Heating Repair, Maintenance & Installation. From an emergency no-heat call to a fall tune-up that keeps your furnace running safely all winter, our team keeps Metro East homes warm. We repair and maintain furnaces, perform seasonal clean-and-checks, and install new, efficient heating systems when it’s time to replace.
Air Conditioning Repair, Maintenance & Installation. Metro East summers are hot and humid — a working AC isn’t a luxury. Crumer’s repairs failing systems, provides spring tune-ups and seasonal clean-and-checks, installs ductless mini-splits, and puts in new air conditioners sized right for your home.
Handyman & Home Repair Services. Beyond heating and cooling, our handymen knock out the household to-do list — drywall and painting, doors and hardware, electrical, plumbing, water heaters, decks, and more.

Decided to give this company a call after my AC went out, and I am so glad I did! Larry came out that very day, accessed the unit, told me what the problem was and how much it would cost to repair. He even advised me to get other quotes, of which I did and was totally shocked at the price difference! He came by the next day to complete the job, and was so thorough he discovered another problem of which he quickly fixed. And was still hundreds cheaper than the other 2 companies for just the 1 problem! Expertise and professionalism at its best! I will not be using any other Company! Thank you Crumer's Heating & Cooling! An A+ company!
