According to the Environmental Protection Agency (EPA), geothermal systems are the most energy efficient, environmentally clean, and cost-effective space conditioning systems available today. Simply put, a geothermal system moves the heat from the earth into the building in the winter, and pulls the heat from the building and discharges it into the ground in the summer and/or is used to heat water. An underground series of pipe loops serve as a heat source in the winter and a heat sink in the summer. We will show you how to tap the earth's free underground energy treasure. Call Today!

I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

Cyprus Air installs and repairs a variety of Heating & Cooling equipment. With over 56 years of experience in the business, we also offer other home improvement and indoor comfort services such as Gas Fireplaces & Gas logs, and Duct Cleaning. With so many years of design, and installations in Northern Virginia, DC and Maryland, Cyprus Air offers its service oriented expertise and reliability to ensure the high quality standards that architects, engineers, and homeowners have come to rely on from one of the industry leaders.

"I begin this review by saying that I do not know the ins and outs of this company’s day-to-day doings, nor do I feel that this has been the operations of this company from its start. I choose to write this as a way of providing others with my story so that they may take caution when dealing with them and so that this company can ameliorate their behavior toward their customers. My journey began in October of 2021 when my husband and I decided to place a gas insert in our traditional open fireplace. I went online and found Cyprus Air. They came to our home and did a quote with us, which we accepted. The goal was to have the fireplace inserted in before Christmas. The first step was a gas line to the fireplace. This was the beginning of the continuous problems that would develop for three years. We had multiple issues with the gas line, multiple technicians sent to our home, and had numerous inspections by Fairfax County fail before they finally sent out their “go-to” guy, who managed to fix the problem, leading to us finally passing the inspection on March 11th of 2022. Let me also note, that I made numerous calls to Cyprus Air during this time frame always with a promise of a return call, that NEVER came. I even walked into their showroom in Springfield to get answers after not being able to get anyone to answer my calls. I spoke with a supposed manager over the phone at some point, who also did not return the calls he made promised to do. I then asked to speak to someone higher, which, as far as I know, I did. That was when their “go-to” guy was finally dispatched. This “higher up” gentleman promised to follow up to ensure all went well. I never heard from him either. During the October to March timeframe, the technicians that were dispatched to our address were unprepared, in terms of supplies. They asked us for paper towels and a ladder at one point. The ladder, which was wooden, they managed to break; I contacted the “manager” who informed me he would look into what he could do to remedy the situation. Nothing was done. Also, during this time, we were being charged for a service contract that we signed up for but had no fireplace to service. When asked, we were told that they would take the charges off the back end. This will come into play later in this story. Also, when they finally did install the fireplace and were removing the boxes from the garage to dispose of, they took a large wall hanging that was still in its box that had just been purchased. This was also mentioned to Cyprus without any resolution. Finally, in May the fireplace was fully installed and ready to go, just in time for summer. We utilized it in the winter of 2022 and in March of 2023, we made our first service call, just to ensure everything was working properly. They came out did a bit of cleaning and left, however, they did not note that there were lightbulbs that were not working. So, we contacted Cyprus Air to let them know this had been missed. They then sent out another technician, who took note of the bulbs and stated that he would place the order, and someone would be in contact to schedule another visit once they came in. We never heard from Cyprus, and we waited for a very long time (mostly because we were tired of making calls). We finally called to check the status of the bulbs (about 6 months later) to be told they had no record of the order and would need to send another technician out to take a look because they didn’t know which type to order. So, the technician came out in November of 2023, took the information, and again stated he would place the order, and someone would contact us. Again, no contact. Also, as another note, the remote for our fireplace magically disappeared after this service call. When I called Cyprus and mentioned that I thought the technician had taken it, but wasn’t 100% sure, they informed me that it would be another service call and $500 to replace the remote. At the beginning of February, I was done dealing with this company, so we called to request the service contract be terminated. Please note, that we signed a one-year service contract and were told it would go month to month after the year and we could cancel at any time. When we called, we were told that they were not sure they could cancel and that there may be additional charges, but that someone would contact us about this. Again, no contact, however, they did set up a service call for us and had someone show up at our home on February 21, 2024. We were unaware of this service call until the day of. No one was at the home upon the technician’s arrival. I contacted Cyprus via the text they sent regarding the service call and stated: “Didn’t schedule service. Asked for a service contract to be terminated.” For which I received the following reply: “ok, sent an email to cancel”. The next day I received the following reply to my cancellation “Good morning, this is Kimberly with Cyprus Air Heating & Cooling contacting you in regards to your request to cancel your maintenance contract. There are 3 more payments due in order to cancel in the of $120. I can charge the card on file for the final 3 payments to complete the 12-month contract and cancel. Please either respond to this text or give us a call at 571-367-9600. Thank you.” I then replied with: “We have had it for well over a year and were told we could cancel anytime after August of 2023. Very confused.” For which the following reply was received: “No ma’am, the contract is 12 months per visit. You had 2 visits with us and made 21 payments, resulting in 3 more payments due. It is a 12-month period per visit. Once you have another visit it renews for another 12 months. This is all stated in the contract you signed.” Needless to say, my reply was friendly back, as I reminded them that we only ever had one service call, but that things were not completed, and to this day had still not been fixed. I also mentioned that I had been trying to get out from “underneath” them and did not trust anything. I insisted that they cancel the contract, and NOT charge me the $120. I may or may not have mentioned getting Lawyers involved at this point also. The reply I received was priceless: “That is fine, the account will go to collections. Thank you! There is a lot of information here, but I feel it is necessary for anyone who is truly looking to deal with this company to have the full story from a “customer”. I wish you luck!"

Heating and air conditioning services FAQs

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
