 Trustindex verifies that the original source of the review is Google. My maintenance checkup was done on time as scheduled. George was extremely thorough, checking the system and was kind enough to look around as to why I had so much dust. He did find the problem, I believe!   Thank you for your respect of my home and my pets and your thorough checkup of both units, AC and heat systems.

They were both very knowledgeable, professional and explained what they were going to do during the inspection. They kept me informed on any issues they found and what their recommendations were.
Very pleased with the service they provided. Excellent service!!

Why Air Conditioning System Service & Maintenance Matters

Most air conditioning systems are not in the front of homeowners’ or business owners’ minds until they stop working. In addition, regular maintenance is forgotten many times. Proper air conditioning system maintenance and repair have numerous benefits that can have drastic consequences on your air conditioning system and your wallet.

Here are the advantages of regularly scheduled air conditioning system maintenance:

Increased system lifespan (often as much as 3-5 years)
The lowered risk of breakdowns/problems
Decreased energy bills
Improved energy efficiency
Reduced risk of AC emergencies
Keep your warranty in good standing

Air conditioning system maintenance and tune-ups can save you money, time, and unwanted stress. At Doctor Cool, we recommend having your air conditioning system serviced twice a year. Once in the Spring to prepare for the harsh summer months, and once in the Fall to get it winterized.

What does an air conditioning system repair tune-up service include?

Our NATE® certified technicians perform a full system air conditioning system inspection to ensure that all components of your air conditioning system is working perfectly. Doctor Cool wants to make sure that your air conditioning system provides a comfortable environment all year long.
