K4 Heating & Cooling

K4 Heating and Cooling was a life savor! Fernando and his crew were AMAZING! Our air conditioning unit gave out on the hottest day of July a few years back in the middle of our family reunion and thanks to Fernando's experience and recommendations, he upgraded our unit, and we never looked back. His price was very reasonable & competitive, and his labor was flawless. If you're looking for a heating & cooling company to help you with any upgrades or repairs, K4 Heating and Cooling is yhe only phone call you need to make, We highly recommend K4 Heating and Cooling 100%. Thank you Fernando!

Highly recommend K4 Heating and Cooling. Technician arrived on time and was very courteous provided great service. He explained everything to me in detail and made sure I was happy with the service before he left. Overall customer service , quality and value was excellent.Thank you Fernando

We were having issues with our AC not cooling and I contacted the K4 team. They immediately responded and gave me a same day appointment. Within a few hours of contacting them, they arrived and fixed our AC! Super responsive and great service.

Two months ago our AC unit broke down and 9 month pregnant; due any day. I began calling every heating and cooling company here in AV and booked appointments one after another for 3 days straight. Honestly, working with Fernando and his team was the best decision. He answered every question and concern politely & courteously. This gentleman has extensive knowledge and experience. They did a full replacement, relocated the AC unit from our back yard to one side of our home and all of this was accomplished within that same week. We received every update via text though a service software which was pretty cool. Fernando was the first man to arrive, checking our AC unit on what it needed and did the last inspection when everything was completed.
Also, our power outlets stopped working from our bathrooms and he was very kind to have them checked by an electrician at no charge. The whole team went far and beyond our expectation. Don't hesitate! Give them a call.

I will recommend K4 Heating & Cooling to all of our family, friends & will keep him in mind for future projects.

One of the best A/C contractor! Very responsive and friendly! Also very professional! Fixed my A/C wiring in less then 10 minutes! Now we finally have A/C upstairs! Thank you so much Fernando! I will be a returning customer if I ever have any more issues with my A/C or heater!

Fernando is awesome! He serviced my HVAC after 5 pm on a Saturday( same day service). He showed me what to do to try to keep my units running longer and better. He did not try to up sell me anything - he is who I will use going forward.-Troy Cassity

Very helpful and curdiest was on time fixed the problem and explained what the problem was definitely recommend them.

Came out on a Saturday early (rain delay)
swapped out a compressor & other parts, purge and full recharge. Always kept me informed on parts ordered status. Was professional from start to finish. Repair quote was almost half of other businesses. Will recommend to anyone I know.

W-A-R-N-I-N-G. Fernando (the owner of K3 Mechanical) is N-O-T the person/company you want to hire for anything. We have a number of problems with our new AC and Furnace unit and their installation, and once the money cleared their bank that they were paid, they now are not returning our calls or texts about getting the job completed the right way. We have a huge vibration inside our wall now that is keeping our young child up and is scaring him. They could care less and it's unfortunate this is how they treat customers. His technicians contradicted themselves multiple times as has Fernando (the owner of K3 Mechanical). They also scratched our new AC unit by dragging it across our new concrete and damaged the inside of our home in multiple areas. We are in the process of contacting our attorney and having a City Building Enforcement Code Inspector look over the work they did on our AC unit and Furnace.

Fernando was nice and professional. Check on my swamp cooler and advise what needed to be maintain / change and clean out. He did a great job!
