Common Types of Air Conditioners
By knowing which type of air conditionerunit you have, you'll feel more empowered in your company search. Dundalk HVAC contractors have experience with different AC makes and models, and they can customize their skills to your needs.
- Central AC: These are the most common residential AC systems, 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.
- Portable air conditioners: As the name implies, portable AC 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 popular for apartments, condos, or individual rooms.
- Ductless mini-split: Ductless mini-split ACs have an outdoor unit and multiple interior units, with no ductwork required. They offer higher energy efficiency, flexible installation options, and individual room temperature control.
- Window-mounted ACs: Window air conditioners are a popular choice for Dundalk 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-mounted AC users set up their units without professional assistance, though technicians can still help with maintenance and repairs.
- Split ACs: Split ACs have two main elements: one inside and one outside. They provide silent operation, improved energy efficiency, ductwork options, and more cooling capability versus mini-splits.
How to Choose Your Dundalk AC Repair Service
While you might want to resolve your AC issue quickly, you should do your research before signing a contract with a repair service. Take the following steps to ensure you find the most reliable company for your home.
Confirm the Company Is Properly Licensed and Insured
Maryland HVAC contractors need licensure from the Board of Heating, Ventilation, Air Conditioning and Refrigeration (HVACR) Contractors. A master license requires three years of journeyman experience, 1,875 hours of HVAC work performed in the last year, and a comprehensive trade exam.
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 something gets damaged during work.
Read Customer Reviews
Check customer reviews on the Better Business Bureau (BBB) website for each company you're interested in. The BBB recognizes businesses that handle 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 business if most reviewers had subpar experiences.
Compare Estimates
We suggest getting contacting at least three different companies to find the best value. Get a written copy of each quote, and learn more about installer guarantees, manufacturer warranties, permitting fees and emergency repair availability.
