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.

They responded quickly to my emergency service call and sent Dennis Parker the same day. He was pleasant to work with and explained my options well. Once the extent of the problem was understood, I asked him to only do the necessary work for now. He responded with a short term plan that gave me what I needed. I will ask for him in the future, to complete the work, and for other service calls.

2026/may5 update: Dennis and Richard came to the rescue today and fixed a gas leak. They found the leak and also figured out how it happened in the first place and fixed that too. 2026/feb Update: Today I had an awesome plumber from Landry. Randy came out to a home we bought ten days ago. We had nothing working in the bathroom and an ancient something or other in the basement. He said 3 hours to fix the 3 things. He did it in two hours, all while answering my unending questions about my new home. 2025 update: Had Aaron out to fix out heater, he was great, he set out three options like Landry always does and gave good advice for our situation. When he changed a part he found that the old one was working good enough for an emergency and left it labeled with a date on it. He was so organized and knowledgeable. 2022:These guys fixed so much stuff I didn't know existed and brought everything up to code. They put in a new water heater that I never have to worry about and some water pressure control thingamajig and fixed the insane vent thingy the former owner of my apt made out of chimney parts.

Julian did an outstanding job replacing my old central AC with a cold-climate heat pump. He worked hard and stayed late, getting the job done in just two day. It is clear that he takes immense pride in his craftsmanship. The setup is clean, professional, and organized. Most importantly, everything works perfectly. The system is running smoothly, efficiently, and exactly as promised. Tim was also great. He help me pick the right system and guided me through the process of qualifying for the Mass Save rebate and 0% loan. I am incredibly grateful to the entire Landry team for making this such a smooth and stress free project.

I cannot say enough about Landry and their crew. Gavin, Anthony, JT, and Mike did a phenomenal job installing our mini splits. They showed up on time, stayed late, and worked clean. Unfortunately, My husband had a medical emergency while they were working and they stepped in and handled the situation until help arrived. If they didn’t step in it would’ve been so much worse. We will need our boiler and hot water tank replaced in a few months and will be calling Landry back to do the work. We now have a go to company for all of our plumbing needs!
