AfterHVAC Company in Andover, MA
Dalton Heating & Air handles heating and cooling work across Andover, MA, from split-level ranches near Phillips Academy to newer construction off Route 133. Most HVAC calls in Andover come down to two things: aging equipment in homes built between the 1950s and 1980s, and New England winters that punish any furnace not running at full capacity. We give you a written price before any work starts, a written guarantee on every repair, and the repair is covered for a full year. If it fails in that time, we return at no charge. Call (361) 306-9515 for a free estimate.
Why Andover Homes Are Different
Andover’s housing stock runs older than most Essex County suburbs. A good share of homes near the town center and along School Street were built before central air was standard, which means retrofit ductwork, tight mechanical closets, and furnaces shoehorned into basements not designed for modern equipment. Those installs take more care than new construction work.
The climate compounds it. Winter nights in Andover regularly drop into the teens, and a furnace that loses its heat exchanger mid-January is an emergency, not an inconvenience. Summers have gotten hotter, adding load to AC systems in homes where cooling was added decades after the house was built. We also see a lot of heat pump interest from homeowners off Main Street and in the neighborhoods around Haggetts Pond, where residents want one system that handles both seasons. Andover’s permit office requires proper mechanical permits for new installs and equipment replacements, and our crews pull the right paperwork on every job.
Our Main Andover Services
Most Andover homeowners call us for one of three things: a furnace or AC system that stopped working, or a heat pump install to replace aging equipment. Here’s how each job goes in Andover specifically.
AC Repair in Andover
Central air tends to fail during the first real heat wave of the year, and in Andover that often means a condenser unit sitting in full sun off the back of a colonial, fighting to push cool air through ductwork that was never sized for it. Common failures include capacitor burnouts, refrigerant leaks – a slow loss of the cooling fluid your system needs to hit set temperature – and contactor failures that keep the outdoor unit from turning on. Most AC repairs in Andover run $150 to $650 depending on the part. We stock common capacitors, contactors, and fan motors on our trucks, so a technician can usually get your system running the same day. Every repair comes with a written guarantee. See what’s covered on our AC Repair in Andover page.
Heat Pump Installation in Andover
A heat pump moves heat instead of generating it, which makes it an efficient fit for Andover’s shoulder seasons and for homeowners tired of maintaining separate furnaces and AC condensers. Install work here often means upgrading an electrical panel, adding a new outdoor unit, and sometimes reworking duct connections in older basements. Trane, Lennox, and Goodman systems are common requests from Andover homeowners replacing oil or propane heat. A full heat pump install typically runs $3,500 to $7,500 in this area, and we handle the load calculation, the permit, and the paperwork for any Mass Save rebates. Read the full breakdown at our Heat Pump Installation in Andover page.
Furnace Repair in Andover
When a furnace quits in Andover in January, the problem usually traces to a failed igniter, a dirty flame sensor, or a blower motor that gave out after years of steady use. Those repairs range from $150 to $700, and a technician can often diagnose and fix the issue on the first visit. We service furnaces in Andover basements every winter and carry igniters, flame sensors, pressure switches, and blower motors on the truck. Gas furnaces need special attention around the heat exchanger – a cracked exchanger can leak carbon monoxide, and that’s a job no homeowner should attempt themselves. See typical repair costs at our Furnace Repair in Andover page.

Pricing for HVAC Company in Andover, MA
| Service | Typical range in Andover |
|---|---|
| AC Repair | $150 – $650 |
| Furnace Repair | $150 – $700 |
| AC Installation | $3,500 – $7,500 |

What pushes a repair toward the higher end of that range in Andover is usually the age of the equipment and the part that failed – a compressor costs more than a capacitor, plain and simple. For installs, ductwork modifications and electrical panel upgrades add cost. Whatever the number, you’ll have it in writing before any work begins. That’s the Garrison Standard: a written price on every job, no exceptions.
