My A/C went out and Amanda was able to find a time that worked for me to get Bob to come out and get it working.

Services: HVAC, Heating and cooling repair, A/C and Furnace Maintenance Bob and Jose are a pleasure to work with. Both are very knowledgeable and friendly. I am glad I signed up for the maintenance program to maintain my A/C and Furnace. Custom Service's prices are very reasonable for the quality of service they provide.

A few months ago, we tried out custom services heating and cooling to back up a quote that we got from the company that we used for many years. We called custom services because we didn’t like the quote that we were given buy the previous company and they had a pricing tier that made no sense with no itemization. Custom services came out, identified exactly what needed to be replaced and did it at an affordable and timely manner. They are now our go to for all of our heating and cooling needs.Posted on John ReffettTrustindex verifies that the original source of the review is Google.

Quick, Friendly.Posted on Usman AhmedTrustindex verifies that the original source of the review is Google. A reliable, fair and friendly local business. Bob was able to be onsite within hours of me calling, even on a weekend. We needed a new part, and he was able to go retrieve it before the parts store closed and bring it back for installation. A few days later, Bob came out again when things weren't working as intended, but fixed the issue and didn't charge extra. Good find, and highly recommend them.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
