Four steps. No surprises.
Diagnose
We test the system and find the real cause, not just the symptom.
Quote & authorize
You get repair and replacement options with prices in writing. Nothing starts until you approve.
Do the work
Same-day repairs in most cases. Installs and repairs done right, with the old equipment hauled away.
Test
We measure airflow and temperatures and show you the result.
Is your AC really working?
Run the system for 15 minutes, then measure the air going into the return grille and the air coming out of the supply vent nearest the unit.
A healthy system usually drops the air temperature by about 16 to 22°F. A much smaller drop points to low refrigerant, a dirty coil, or an airflow problem. Call us and tell us your numbers.

What Dallas customers say about us
Awesome company! My 36 year old heating system finally kicked the bucket just in time for a winter blast. Shain services came out next day, system ordered and replaced immediately. Couldn’t be happier. I feel so fortunate for these guys. Very professional, communication was top notch, respected my time and my home!
I wouldn’t want anyone else doing the job but this company. my ac went out at 10pm and he was very quick to get back with me and fixed it right away. Very professional and knowledgeable.
Quick to come out late on a Sunday evening in 100+ degree heat to check out our A/C unit. Great service with greater prices 100% going to be using them again thank you again Shain Services!!!
Tech came out today (on a Sunday). Our air conditioner stopped working late last night. I called Shain's Service first thing this morning and within 2 hours my AC was up and working. I will definitely use them again in the future.
Very pleased.
Punctual, swift, very reasonable and cleaned up after.
I do recommend!!
Shain Services went above and beyond to fix my AC Unit. He made sure I had my AC fixed on a Saturday He is very knowledgeable and explained everything so I understood what needed to be repaired. I recommend him and I will use him going forward. Shain Services cares about their customers. Great Service!!
