Brockton Heating and Cooling Services

Brockton winters bring single-digit temperatures, while summer humidity makes homes feel swampy. Your HVAC system handles both extremes—from January cold snaps to August heat waves.

GEM provides comprehensive Brockton heating and cooling services to make sure your system is always working at its best. Our team handles everything from emergency repairs and routine maintenance to full system installations and replacements.

Cooling System Icon

Air Conditioning

Central AC uses your existing ductwork to cool every room in your home.

When summer heat settles over Plymouth County, a properly functioning AC system is essential. GEM installs and services high-efficiency central air systems designed to handle Massachusetts summers while managing energy costs. Whether you’re in a Brockton Heights ranch or a downtown multi-family, we deliver reliable cooling.

Most AC failures happen on the hottest days when systems run hardest. Regular service prevents the majority of breakdowns, and when something does go wrong, our technicians pinpoint the issue and fix it right.

  • Air Conditioning Repair: Warm air blowing, ice on the coils, strange noises, system cycling on and off. We troubleshoot the actual cause and make repairs that last.
  • Air Conditioning Maintenance: Spring tune-ups catch small problems before summer heat arrives. We clean components, verify refrigerant levels, test electrical connections, and clear drain lines.
  • Air Conditioning Installation: Proper sizing matters. An oversized unit cycles too frequently; undersized equipment runs constantly. We match the system to your Brockton home’s square footage, insulation, and layout.
  • Air Conditioning Replacement: When repair costs approach replacement value, or your system hits 15+ years, upgrading makes sense. New units run quieter, cool more evenly, and cut energy bills.

Furnaces

Furnaces deliver fast, reliable heat for Brockton homes with existing ductwork.

Available in gas, oil, and electric models, furnaces provide reliable and efficient warmth all winter long. They’re especially common in Brockton’s Campanelli ranches, newer construction, and updated homes. Furnaces quickly heat homes and maintain consistent comfort even when temperatures plunge.

GEM’s team of licensed professionals provides complete furnace services to keep your system running safely, efficiently, and reliably all season.

  • Furnace Installation: We’ll help you select the ideal furnace for your home based on its size, layout, and comfort needs. Our installation ensures your new system is properly sized and ready to deliver dependable heat.
  • Furnace Replacement: If your furnace is aging or struggling to keep up, it may be time for an upgrade. GEM replaces outdated units with high-efficiency models designed to improve comfort and reduce energy costs.
  • Furnace Repair: When your furnace stops working or isn’t heating evenly, our technicians respond quickly to restore warmth and safety. We diagnose accurately and make thorough, lasting repairs.
  • Furnace Maintenance: Prevent breakdowns and extend your furnace’s lifespan with regular maintenance from GEM. Our detailed tune-ups include cleaning, inspections, and performance checks.
Heat Pump Icon

Heat Pumps

Heat pumps offer year-round comfort with exceptional energy efficiency.

Heat pumps work differently from most other HVAC systems. Instead of generating heat, they simply push it into or away from the home. This highly efficient process keeps your home comfortable while lowering energy bills—a smart choice for Brockton homeowners watching their budget.

GEM is proud to be a Mass Save®-approved installer, offering expert heat pump services in Brockton and access to valuable rebates for qualifying systems.

  • Heat Pump Installation: Our team designs and installs heat pump systems tailored to your home’s layout, size, and comfort goals. With precise installation, you’ll enjoy consistent temperatures and maximum efficiency.
  • Heat Pump Replacement: If your heat pump is aging or struggling to maintain comfort, it might be time for an upgrade. GEM provides seamless replacements using the latest high-efficiency models.
  • Heat Pump Repair: When your system isn’t heating or cooling as it should, our technicians quickly identify the issue and make lasting repairs. From airflow problems to component failures, we restore performance.
  • Heat Pump Maintenance: Routine maintenance keeps your heat pump running at peak efficiency through every season. GEM’s service includes inspections, cleaning, and adjustments to prevent breakdowns.
Ductless Icon

Ductless Mini-Splits

Ductless systems provide targeted heating and cooling without traditional ductwork.

