Heating and Cooling Services in Johnston
Rhode Island weather tests your HVAC system. Frigid winters, humid summers, and everything in between. Your equipment works hard here.
GEM provides full-service heating and cooling for Johnston homes. Emergency repairs, routine maintenance, system replacements, new installations, all backed by 75 years of proven results.
Air Conditioning
Central AC keeps your whole house cool using your existing ductwork.
Rhode Island summers bring heat and humidity that window units can’t handle. GEM installs and services central air systems sized for your home, delivering even cooling without running up your electric bill. Repairs, maintenance, installations, we do it all.
- Air Conditioning Repair: Blowing warm air, making strange sounds, not turning on at all? We find the problem and fix it fast, usually same-day.
- Air Conditioning Maintenance: Spring tune-ups prevent summer breakdowns. We clean, test, and adjust your system before the heat arrives.
- Air Conditioning Installation: We calculate your home’s cooling load and install equipment that matches. Proper sizing means better comfort and lower bills.
- Air Conditioning Replacement: Old AC struggling to keep up? Modern equipment cools better, runs quieter, and uses less electricity.
Furnaces
Furnaces provide fast, dependable heat for homes with ductwork.
Gas, oil, and electric furnaces heat many Johnston homes, from the ranches in Thornton to newer builds throughout town. GEM services all types to keep your family warm when temperatures drop below zero.
- Furnace Installation: Proper sizing is everything. We match the furnace to your home’s heating load and ductwork for reliable, efficient performance.
- Furnace Replacement: Older furnaces waste fuel. Upgrading to high-efficiency equipment cuts heating costs and improves reliability.
- Furnace Repair: Not heating? Blowing cold air? Making strange noises? We troubleshoot the issue and get your heat back fast.
- Furnace Maintenance: Annual tune-ups keep your furnace safe and efficient. We clean, inspect, and adjust before winter hits.
Heat Pumps
Heat pumps heat and cool your home with one efficient system.
More Johnston homeowners are switching to heat pumps, and it makes sense. Modern units work well in Rhode Island winters, and Clean Heat RI rebates make them affordable. GEM is a participating installer with the expertise to do it right.
- Heat Pump Installation: We design and install systems sized for your home’s specific heating and cooling loads. Proper setup is essential for performance.
- Heat Pump Replacement: Older heat pumps struggle in cold weather. New cold-climate technology performs far better and costs less to run.
- Heat Pump Repair: Refrigerant issues, defrost problems, electrical faults? We diagnose and repair to restore your system’s performance.
- Heat Pump Maintenance: Seasonal service keeps your heat pump running efficiently and catches small problems before they become big ones.
Ductless Mini-Splits
Ductless systems heat and cool specific areas without running ductwork.
Ideal for homes without ducts, finished basements, additions, and converted attics. Mini-splits give you room-by-room control with quiet, efficient operation. GEM installs quality systems that handle Rhode Island’s climate.
- Ductless Mini-Split Installation: We configure single-zone or multi-zone systems to fit your home’s layout and your family’s comfort needs.
- Ductless Mini-Split Replacement: Older mini-splits lose efficiency over time. Current models run quieter and perform better in cold weather.
- Ductless Mini-Split Repair: Not heating or cooling right? Error codes flashing? We troubleshoot and fix issues to get your comfort back.
- Ductless Mini-Split Maintenance: Regular cleaning and service keeps your mini-split running efficiently and extends its lifespan.
Boilers
Boilers deliver steady, even heat through radiators and baseboard systems.
Many older Johnston homes, especially in Graniteville and established neighborhoods, rely on boilers. GEM’s licensed technicians handle gas and oil boilers, providing installation, repair, maintenance, and replacement to keep these reliable systems running.
Radiant Heating
Radiant floor systems warm your home from the ground up, eliminating cold floors and drafts.
Popular in Johnston renovations and new construction, radiant heat provides quiet, even warmth throughout. GEM designs, installs, and maintains hydronic radiant systems tailored to your project.
