We signed and almost immediately formally cancelled our potential contract with Cypress Air. They are almost never available and our large deposit, which was cancelled immediately with no services performed, is still in limbo for over two weeks. These guys are in way over their heads with financial operations, customer service, and technical work. Filing complaint with BBB and will get the fraud division of our bank on their case to get our money back.

Look elsewhere and never ever sign anything with these folks. I'm changing our credit card after seeing they're billing customers for service work for units that were never installed. There are bad actors out there looking for suckers who might call Cyprus Air heating and Cooling. Take this note when you file your legal work. Virginia Code 59.1-335.9. Virginia BBB site: https://www.bbb.org/us/va/alexandria Go for it because Cyprus will not resolve this on their own,

Beware! This company is terrible. I scheduled an appointment for a free estimate on a new A/C unit. The tech was supposed to arrive between 5-6. They never showed. I called twice and received two messages from their answering service that the tech was on the way. Time passed and I received no call from the business regarding the status of the technician nor did they call the next day to apologize.

Customer service is nonexistent. You don't get to speak to anyone at the business. You communicate through the answering service. Very impersonal. If you can, find another HVAC company to service your A/C needs.

Avoid Cyprus at all costs. It has been a nightmare dealing with them. Unmet deadlines. Lousy communication. Go elsewhere!

We paid to renovate two fireplaces. Remove gas boxes and install gas burners and ceramic logs. First use with flue OPEN. Smoked brick front. Multiple service calls and always they called back to cancel. Not your usual honest hardworking Greeks.

We bought a Large Big Green Egg with all fees to the tune of just over $1200. Delivery was changed 3 times. My husband took a whole day off 3 days ago to wait for them. The even called to confirm the appt after it being changed THREE times. No show. After and calling and speaking to Sharon (manager), the delivery finally occurred on the ORIGINAL today. After paying $150 for delivery and installation, (when it's FREE delivery UNLESS you need assembly (which it turns out we really didn't) and it turned out to be one guy in an unmarked pickup dropping the egg into the existing hole, essentially, I feel really ripped off.after THREE delivery time changes.

I paid over $1200 for a new Big Green Egg. I would have REALLY expected much better service. Oh, and try to go ahead and call the delivery contractor. Took me FOUR times to get a real person instead of a "We're busy. Call back later", or, "the best way to reach us is to email." UNBELIEVABLE. Had it NOT BEEN for Sharon at Cyprus Air, I would have moved on and gone to another distributor. GOOD LUCK.

Henry is very approachable and knows his job! He showed up on time and the installation went without a glitch. He answered all my questions and made sure everything was spotless before leaving. I would highly recommend him for your HVAC installation. Services: Heating system installation, Install AC, Install thermostat
