Emergency Heater Repair and Replacement in Waltham, Massachusetts

Our expert technicians provide comprehensive air conditioning solutions, from emergency AC repair to routine maintenance and new system installations.

Emergency AC Repair in Waltham, Massachusetts

When your air conditioner breaks down on a sweltering summer day, it’s more than an inconvenience; it’s an emergency. At Landry Mechanical Inc Plumbing HVAC & Electric, we consider several situations as AC emergencies:

  • Complete system failure: If your AC won’t turn on or shuts off unexpectedly and won’t restart, you’re facing a critical issue that requires immediate attention.
  • Unusual noises or smells from your unit: Grinding, screeching, or banging sounds could indicate serious mechanical problems. Burning smells signal electrical issues, while musty odors may mean mold growth.
  • Water leaking from your AC: Excess water around your indoor unit can cause property damage and create unsafe electrical conditions.
  • Warm air blowing instead of cool: If your AC is running but not cooling, it could be due to refrigerant leaks, compressor issues, or frozen evaporator coils.

Don’t suffer through the heat. Our emergency AC repair experts are available 24/7 to restore your comfort quickly. We are the area’s largest privately owned HVAC business, so we have the resources and expertise to handle any air conditioning crisis with efficient Waltham cooling services.

Ductless Mini-Split Services in Greater Boston

Ductless mini-split systems are an excellent cooling solution for homes without existing ductwork. Here’s how they work:

  • An outdoor compressor connects to one or more indoor air handlers.
  • Refrigerant lines run between the units, eliminating any need for bulky ducts.
  • Each indoor unit can be controlled independently, allowing for zoned cooling.

We excel in ductless mini-split installations throughout Greater Boston. Our true multi-trade expertise means we can handle every aspect of your installation, from electrical work to final system setup.

Don’t let the Waltham heat get you down. Call Landry Mechanical Inc Plumbing HVAC & Electric at 508-987-0080 to discuss all your cooling needs in Waltham, MA, and how we can meet them. Trust our family-owned and -operated business to keep you comfortable with our Waltham cooling services.

Knowledge technicians that gave me options on what to do to repair my water pressure. They fixed the problem and my water pressure is now flowing properly.

Drew/Andrew came to our home to do the regular check-up of our mini-splits. We found him to be very knowledgeable about such systems. He did a fine job of inspecting, cleaning, and lubricating them, and he also gave us a lot of good information about both the condition of another much older one we have on our property and what our options could be in dealing with it if it eventually fails. And he came to our house a second day, to complete a good inspection of that mini-split. In addition to being very knowledgeable, we found Drew to be very considerate and easy to talk with. And we give a lot of credit to Landry Mechanical's service program. Another 5 star rating from us for Landry service.

Samyson was an absolute superstar - after being without hot water for a few days, he swooped in to save the day (and wouldn't quit when faced with a bit of rust/bolts that refused to budge!) Highly recommended and our dogs loved that he would throw a ball for them anytime he had to go back to his van

I recently had some electrical work done, as well as all of the smoke detectors. Everything went well, then a few weeks later they started going off on the second floor. I called and they sent someone right away. It was a defective alarm. Thank you Landry for sending someone right away.

5 stars to Landry Mechanical. The scheduler got me setup for service next day. I received a text message confirming I was on the schedule the morning of service. Then they sent me photos of the electricians with verified background checks that would be servicing my exhaust fan issue. Mike Dowd and Nick Chappelle were FANTASTIC and resolved my electrical issue and set me up with a new Panasonic bathroom exhaust fan which is much quieter and brighter. Mike and Nick were timely, professional, friendly and very helpful in resolving my problem and answering my questions. Great experience with Landry - thank you!
