This Old House empowers homeowners with the knowledge and tools they need to tackle various projects and navigate the complexities of homeownership.

Common Types of Air Conditioners

By knowing which type of air conditioner you have, you'll feel more confident in your provider search. Chelmsford HVAC technicians have experience with different AC makes and models, and they can adapt their skills to your needs.

  • Window ACs: Window air conditioners are a popular choice for Chelmsford apartments, condos, and townhomes. These compact, affordable 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 set up their units without professional assistance, though technicians can still help with maintenance and repairs.
  • 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 different rooms in your home.
  • Split ACs: Split ACs have two main elements: one inside and one outside. They offer peaceful operation, enhanced efficiency, ductwork options, and more cooling capability versus mini-splits.
  • Ductless mini-split: Ductless mini-splits have an outdoor unit and one or more indoor units, with no ductwork required. They offer individual room temperature control, higher energy efficiency, and flexible installation options.
  • Portable air conditioners: As the name suggests, 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.

How to Choose Your Chelmsford AC Repair Service

While you might want to resolve your AC issue quickly, you should do some essential research before hiring a repair service. Take the following steps to ensure you find the top-rated 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.

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 accidents happen 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 contractors that resolve complaints professionally and honor their warranties.

It's common for even the best AC repair companies 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 emergency repair availability, permitting fees, manufacturer warranties and installer guarantees.

Frequently Asked Questions About AC Repair in Chelmsford

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

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$68–$181
Electrical circuits$200–$250
Drainage problems$100–$150
Thermostat$91–$227
Refrigerant leak$400–$1500
Frozen condenser coils$1,360–$4,080
Fan or air blower issues$150–$200
Compressor replacement$600–$1,723

What month is best for getting an air conditioner replaced?

The best time to replace HVAC systems is during the off-season, when there's less demand for HVAC technicians and costs are cheaper. With Chelmsford's weather patterns, this is usually between late September and the middle of November or early March to mid-May.

What do I do if my AC is running but not cooling?

If your AC is running but not cooling, a blocked condenser coil could be the culprit. Normally, the AC’s condenser fan pulls air into the outdoor unit through the condenser coil to extract heat energy from your home. A technician can help by clearing the clog or replacing a faulty coil.

Should my HVAC company have a private accreditation?

Private accreditations might not be required, but contractors that seek them are typically more trustworthy. The two largest HVAC trade bodies that issue certifications are the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and Air Conditioning Contractors of America (ACCA).

How quickly can an HVAC company in Chelmsford respond to emergency repair requests?

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