Fast, Reliable AC Repair Across Hudson
Most AC repairs in Hudson run $150 – $650, and a same-day visit is usually possible when you call before noon. Dalton Heating & Air answers the phone with a live person 24/7, so you’re never leaving a voicemail while your house climbs past 85°F. Marco Benitez and our Hudson crews know the difference between an 1800s farmhouse off Main Street and a 1990s colonial off Cox Street, because that difference changes everything about how we diagnose your system. Call (361) 306-9515 and you’ll get a written price before any work begins, not after.
We stock parts for Trane, Lennox, Goodman, and Rheem units in our local trucks, which means fewer return trips and faster fixes when Hudson’s July humidity is at its worst. The price we quote is the price you pay. The repair is guaranteed in writing for a full year. If it fails in that time, we come back at no charge. That’s The Garrison Standard, and it’s been the rule on every job since 2003.
Why Dalton Heating & Air Is Hudson’s Preferred AC Repair Company
Hudson homeowners deal with a strange mix of housing stock. A colonial on Chestnut Street might have original 1960s ductwork pushing air through runs that were sized for a coal furnace, while a new build near Forest Avenue has tight insulation and an AC that short-cycles because it’s bigger than the house needs. A technician who only knows one of those houses will misdiagnose the other. Our crews have worked both.
We back every repair with a written guarantee, not a handshake. That’s the 365-Day Done Right Promise: if the work doesn’t hold for a full year, we return and fix it at no charge. No fine print, no prorated nonsense.
Reviews from Hudson customers mention the same things: the tech arrived inside the stated window, the price didn’t move, and the unit actually stayed fixed. We do not publish invented review counts or star ratings. We’ll point you to real customer feedback and let you decide.
Dispatch and scheduling are coordinated from the brand’s Boston office. Hudson crews handle the local work themselves. When you call, you get a live person who knows which route gets to Marlborough or Northborough without hitting the wrong bridge traffic, and who can tell you honestly whether we can get to your street today or first thing tomorrow.
AC Recharge in Hudson
An AC Recharge in Hudson means adding refrigerant to a system that’s lost charge, and in our experience the charge almost never just “wears out” – there’s a leak somewhere. In Hudson’s older homes, we often find slow leaks at Schrader valves or at brazed joints in the evaporator coil that have been weeping for years. The refrigerant itself is the symptom; the leak is the problem. A recharge without finding and sealing the leak is a temporary fix, and you’ll be calling again by August. Here’s what a proper recharge involves and what it costs in Hudson.
Leak Check First
Any reputable recharge starts with finding where the refrigerant went. We use an electronic leak detector and, on stubborn cases, a nitrogen pressure test. On a 12-year-old Goodman or Rheem system, a leak at an outdoor coil connection is common and usually repairable. If the leak is inside the evaporator coil, that’s a different conversation about repair versus replacement – we’ll walk you through it with real numbers, not scare tactics.
Refrigerant and Cost
An AC Recharge in Hudson, including the leak check and refrigerant, runs $150 – $650 depending on the system’s charge size and whether a leak repair is straightforward. R-410A systems cost less to top off than older R-22 units, and if you have an R-22 system, we’ll be direct with you: the refrigerant is being phased out and the per-pound cost is high. We’ll show you the per-pound price before we start.
Emergency AC Repair in Hudson
Emergency AC Repair in Hudson means a no-cooling call on a 90°F afternoon or a humid night when the house won’t drop below 80°F. We treat those calls as health and safety issues, not scheduling problems. A failed AC during a Massachusetts heat wave is dangerous for elderly residents, infants, and anyone with respiratory conditions. We prioritize no-cooling calls ahead of routine tune-ups, and we’ll tell you on the phone what our actual arrival window looks like – not a generic “sometime today.”
After-Hours Response
When your AC dies at 9 p.m. and the forecast says 88°F the next day, you don’t want a callback number. You get a live person at (361) 306-9515, any hour. We dispatch Hudson crews on the same priority as daytime calls, and the diagnostic fee doesn’t double just because the sun went down. Emergency AC Repair in Hudson runs $150 – $650, same range as our standard repair pricing, and the written-guarantee terms are identical.
