The system will not heat or cool
We check how the system responds and what is stopping it from doing its job. The repair should address the fault, rather than leave you relying on repeated resets.

AT A GLANCE
Home HVAC service starts with the comfort problem
Airplex repairs, installs, replaces and maintains home heating and cooling systems in NYC and Northern New Jersey. If a system stops working, the first job is to find the cause. If you are planning new equipment, the starting point is the rooms it must serve. A system can run without keeping the home comfortable; both the equipment and the way it delivers air or heat matter.

Something is wrong
Get to the cause of poor heating or cooling
The symptom helps guide the visit. It does not tell you which part needs replacing.
One room is too hot or too cold
A room problem can involve air delivery, controls or how the system serves the home. Replacing the whole system is not the only possible answer.
Water, noise or repeated shutdowns
These changes deserve a closer look. Tell us when they happen and which room or unit is affected; the technician can handle the equipment checks.
Keep a working system in good shape
Maintenance that fits the equipment
Routine care and fault repair have different jobs. A system that is already failing may need diagnosis as well as maintenance.
Airflow and heat transfer
Filters, coils and fans affect how well a system moves heat and air. Maintenance checks can reveal dirt, wear or other issues that need attention.
Controls and drainage
The system should respond to its controls and remove cooling condensate as intended. These are useful checks even when the home still feels comfortable.
A practical care plan
The equipment type, manufacturer guidance and use of the home shape the maintenance work. Ask which tasks are included and which repairs would be quoted separately.
Installing or replacing a system
Choose equipment around the home you want to live in
A new system should solve the comfort need that led you to replace or add it.
Replacing equipment that has failed
Compare the diagnosed repair with replacement, including parts availability, past faults and whether the old system met your needs when it worked.
Adding cooling or heating
Room layout, existing ducts, outdoor space and available electrical service help determine the options. Ductless and ducted systems suit different homes.
Renovating or adding a room
Bring HVAC into the plan before walls and finishes are complete. It is easier to assess equipment and pipe or duct routes while the layout is still being decided.
What was different before the home became uncomfortable?
A sudden change and a long-standing comfort problem lead to different questions. If every room stopped cooling yesterday, the immediate task is to find the fault. If one bedroom has always stayed warm while the rest of the home is comfortable, the visit should also consider how heating or cooling reaches that room.
Describe the result you want in everyday terms: sleeping comfortably with the bedroom door closed, getting reliable morning heat or cooling a new home office. That gives the technician a clearer goal than simply asking for a bigger unit. Equipment size, air delivery and the home itself all affect the result.
A useful repair recommendation explains the finding
Before approving repair work, ask what was found and how it relates to the complaint. A proposed control repair should explain the control problem. A drainage repair should explain the water path. When further investigation is needed, distinguish that next diagnostic step from a confirmed repair.
Also ask what the work leaves unchanged. Repairing a failed component may restore the system while leaving a separate comfort issue for another visit. This distinction helps you decide what needs attention now and what can be planned. It also gives you a clear point of comparison if the same symptom returns.
Compare ways to serve the rooms you actually use
An installation review should consider the home as it is today. A finished attic, changed room layout or new work-from-home routine may make the old arrangement a poor guide. Existing ducts, room-by-room needs, outdoor equipment space and the available routes for connections help shape the options.
For example, adding cooling to one regularly occupied room is a different brief from replacing heating and cooling throughout the home. This is an illustration, not a completed Airplex project. A focused addition may leave useful equipment in place; a whole-home plan should explain how all the intended rooms will be served.
Ask the proposal to identify equipment, installation work and separate building or electrical work. Where two options differ, compare the finished result and the work needed to achieve it, rather than comparing only the units on the quote.
Plan care around the equipment and the findings
Maintenance gives a working system attention before a reported breakdown; it is not a substitute for diagnosing an active fault. Useful care can include checks of controls, drainage and the parts that move air and transfer heat, as appropriate to the system. Ask which tasks apply to your equipment and what findings would lead to a separate repair proposal.
For a repair, access, the confirmed fault and the required parts shape the work. For installation, room coverage and connecting work matter as well. Ask whether removal, startup checks, controls and related work are included or separate. A clear scope helps you understand a price even before you choose between proposals.
WHAT TO EXPECT
From the first concern to a clear next step
Understand the problem
We start with what you are experiencing, then assess the equipment and the rooms involved.
Explain the options
The findings guide the next step: repair a fault, carry out maintenance or compare replacement choices.
Carry out the agreed work
The work and follow-up checks depend on the system and the approved repair or installation.
PLANNING THE WORK
What affects the cost of home HVAC work?
Repair cost depends on the fault, the parts and the access needed to complete the work. Installation also includes the connections that make the equipment work: air or refrigerant lines, drainage, controls and electrical work where needed. Compare what each proposal includes, not just the equipment price.
IN YOUR BUILDING
HVAC work in apartments, houses and attached homes
An apartment may have shared building systems or rules about outdoor equipment. A townhouse may need comfort across several floors with limited space for ducts. Airplex serves NYC and Northern New Jersey; the home layout and equipment access help shape the job.
COMMON QUESTIONS
Residential HVAC Services questions
Can I request service if I do not know what system I have?
Yes. Describe the problem and your home. A photo of an accessible label can help, but you do not need a model number or a diagnosis before contacting Airplex.
Does an uncomfortable room mean I need a new system?
No. Airflow, controls and the way the room gains or loses heat can all affect comfort. The cause should be checked before choosing a replacement.
Is maintenance the same as a repair?
No. Maintenance is planned care for the system. Repair addresses a fault. Mention an active problem when requesting a visit so it is not mistaken for routine maintenance.
Can you help with HVAC in an apartment?
Contact us with the problem and the building location. If the equipment is shared or belongs to the landlord, the owner or building manager may need to arrange the work.
Can a heat pump provide heating and cooling?
Yes. A heat pump can move heat into or out of the home. Whether a particular system is suitable depends on the equipment, the rooms served and the installation.
What if I want to improve only one room?
Explain how you use the room and when it is uncomfortable. The next step is to determine whether the existing system can serve it properly, whether a fault is involved or whether an addition should be considered. A room-specific problem does not automatically require whole-home replacement.
Can a new heating or cooling system use my existing ducts?
Possibly. Their condition, layout and ability to deliver the required air need to be reviewed with the proposed equipment. A new unit does not automatically correct a poorly served room. The installation proposal should identify which ducts remain and what changes are needed for the intended result.
