Keep your HVAC system healthy with preventative maintenance

Like any household appliance, HVAC systems must be maintained regularly to operate efficiently. So if you want to help prolong the lifespan of your AC or furnace, reduce your risk of unexpected and expensive repairs, and keep your energy bills low, call Michael & Son today. During your tune-up, one of our NATE-certified techs will thoroughly inspect your system, check all wiring and connections, and confirm your HVAC system is working properly. They'll also provide a written report with recommendations on ensuring your system continues to operate at optimum performance.

The weather in Baltimore is hot and muggy in the summer–and cold, overcast, and cloudy in the winter. That's why ensuring your air conditioner and furnace are working properly is vital. With over 40 years in the industry, we’re the most dependable company in Baltimore!

5 Simple Steps To Your Baltimore HVAC Tune‑Up

  1. Schedule your tune-up

    Call us at (410) 929-7190 or schedule online, and one of our customer service reps will book you a service appointment ASAP. We consistently work to accommodate even the busiest of schedules.

  2. Get to know your technician

    The day before your tune-up technician arrives, you'll receive an email with your technician's photo, bio, relevant trade licenses, and fun background information. We always send a little information about our technicians beforehand, so our customers feel comfortable with who will work in their Baltimore homes.

  3. We check & clean your HVAC system

    Our technicians always arrive on time, ready to inspect and clean your HVAC system. Our technicians will always wear protective shoe covers in your home and lay down spotless drop covers to protect the workspace and keep your home clean.

  4. Get a written report on your system

    After the tune-up, our technicians will provide you with a written report detailing any additional work your AC or heating system may need now to prevent repairs later. After explaining any immediate repair needs, you can choose what work you'd like to prioritize. We'll either complete the work in the same visit or schedule another time/day to return and get the job done.

  5. Tell us how we did

    If there is anything we could have done better during your HVAC maintenance appointment, we want to know about it. Our team will be in touch with you to see how every aspect of the tune-up went. If you're not satisfied for any reason, we'll make it right.
