"I had an absolutely terrible experience with McRae Air Conditioning and Heating. I purchased a home equipped with their HVAC system, and within just five months, the heat stopped working—right in the middle of winter during a snowstorm. My home was freezing at 50°F, so I called for service, which should have been covered under warranty. I scheduled an appointment, and the technician, after being several hours late, went to the wrong address, left a sticker on someone else’s door, and left without even trying to contact me. When I called back, the customer service rep was rude, dismissive, and completely unhelpful. He initially told me the technician was on the way and just 12 miles away—but after another hour of waiting, I called again only to be told that the technician had already “been to my house 2 hours ago” (the wrong one) and left a note. If the rep actually wanted to help, he would have told me this during my first call instead of wasting my time and leaving me sitting in the cold. Not once did the technician call me to confirm the address or check in after knocking on the wrong door. When I expressed my frustration, the rep rudely dismissed my concerns, saying, “Well, I had nothing to do with that,” and then interrupted me with, “Do you still want to rebook or not?” as if I had to stop talking or risk not getting another appointment. This was an emergency call in the middle of winter, and McRae handled it in the most unprofessional, careless, and disappointing way possible. If you’re considering using them for HVAC service, do yourself a favor and go with another company. I’ll update this review after the (hopefully successful) service call and speaking to the manager who was not there at 4 pm on a Wednesday."

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!"

An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:
Blower door test: $350
Duct testing: $100
HERS test: $375
HERS certification: $200
Infrared imaging: $200
To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.
The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency.
A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.
Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.
The three levels of home energy audits include:
Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.
Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.
Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
