Types of Heat Pumps We Service
Alliance Heating & Air Conditioning services a full range of residential heat pump systems across Connecticut and the New York suburbs. Whether you’re dealing with an aging unit, considering an upgrade, or simply need seasonal maintenance, our team is trained to service all major types of heat pump technology:
Air-Source Heat Pumps
The most common type found in homes today, air-source heat pumps offer efficient heating and cooling using the outside air. We repair, maintain, and install both standard and high-efficiency models to help homeowners lower energy bills without sacrificing comfort.
Ductless Mini-Split Systems
Perfect for homes without central ductwork or for supplemental climate control in additions, sunrooms, and multi-level homes. We service all leading mini-split brands and configurations—from single-zone units to complex multi-zone setups.
Geothermal Heat Pumps
Looking to go green? Geothermal systems harness stable underground temperatures to provide ultra-efficient comfort all year long. As IGSHPA-certified specialists, our team services both horizontal and vertical loop systems.
Hybrid (Dual-Fuel) Heat Pumps
These systems pair a traditional gas furnace with a heat pump to optimize efficiency depending on the weather. When temperatures drop too low for a heat pump to work efficiently, the gas furnace kicks in automatically. We maintain and repair these smart systems to ensure seamless performance.
Whether your heat pump was installed last year or a decade ago, our licensed experts have the tools and training to keep it running at peak performance. If you’re unsure which type you have, give us a call—we’ll help you identify it and recommend the right service to match.

Signs Your Heat Pump Needs Service
Because heat pumps provide both heating and cooling, there are some unique red flags to watch for—especially in regions like Connecticut and the New York suburbs, where seasonal swings demand year-round performance.
Here’s what homeowners in areas like Bridgeport, Fairfield, and Westchester County should look out for:
Your system is stuck in one mode
If your heat pump won’t switch between heating and cooling, the reversing valve may be failing—a common issue in older dual-mode systems.
Ice forming on the outdoor unit (even when it’s not freezing out)
While frost is normal in winter, thick ice in mild weather can point to defrost cycle failures or low refrigerant—especially common during shoulder seasons in coastal towns like Milford.
Blowing cool air during winter—or warm air during summer
This often signals a refrigerant issue, compressor failure, or a malfunctioning reversing valve—problems unique to heat pumps, not furnaces or central AC.
Noticeable drop in efficiency compared to last season
Because heat pumps run all year, wear and tear happens faster. If your energy bills are up but usage hasn’t changed, it’s time for a tune-up or diagnostic.
Outdoor unit running constantly in cold weather
On colder Connecticut nights (especially inland in areas like Trumbull or Danbury), a heat pump might need auxiliary heat—but if it’s running non-stop even when mild out, there may be a control or sensor problem.
System shuts down during defrost cycle
If your system suddenly stops heating mid-cycle, you may have a sensor or control board issue—best diagnosed by a technician familiar with heat pump behavior.
Loud whooshing or hissing sounds
These are often normal during defrost mode, but if they’re new or persistent, it may indicate a stuck valve or refrigerant imbalance.
Older system relying too heavily on backup heat
If you notice the emergency heat or auxiliary strip heat kicking on more often (especially in towns like Stamford or White Plains), it may be a sign your heat pump can’t keep up on its own.
If something feels off with your heat pump, trust your instincts—and call the pros. At Alliance Heating & Air, we’ve seen it all. Whether it’s a small performance dip or a full system failure, we’ll help you get ahead of the problem with expert repair, maintenance, or replacement services across Connecticut and the New York suburbs. Fast response, honest answers, and reliable comfort—that’s the Alliance difference.

Why Heat Pumps are Ideal for Homes Near The Sound
Being close to the ocean has a moderating effect on our area’s weather. Sure, it can still get quite hot in August, and thinking about those February mornings can make you shiver, but most of the time, our local climate is pretty desirable. That consistency in weather makes heat pumps the ideal choice for our area.
We Know the Right Heat Pumps for New York & Connecticut
Homeowners can choose any heat pump from any of the world’s manufacturers, but when Alliance Heating and Air Conditioning recommends a specific unit, it’s because we know what works best for our area’s unique climate. We’ve been installing and serving heat pumps since 1979, so our team has plenty of firsthand experience at knowing which models are best for our area’s challenges. Our goal is to find you the perfect balance of comfort and efficiency.
Frequently Asked Heat Pump Questions
What’s the difference between a heat pump and a traditional HVAC system?
A heat pump provides both heating and cooling using a single system—it transfers heat rather than generating it. That makes it an energy-efficient option for climates like Connecticut and New York, where you need year-round comfort without two separate systems.
How do I know if my heat pump needs repair or just maintenance?
If your system is still running but seems less efficient (e.g., longer cycles, uneven temperatures, increased utility bills), it may just need maintenance. But if you’re hearing loud noises, smelling burning odors, or the unit isn’t switching modes, it likely needs professional repair.
Do heat pumps work well in cold Connecticut winters?
Yes—modern cold-climate heat pumps are designed to perform efficiently even in sub-freezing temperatures. In some cases, homeowners pair them with auxiliary systems for backup during extreme cold snaps common in Fairfield and Westchester Counties.
How often should I service my heat pump?
We recommend servicing your heat pump twice a year—once in spring before cooling season, and once in fall before heating season. This ensures optimal performance and helps extend system lifespan, especially in high-demand areas like coastal Connecticut.
Do you install ductless mini-split heat pumps?
Absolutely. We install and service both central heat pump systems and ductless mini-splits, which are ideal for older homes, additions, or rooms without ductwork. They’re a popular option in many Westport and Greenwich-area homes.
What brands of heat pumps do you service?
We service all major brands, including Trane, Mitsubishi, Carrier, Lennox, and ClimateMaster. Whether it’s a standard air-source system or a geothermal heat pump, our NATE-certified technicians are trained to get the job done right.
Do you offer financing for new heat pump systems?
Yes. We offer flexible financing options to help Connecticut homeowners upgrade to energy-efficient heat pumps without the upfront burden. Ask us about available rebates and seasonal promotions as well.
