I have used CVC HVAC / Carlos for several projects around my home. Before last summer he came out and serviced my air conditioning unit and found that although the unit is older it was in good working condition. He had to replace a part and the unit has run fine since.
I have also used their services to replace old electrical boxes in the ceiling of the second floor bedrooms so I was able to replace the light fixtures with ceiling fans. He also ran the electrical for my microwave and installed the unit.
As of recent, he installed a whole house air purification unit to assist with odor elimination and remove particles from the air. The unit works great. My wife has terrible alergies and since installing the unit it has eliminated her having to take as many medications.
Today he evaluated my furnace to ensure that the water was flowing from the furnace to the drain. He cleaned the line, removed a pump that was not needed, and installed drainage.
With every project Carlos has operated with honesty and integrity, provided very competitive pricing, and completed each project without any issues. If you require any electrical or HVAC work to be completed, I would highly recommend that you call Carlos with CVC HVAC. He has been great with every project he has completed in our home.

Our furnace went out the day before Thanksgiving. On Friday we called CVCHvac at 8am and Carlos was at our house by 9:30. He made a diagnosis and offered us a great deal on a new furnace and thermostat. He and his wife came the following Tuesday and installed the new furnace and cleaned up nicely afterward. He made several helpful suggestions and sent us the warrantee in good time. We are delighted and recommend him very highly.

I am thoroughly impressed with this company. On a SUNDAY, they came all the way to my apartment and they fixed the leak and filled up my Freon within an hour. They did a quick and reliable job and explained everything to me. 10 stars
