Removed AC unit from Garden
Khadija L.

John is amazing! He came in to check the flow of a new AC unit in my home. He could have just charged and checked the vents, but no! That is not John! He cares beyond words...He checked my AC unit installation. He gave me a list of things that needed to be addressed and corrected. He spent a great deal of time in each room and in the Attic. I learned a lot with him and I knew he was going to be my main AC person. I just called him recently to relocate my AC unit for installation of pavers in garden. He came and he did his magic! I am hiring him next to add an AC unit to my garage! I trust John. He is a perfectionist and I trust his expertise, professionalism, and true love for what he does and the people he helps. He is very reasonable and you will be smiling when he works on your project! I highly recommend him

Core is the answer to your Heating & A/C needs. John is professional, dependable, honest & has the experience to repair! Hands down the very best around! He repaired a furnace that I was told needed to be replaced & it works better than ever! I can't explain how happy I am to have found such an honest & awesome technician. Excellent service & everyone I have recommended this company to is more than satisfied! Thanks John for being awesome!

John made my day again today. Last summer he came over to check off our A/C system with affordable and honest servive. This time he came on a Sunday afternoon to replace our gas cooktop. Besides his professional knowledge in heating and air-conditioning, John is also very good at computer and high tech gadgets, for our new cooktop is with wifi and bluetooth. We will definitely recommend John to our friends. Thank you, John, for your professional and first class service!

John from Core putting the finishing touches on the whole house fan blade.

Late to review but we've had a great experience with Reyes Heating & Air -- first to install our…read morezoned HVAC, and then for subsequent service visits. We found their prices to be reasonable. More importantly, Udiel (the owner) and his team are all responsive, friendly and helpful. When our heating system broke down over the holidays, they still were able to have a guy come out on Dec 26 (despite being closed) to identify the issue and order us a replacement part. He told us what needed to be done to prevent it from happening again -- essentially the crazy winds knocked the cover off a unit off roof loose and water got in. They managed to secure us a part quickly and replaced in before we had friends come over for New Years Eve. So grateful for their help during the holidays. Cannot recommend Reyes enough!

I wholeheartedly recommend Reyes Heating and Air for HVAC work. Our furnace stopped working 3 weeks…read moreago on a Thursday afternoon. Jimmy Reyes arrived at 8am Friday morning to take a look and told us they could fix the furnace, but since it was old there was a possibility something else would fail in the future. We had installed the furnace and A/C condenser together in 2002 and decided the best course of action would be to replace both. Jimmy told us that the A/C unit would require a permit and that might slow down installation, and provided a competitive estimate. Fortunately, we were leaving for a week's vacation the following day but Reyes dropped off some space heaters to keep us warm in the meantime. A week later, Reyes arrived promptly at 8am to install the new furnace and A/C (having secured the permit). The team introduced themselves (so polite!) and placed tarps, etc. to protect our flooring. They worked diligently and completed the entire job in 2 days! Not only that, but they removed the registers and sealed all the ducts to maximize the heating and cooling. We could not be happier. The new furnace and A/C are super energy efficient, quiet and effective. Reyes Heating and Air set the standard for excellence and customer service.

TL; DR: Outstanding professional work at a fair price when you need it!…read more I used this company 3 years ago to unclog my kitchen sink. (Me vs garbage disposal, guess who lost?) Fast forward to this current issue. I was frustrated getting replies of various prices or no price at all "We have to see it to give you a price" I didn't want to deal with the slow drain in my bathroom. That sink is brand new, I was so annoyed. I called Moore on the off chance they had availability. They did. Their drain unclogging price is clearly listed on their Yelp page. I respect that. Easy scheduling based on my needs and the pricing I clear, NO SURPRISES. Service provider arrived at the top of my appointment window, wore a mask, got to work. He showed us what the problem was so we could manage it ourselves should it happen again. Like I said, new sink. Like new NEW don't break by messing with it new. Now we know we won't break anything accessing it the way the service person did. I appreciate the professionalism, the mentoring, and the kindness. Bookmark this. I know you're too smart to pour chemicals down your drains to clear it, Get a professional to help and save your home pipes integrity. Fiver. Perfection. Satisfied.

We were members of this company's HVAC and plumbing maintenance program for several years. The…read moreconcept is great - but execution was consistently poor. The biggest issue: they simply could not keep appointments. Frequent no-shows, missed windows, and last-minute reschedules turned routine maintenance into a recurring hassle. The second issue: constant upselling. Nearly every visit came with a "the system is fine" but we recommend additional products or upgrades. The final incident made us cancel: They performed routine maintenance on a system that was working fine when they arrived. After the maintenance, the HVAC unit wouldn't turn on. We were told it was "about to fail" and the maintenance did not cause the failure. (Debatable.) Conveniently, they had the part on hand but would only install it if we paid out of pocket - even though the part was under warranty. (Don't worry, another company replaced the same part under warranty the following day.) I would think carefully before signing up for a membership.
