan motor, or other major component, you’re covered by both our labor warranty and the manufacturer’s parts warranty. We’ll explain all the warranty details before you approve any work, so you know exactly what’s covered and for how long.