What We Diagnose on Emergency Calls
In Hudson, emergency no-cooling calls break down into a handful of common culprits: a failed capacitor, a tripped float switch from a clogged condensate line, a blown contactor, or a refrigerant leak that finally dropped below the low-pressure cutoff. We bring capacitors, contactors, and float switches on the truck. Most emergency repairs finish in a single visit. When a compressor is dead or the coil is leaking internally, we’ll give you a straight repair-versus-replace breakdown on the spot, with a written price for both paths.
Trusted Brands We Service in Hudson
Our techs are factory-trained on nine major residential HVAC lines, and in Hudson we see a lot of Trane, Lennox, Goodman, and Rheem equipment – some of it pushing 15 years, some of it fresh from a builder install. We carry common parts for those brands on our trucks: capacitors, contactors, fan motors, pressure switches, and the usual wear items. If we need a less common part, our Boston dispatch can usually source it by the next morning, and we won’t make you wait at home all day for it. You tell us the brand, we’ll tell you whether we can fix it same-day or need a part run. No brand gets turned away.
Common AC Repair Problems We See in Hudson Homes
- High static pressure from undersized ductwork. Older Hudson homes with original supply runs push the blower harder than modern equipment is designed for, and the compressor ends up cycling on high head pressure. The unit “runs” but doesn’t cool, and the real fix is sometimes a duct modification, not a refrigerant top-off.
- Short-cycling from oversized equipment. Newer construction with tight building envelopes often has AC sized for a bigger house, so the system never runs long enough to dehumidify. The homeowner calls in July convinced the system is low on refrigerant. Usually it’s a sizing problem, and the evidence is in the cycle times we log during diagnosis.
- Clogged condenser coils from Assabet River valley pollen. Spring pollen plus river humidity cakes the outdoor coil fins faster than in drier towns. A dirty coil drives up head pressure, trips the high-pressure switch, and looks exactly like a refrigerant problem. A coil clean usually fixes it for $80 – $200 instead of a $400 recharge.
- Failed capacitors in aging condensers. For systems in the 8 – 15 year range around Hudson, a capacitor that reads below spec is the single most common failure we see in a heat wave. It’s a $150 – $350 fix. If the system is older and the capacitor has failed more than once, we’ll tell you honestly whether it’s time to stop repairing.

FAQs About AC Repair in Hudson
It’s usually a duct or airflow problem, not refrigerant. Homes from that era in Hudson often have supply runs sized for heating, not cooling, and the second floor gets starved. We measure static pressure and temperature split before adding refrigerant, because adding refrigerant to a duct problem doesn’t fix the upstairs and can damage the compressor. Call (361) 306-9515 and we’ll test the actual airflow, not guess.
For a system under 10 years old, a repair like a capacitor or contactor is almost always worth doing. For a system at 12 – 15 years with a failed compressor or a leaking evaporator coil, replacement usually makes more financial sense – the repair can exceed half the cost of a new unit. We’ll give you the repair quote and the replacement quote in writing, side by side, and let the numbers – not our commission – drive the decision. Our techs aren’t paid on what they sell.
SEER2 is the updated efficiency rating for cooling output per watt of electricity. Going from a 13-SEER2 system to a 17-SEER2 system typically cuts cooling energy use by roughly 20 – 25% – on a Hudson summer electric bill that often means $180 – $300 a year in savings, depending on your rates and runtime. The efficiency gain alone rarely justifies replacing a working system early. It matters most when you’re already replacing, because the difference between 14 and 17 SEER2 can pay back in 5 – 8 years in this climate.
We service all nine major residential brands we’re factory-trained on: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Hudson we see a lot of Trane, Lennox, Goodman, and Rheem units, but we’ll work on any of the nine regardless of who installed it or when. We stock common parts on the truck and can source less common ones by the next morning through our Boston dispatch.
In July, we prioritize no-cooling calls ahead of all routine work. Most Hudson same-day calls are reached within a few hours, and if you call before noon we can usually get a tech to your door that afternoon. Emergency and after-hours calls get the same priority and the same $150 – $650 range, with no after-hours markup. Call (361) 306-9515 and we’ll give you a real arrival window, not a vague promise.
If your AC is struggling and you want a straight diagnosis, a written price, and a repair that’s guaranteed in writing for a full year, call Dalton Heating & Air at (361) 306-9515. Marco Benitez and the Hudson crew will show up when we say we will and leave the site clean.
