Start Your Replacement Off Right with a Free Estimate

If your current AC is 10-15+ years old, doesn’t keep you cool, or continuously breaks down, you’re better off upgrading to a new AC system. That said, we know it can sometimes be difficult to decide whether to repair or replace your system. So, if you’re on the fence, here are some key benefits of a new AC installation to keep in mind:

  • Lower Energy Bills: Due to their higher efficiency, new AC units use less energy to cool your home, saving you money on utility bills.
  • Better Cooling Performance: New AC systems provide better and more consistent cooling, which helps you avoid hot and cold spots in your home.
  • Reduced Repair Costs: Tired of sinking money into AC repairs? Installing a new system reduces the chance of breakdowns, saving you money on repairs.
  • Improved Indoor Air Quality: New AC systems often come with better air filtration, which can help remove pollutants and allergens from the air.
  • Warranty Protection: A new AC means a new warranty! This can provide peace of mind, knowing that replacement parts or unexpected repairs are covered for a certain period after installation.
  • Quieter Operation: New AC units are built to run quietly so they don’t disturb your peace. This is great for homes and especially for businesses needing a quiet space.

See what happy customers are saying about RCM

“I am so happy with everything words can’t convey them all…”

“I want to personally thank Randy and Christian from RCM Heating and Cooling for their professionalism. I had to replace my old air conditioning and heating unit because of a failed condenser and age. Randy and Christian arrived early and stayed late doing an excellent job. I live on the second floor of an old condo building and each unit has its own little closet for air, heat, and water. This area is so small that only one person can barely move. Because this place was so small it took them longer to install them. They didn’t complain and both worked effortlessly putting in both units. I am so happy with everything words can’t convey them all.

If you are in need of a company with excellent service, contact RCM Heating and Cooling. Chris is a female owner/operator with over 20 years in HVAC service and I would recommend her company every time. Thank you all, really appreciate it.”
