Common Types of Air Conditioners

HVAC technicians have the expertise to service most air conditioner types, but knowing more about what you have can be beneficial. Below, we'll describe each of the common AC systems.

  • Window-mounted ACs: Window air conditioners are a popular choice for Nashua townhomes, condos, and apartments. These budget-friendly, convenient units are designed for cooling single rooms and small spaces, and they fit snugly in a window frame or dedicated wall slot. Many window-mounted AC users deploy their units without professional assistance, though technicians can still help with maintenance and repairs.
  • Ductless mini-split: Ductless mini-splits have an exterior unit and multiple interior units, with no ductwork required. They offer individual room temperature control, flexible installation options, and higher energy efficiency.
  • Split ACs: Split ACs have two main elements: one indoors and one outdoors. They offer quiet operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Portable air conditioners: As the name hints, portable ACs don't require permanent installation or ductwork. Instead, they remove hot air through an exhaust hose connected to a window or nearby vent. They're a common choice for apartments, condos, or individual rooms.
  • Central AC: These are the most common home air conditioners, offering consistent, precise temperature control. They feature a central unit that cools air from outside, purifies it, and sends it through ducts to various rooms in your home.

How to Choose Your Nashua AC Repair Service

You likely want a swift resolution for your air conditioner's problem. However, before hiring a repair company, it's important to carefully investigate how well it fits your home's needs. Here are a few essential steps to follow.

Confirm the Company Is Properly Licensed and Insured

While New Hampshire's Mechanical Safety and Licensing Board regulates some mechanical contractors at a state level, AC repair companies are regulated at the local level. We strongly encourage you to contact your city government about licensing and operational requirements.

You should also check a company has sufficient liability coverage, even if your state doesn't require it. Choosing an insured company will protect you if something gets damaged during work.

Read Customer Reviews

Find customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes contractors that respond to complaints effectively and honor their warranties.

It's normal for even the best AC repair businesses to have both positive and negative reviews. Read each one carefully, and avoid a company if most reviewers had subpar experiences.

Compare Estimates

We suggest getting at least three different estimates to find the best cost and services. Get a written copy of each quote, and learn more about permitting fees, manufacturer warranties, emergency repair availability and installer guarantees.

Frequently Asked Questions About AC Repair in Nashua

What's the cost of an AC repair job in Nashua?

Your AC repair costs will hinge on your system's make and model and the malfunctioning part. A basic repair job like sorting out a thermostat might cost $150–$250, whereas a more intricate fix like swapping out the compressor will be more expensive.

See the average costs for common AC repairs below.

Common RepairAverage Cost
Clogged air filter$66–$176
Electrical circuits$200–$250
Drainage problems$100–$150
Refrigerant leak$400–$1500
Frozen condenser coils$1,316–$3,949
Fan or air blower issues$150–$200
Compressor replacement$600–$1,667

Does my air conditioner need routine maintenance? If so, how often?

Homeowners should have their AC systems serviced every year to ensure optimal performance. This usually involves cleaning the outdoor unit of brush and debris. Regular servicing can help to maintain the system's efficiency and prolong its lifespan.

When is the best time to replace an AC unit?

To determine the best time for your installation, consider both local weather patterns and company demand. Generally, contractors are busier as the climate gets warmer and less busy during cool seasons. Therefore, it might be best to get the job done between late September and mid-November or March to mid-May.

How many years until I should replace my AC unit?

You won’t need to change air conditioner for 10–15 years with proper maintenance. As your AC grows older, its mechanical parts might become obsolete. You'll probably need to consider new AC installation if your company can't replace a broken part.

My HVAC problem is urgent. How quickly could a company respond?

The response time can vary by company, but HVAC companies strive to handle emergency repair requests as quickly as possible. Some companies offer same-day or next-day service for these issues. While a specific timeframe might be listed in your contract, contacting the provider directly is best so you can get the most accurate information.
