Common Types of Air Conditioners
HVAC technicians have the expertise to service most air conditioner models, but knowing more about what you have can be beneficial. Below, we'll explain each of the common AC systems.
- Window-mounted ACs: Window air conditioners are a popular choice for Cambridge townhomes, apartments, and condos. 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 AC users install their units without professional assistance, though technicians can still help with maintenance and repairs.
- Ductless mini-split: Ductless mini-split ACs have an outdoor 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 precise, consistent temperature control. They feature a central unit that cools and purifies outside air and sends it through ducts to various rooms in your home.
- Split ACs: Split AC units have two main elements: one inside and one outside. They offer quiet operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
- Portable air conditioners: As the name suggests, portable air conditioner units 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 preferred for condos, apartments, or individual rooms.
How to Choose Your Cambridge AC Repair Service
While you might want to resolve your AC issue quickly, you should do some essential research before committing to a repair service. Take the following steps to ensure you find the most suitable company for your home.
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.
Many states and cities also require companies to carry liability insurance. Even if your community doesn't require it, we still recommend choosing an insured company. This will protect you if an accident happens or something gets damaged.
Read Customer Reviews
Find customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB accredits contractors that resolve 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
Obtain at least three detailed, written estimates from different companies for the best deal. A good estimate should include additional fees such as permitting costs. You should also ask about the emergency repair process, manufacturer warranties, and installer guarantees.