Oil to Gas Conversions
Natural gas reaches most Johnston streets. If you’re tired of oil, conversion is straightforward.
No more tank maintenance, fuel deliveries, or volatile oil prices. GEM manages the whole process: permits, equipment, gas line work, and final inspection.

Questions?
Indoor Air Quality Services in Johnston
The air inside your home matters. Dust, allergens, and humidity affect comfort and health. GEM offers solutions that work with your HVAC system.
We help Johnston homeowners breathe easier with air quality equipment that removes contaminants, controls moisture, and keeps indoor air fresh.
Air Purifiers
Whole-home purifiers capture allergens, dust, and pollutants that regular filters miss.
GEM installs air purification systems that work with your HVAC to continuously clean your indoor air, reducing allergy symptoms and improving overall health.
Air Filtration
Better filtration means cleaner air throughout your home.
GEM offers high-efficiency media filters and UV systems that trap smaller particles and neutralize bacteria and viruses before they circulate through your ductwork.
Humidity Control
Too dry in winter, too damp in summer. New England’s humidity swings cause real problems.
GEM installs whole-home humidifiers and dehumidifiers that automatically maintain comfortable moisture levels, protecting your home and improving comfort.
Thermostats
The right thermostat gives you better control over comfort and energy costs.
GEM installs everything from basic programmable models to smart thermostats you control from your phone. We make sure it works properly with your HVAC system.
Air Handlers
Your air handler circulates heated and cooled air to every room. Problems here affect your whole house.
Weak airflow? Uneven temperatures? Strange noises? These often point to air handler issues. GEM provides installation, repair, and maintenance to keep air moving properly.
More HVAC Services for Johnston Homes
GEM offers advanced services for complete comfort in your Johnston home.
We provide a range of additional HVAC services in Johnston including:
Ductwork
Leaky or poorly designed ducts waste energy and create hot and cold spots.
Many older Johnston homes have ductwork that needs attention. GEM tests, seals, repairs, and replaces ducts to ensure your system delivers comfort to every room.
Zoned HVAC
Zoning lets you heat and cool different areas of your home independently.
Stop conditioning empty rooms. GEM designs and installs zoning systems that deliver comfort where you need it while reducing energy waste.
Geothermal
Geothermal heat pumps use stable underground temperatures for remarkable efficiency.
Where lot conditions allow, geothermal can dramatically reduce your heating and cooling costs. GEM designs and installs these systems for Johnston homeowners looking for maximum efficiency.
Packaged HVAC
Packaged units put heating and cooling in one outdoor cabinet.
When indoor space is tight, packaged systems provide a practical solution. GEM installs and services these all-in-one units for Johnston homes where traditional setups don’t fit.

Johnston HVAC FAQs
How often does my HVAC system need maintenance?
Twice a year works best for Rhode Island’s climate. Service your cooling system in spring and your heating system in fall. Regular maintenance prevents breakdowns and keeps your system running efficiently.
How do I know if I need repair or replacement?
Rising energy bills, uneven temperatures, strange sounds, and frequent repairs all suggest problems. Equipment over 15 years old that needs major work is usually better replaced. We’ll assess your situation and give you honest options.
Do you work on older boilers and radiator systems?
Yes. Many Johnston homes, particularly in Graniteville and Thornton, have boiler heat. Our technicians maintain these systems regularly and can advise when repair versus replacement makes more sense.
Can I get same-day HVAC service in Johnston?
Usually, yes. Our fleet of 500+ trucks means we can respond quickly to Johnston calls. Same-day appointments are available for most routine service, and emergencies get immediate dispatch.
What rebates are available for Johnston residents?
Clean Heat RI offers rebates on qualifying heat pump installations. Rhode Island Energy has additional incentives for high-efficiency equipment. GEM helps you identify eligible programs and handles the rebate paperwork.
