HVAC Company in Hempstead, NY

Dalton Heating & Air handles HVAC work across Hempstead, NY with written pricing before any work starts and a full-year guarantee on every repair. Hempstead’s mix of older post-war homes, newer construction, and Long Island humidity means systems here run hard from June through September and get pushed again in winter. Call (361) 306-9515 and a live person answers, 24 hours a day.

Why Hempstead Homes Are Different

Hempstead’s housing stock spans a wide range: 1950s ranches and colonials sit next to newer builds, and many older homes still run original ductwork that was sized for heating only. When a homeowner adds central air to those systems, the ducts often underserve the second floor. We see this regularly in neighborhoods around Clinton Street and near Hofstra, where homes from that era share the same layout DNA. The real impact: a properly sized AC unit paired to older ducts still delivers uneven cooling, so part of our job is checking airflow before condemning equipment.

Long Island humidity also changes how systems behave. An air conditioner in Hempstead does two jobs at once: it drops temperature and strips moisture from the air. When the coil runs too warm or the fan speed is set too high, the house feels clammy even at 72 degrees. That is a control and charge issue, not a comfort preference, and it is fixable. Winter is its own animal. Salt air from the south shore works on outdoor condenser coils, and homes near the Hempstead Turnpike corridor tend to accumulate more debris on condensers than quieter side streets off Front Street.

Permitting here is straightforward for most repairs: swapping a capacitor, contactor, or control board does not require a permit. Full system replacements do, and a licensed contractor pulls it and closes it out. If you are in a village within the Town of Hempstead with its own building department, the paperwork goes through that office, not the town. We handle that on replacement jobs.

Our Main Hempstead Services

Most Hempstead homeowners call us first about two things: an air conditioner that stopped cooling in July, or a furnace that will not stay lit in January. Each service below has its own page with local pricing, what the job involves, and what to expect from the first call to the final invoice.

AC Repair in Hempstead

When an air conditioner quits in Hempstead in August, the most common culprits are a failed capacitor, a refrigerant leak at the evaporator coil, or a condenser fan motor that seized. We diagnose these on site, put the price in writing before touching a screwdriver, and stock the common parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard systems. Many Hempstead AC repairs are done same-day because the parts are already on the truck. A refrigerant recharge is not always the fix: a system that is low on refrigerant leaks from somewhere, and adding fluid without finding the leak is money that disappears by next spring. AC Repair in Hempstead explains what we check and what repair costs look like.

Heat Pump Installation in Hempstead

Heat pumps are a practical fit for Hempstead homes that want one system for both cooling and heating, especially in the shoulder seasons of April and October when switching between AC and furnace is overkill. A heat pump installation in this area means a load calculation on the actual square footage and window orientation, not a rule-of-thumb guess. We see older homes around Fulton Avenue and Terrace Avenue where a poorly sized heat pump would short cycle and never hit set temperature on a humid August night. The installation page covers sizing, what the job includes, and why the written proposal stays the written proposal. Heat Pump Installation in Hempstead

Furnace Repair in Hempstead

A furnace that will not fire in a Hempstead February is usually one of three things: a failed igniter, a clogged flame sensor, or a gas valve that is not opening. All three are repairable, and none of them require a new furnace on the spot. When a furnace does need replacing, the decision should be made calmly in October, not in a panic at 9pm on a 12-degree night. We service gas furnaces, oil furnaces, and hydronic systems in Hempstead, and the repair includes a written guarantee: if the fix does not hold for a full year, we return at no charge.

Pricing for HVAC Company in Hempstead, NY

Service Typical range in Hempstead
AC Repair $150 – $650
Furnace Repair $150 – $700
AC Installation $3,500 – $7,500
Tune-Up $80 – $200

Those ranges reflect what most Hempstead jobs actually cost. A capacitor swap lands at the low end. A repair that involves a compressor or a replacement coil climbs toward the top. Age and accessibility move the number too: a furnace wedged into a tight crawlspace near Hempstead Turnpike takes longer than one in an open basement. The written price you approve before we start is the final price. No add-ons at the door, no surprise line items.
