Best Air Conditioner Installation in Plano TX

I find this Devard's heat air electric & plumbing company on next door, going by the reviews I contact them and tell them about a house I purchased and its AC system needs the annual preventative maintenance plus flushing its drainage pipe/s making sure its not clogged as the house inspector noted.
I call them and explain all this to the lady who answered, she asks me to send them the inspector notes for them to see so they know what they need and what to do when on site, and I send them these inspector notes from the report itself, by now 3 days already passed, I do not hear from them, I call again and the lady answers telling me she needs to speak to the “manager” (so looks like the lady cannot do any scheduling unless go through the manager, a bit weird but whatever) a day or two passes by, I call and lady goes: the manager said he needs to the full house inspector report, and I go I have sent you all the notes related to the HVAC, why the manager wants to see the full report which got nothing to do with the HVAC, what the manager got to do with seeing the full report.
2 or 3 days go by till the lady calls and leaves a message about me being blessed since the manager agreed for the lady to go ahead and put me on their service schedule, when I decided I am not using this company.
They wasted around 10 days of my time and my need, I think greedy companies nowadays they only want to show up at your doorstep to change the AC unit for 15K and do not want to service them for $100, companies and people not looking further than their nose tip and not thinking about their kids future which going to pay for this greediness.

If u want it done right this is who u call

No one wants to find a natural gas leak but when you do, you need expert help fast!! I called Billy Go and they responded promptly to give us a fair estimate of the work to replace the gas lines from the meter and go under the house to connect to all 3 gas appliances!! The city inspector promptly approved the work they did and they cleaned up the work area properly. BILLY GO, the Landlord, and the City all worked together to get us back online with Service. Especially Thank you Marco!

So, let me tell you , I never leave review but this time I must. I have to say it's been a long time since I have seen great service. This company is honest and reliable. They fixed my HVAC the right the first time .

I take reviews very seriously, when I saw the reviews , I could not believe it. So I decided to give it a try. Let me tell you WOW !!!

This will be my go to company for all my future HVAC needs.
