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 explain each of the common AC systems.
- Window ACs: Window air conditioners are a popular choice for Marlborough condos, townhomes, and apartments. These compact, affordable units are designed for cooling small spaces and single rooms, and they fit snugly in a window frame or dedicated wall slot. Many window air conditioner users install their units without professional assistance, though technicians can still help with maintenance and repairs.
- Ductless mini-split: Ductless mini-split AC units have an exterior unit and one or more indoor units, with no ductwork required. They offer flexible installation options, higher energy efficiency, and individual room temperature control.
- 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 different rooms in your home.
- 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 condos, apartments, or individual rooms.
- Split ACs: Split air conditioners have two main elements: one indoors and one outdoors. They offer peaceful operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
How to Choose Your Marlborough AC Repair Service
You likely want a swift resolution for your air conditioner's problem. However, before signing up with a repair company, it's important to do careful research to ensure it's the best for your home. Here are a few essential steps to follow.
Confirm the Company Is Properly Licensed and Insured
The Massachusetts Office of Public Safety and Inspections issues Refrigeration Technician licenses to crew members and Refrigeration Contractor licenses to business owners. Each crew member must meet specific hour requirements for training and practical experience. They must also carry a high school diploma/GED and Universal CFC certification to apply.
You should also verify a company has sufficient liability insurance coverage, even if your state doesn't require it. Choosing an insured company will protect you if mishaps arise during work.
Read Customer Reviews
Check customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits businesses that respond to complaints professionally and honor their warranties.
It's normal for even the best AC repair providers to have both positive and negative reviews. Read each one carefully, and avoid a company if most reviewers had subpar experiences.
Compare Estimates
We advise getting at least three different estimates to find the best cost and services. Get a written copy of each quote, and learn more about installer guarantees, manufacturer warranties, permitting fees and emergency repair availability.
