What Customers Say

“Stefan and Blaine just left my home after installing a gas water heater, a new furnace and AC. They are true, knowledgeable professionals working efficiently, educating me on my new heating and cooling equipment and answering all my questions. This company was recommended to me and now I understand why. Thank you for your expert service and helpful tips. Kudos to Matt as well for his thorough explanation of the different levels of products offered.”

- Valerie C.

“Ryan, service technician with M&K Climate Care came today and performed a yearly precision tune up on my furnace (I had them install a new furnace and air conditioner last year at this time).

Ryan did a very thorough job of going over the equipment and testing. He took the time to give me a better understanding of controlling the humidity levels in my house. Everything he did was explained (and repeated if I didn’t quite understand) to me.

I am very satisfied with the M&K and all of their people that I’ve had contact with from the initial installation to present time.”

- Wayne G.

Frequently Asked Questions

With proper installation, your air conditioner should last at least 8 to 15 years. If you take care of it by scheduling regular maintenance, it may last even longer. Without proper installation, care, and maintenance, you may need to replace your air conditioning unit sooner than you initially planned.

Installing a new air conditioning system generally takes between 4 and 6 hours. However, it may take longer depending on the space it will be installed in, and if an old system needs to be removed.

The best way to prepare for your technician is to clear away any objects, debris, or tripping hazards from the area that your new unit will be installed. During your in-home assessment, your Right TimeTM expert will be able to give you specific instructions unique to your home.

Variation in cost and time between air conditioning installations depend on which (if any) add-on packages are chosen. More comprehensive packages include vent replacement and ductwork cleaning, which increases the overall cost and time of the installation.

You don’t need to be present for the full installation, but we recommend you are there to let us in and see us out. After the installation is finished, we will walk you through using your new system and answer any questions you may have.