Ductless mini-splits are ideal for Brockton’s older triple-deckers and multi-family homes without existing ductwork, plus additions, converted attics, and finished basements. They provide targeted heating and cooling without invasive construction.

These systems are quiet, energy-efficient, and give you the freedom to customize temperatures room by room. GEM’s experts install and service ductless systems for Brockton homeowners looking for flexible, efficient comfort.

  • Ductless Mini-Split Installation: Our technicians design and install ductless systems tailored to your home’s unique layout. Each unit operates quietly and blends seamlessly into your space.
  • Ductless Mini-Split Replacement: When your current system struggles to maintain comfort or efficiency, GEM can upgrade you to a new high-performance model.
  • Ductless Mini-Split Repair: If your mini-split isn’t cooling, heating evenly, or responding properly, our team will diagnose the issue and fix it fast.
  • Ductless Mini-Split Maintenance: Regular maintenance keeps your ductless system operating efficiently. GEM’s service includes cleaning filters, inspecting components, and checking refrigerant levels.
Boiler Icon

Boilers

Boilers provide steady, even warmth through radiators and underfloor systems.

Many of Brockton’s older homes—especially the triple-deckers and multi-families throughout downtown and North Brockton—rely on boiler systems for dependable heat. GEM offers complete boiler services including installation, repair, maintenance, and replacement to keep these reliable systems running safely.

Technician Icon

Radiant Heating

Radiant systems deliver consistent warmth without the drafts of forced air.

Radiant heating eliminates cold spots by evenly delivering warmth through floors, walls, or ceilings. Found in some of Brockton’s older homes and increasingly popular in renovations, radiant heat provides comfortable, allergen-free warmth. GEM offers comprehensive radiant heating solutions.

Oil to Gas Conversions

Massachusetts has one of the highest rates of oil heat in the country.

Many older Brockton homes still run on oil. Switching to gas heating can lower operating expenses, eliminate fuel deliveries, and reduce maintenance headaches. Gas heating offers cleaner performance and more reliable comfort.


GEM makes the transition simple with expert oil-to-gas conversion services that handle every step, from permits to final safety checks.

Auto CAD Icon

Zoning lets you control temperatures in different areas of your home independently.

A zoned HVAC system divides your home into separate temperature zones—especially useful for Brockton’s multi-level homes and larger properties. GEM designs and installs custom zoning solutions that improve comfort and reduce energy waste.

HVAC FAQs

What’s the best heating system for a Brockton home?

The right system depends on your home’s age, layout, and existing infrastructure. Many older Brockton triple-deckers use boilers with radiators, while Campanelli ranches and newer homes typically have furnaces. Heat pumps are increasingly popular for their efficiency. A professional assessment from GEM can help you choose the best option.

What rebates are available for Brockton homeowners?

As a Mass Save®-approved installer, GEM can help you access valuable rebates and incentives on qualifying high-efficiency heat pump systems and other equipment. These programs can significantly reduce your upfront installation costs for Massachusetts residents.

How often should I schedule HVAC maintenance in New England?

With Plymouth County’s extreme temperature swings, we recommend scheduling maintenance twice a year—once in spring before cooling season and once in fall before heating season. Regular service helps prevent breakdowns and keeps your system efficient.

Why is my heating bill so high in winter?

Brockton winters push heating systems hard, but unusually high bills often indicate issues like poor insulation, aging equipment, or deferred maintenance. Older triple-deckers especially can benefit from efficiency improvements. GEM can assess your system and recommend solutions.

How long do HVAC systems last in the Massachusetts climate?

Most HVAC systems last between 10 and 20 years, but New England’s demanding climate can accelerate wear. Systems in older Brockton homes that run constantly through frigid winters and humid summers benefit from regular maintenance to maximize lifespan.
