M&K Heating & Air: Your Dayton Ohio HVAC Experts

When your heater quits on a cold Dayton night or your AC struggles in a humid Ohio summer, you need a local team you can trust. M&K Heating & Air is a family-owned heating and cooling company serving Dayton Ohio and the surrounding communities. They focus on honest, affordable repairs and installations for your home.

Owners Michael and Kaitlyn Depoyster run the company together. They are available for emergency service calls. Their team is small and dedicated, focusing mainly on residential customers. They know how important a working HVAC system is for your family's comfort and safety.

Key HVAC Services for Dayton Homes

M&K Heating & Air handles all the common heating and cooling needs for local homeowners and businesses. They break their work into three main areas.

  • HVAC Installation or Replacement: Whether you're building new, upgrading an old system, or need a full unit swap, they handle it. They help you choose the right system for your Dayton-area home's size and layout.
  • HVAC System Repair: From strange noises and weak airflow to a system that won't turn on, they diagnose and fix it. They keep common parts on their trucks to solve many problems in one visit.
  • HVAC System Maintenance: Regular check-ups can prevent big problems. Their maintenance service helps your system run efficiently, which can lower your energy bills, especially during our hot summers and chilly winters.

Areas Served in the Greater Dayton Region

M&K Heating & Air proudly serves a wide area around Dayton Ohio. Their service towns include Kettering, Beavercreek, Trotwood, Centerville, Miamisburg, Springboro, West Carrollton, Franklin, Oakwood, German Township, Bellbrook, Moraine, Germantown, Clearcreek, Lanier, Drexel, Five Points, and Carlisle.

Knowing the local area helps them work better. They understand the common HVAC setups in older Dayton neighborhoods and newer suburban homes. This local knowledge means they can often spot issues faster and recommend solutions that work well for our specific climate.

Company History: Built on a Promise

The story of M&K Heating & Air started with a simple idea: help people without charging too much. Owner Michael Depoyster worked in the HVAC industry since 2018. He saw companies put high prices ahead of helping customers. It bothered him when people couldn't afford a needed repair.

He decided to make a change. In January 2023, he and his wife Kaitlyn started M&K Heating & Air. They wanted to provide reliable heating and cooling service at a price Dayton area families could manage. They grew from just the two of them into a small, trusted local team.

Leadership with Local Heart

Michael is the head of service, bringing his hands-on repair experience since 2018 to every job. He loves solving problems and making sure homes are comfortable. Kaitlyn manages the office, scheduling appointments and talking with customers. Having both owners involved daily means decisions are made quickly and with your needs in mind.

They live and work in the Dayton Ohio area. You're not just a job number to them; you're a neighbor. Their goal is to build long-term relationships, not just make a quick sale.

What Makes M&K Heating & Air Stand Out

Several things set this Dayton Ohio company apart from bigger corporations.

  • Family-Owned & Operated: You speak directly with the owners. This means better communication and personal accountability.
  • Upfront Pricing: They explain the cost before any work begins. No surprise fees or pressure to buy things you don't need.
  • Do It Right the First Time: Their focus is on quality repairs and installations so you don't have to call back for the same issue.
  • Customer Happiness is the Goal: Their motto is "Your family, your life, our priority." They measure success by your satisfaction.
