Pilot light or hot surface igniter failing repeatedly

Dead or bulging run capacitor on the condenser
Musty or burnt smell the first time the system runs
Heating and air conditioning service built around Nassau
If your boilers, gas furnaces and ductless mini-splits has started short cycling, blowing warm air or making a noise it never used to make, you are not alone — Nassau generates some of the highest call volume we handle in New York. Cold winters, humid city summers and a lot of older multifamily buildings that lean on boilers and ductless retrofits.
A large share of the equipment we service in Nassau was installed by a builder to a minimum spec. That usually means an undersized return, a cheap filter rack and a condenser sitting close to a wall.
Heating season here is October through April. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

Nassau12123 HVAC questions, answered
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Nassau see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
How quickly can a technician get to Nassau?
For the 12123 service area our target response time is 90-120 minutes from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
What brands do you service in Nassau?
All of them. Our 12123 technicians are trained on Heil, Goodman, Carrier, Bryant and essentially every other residential brand sold in New York, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Do you offer maintenance plans?
We do. A two-visit plan in New York covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
Do you service commercial and light commercial properties?
Yes. Around Nassau we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
