"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. 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"

"Needed a complete service on my furnace and A/C system prior to putting my house on the market in a few weeks. Magna Tech Temp Air did a terrific job at a very reasonable price. Showed up on time and got the job done right. Great customer service, good communication, overall great experience. Wore shoe covers to protect my flooring. Shout out to Albert, he even went above and beyond to help me with opening the indoor valves on my outside water spigots because I couldn’t reach them at 9 months pregnant. Definitely recommend this company. I feel confident knowing that when the home inspector visits my house pre-sale, my HVAC system will pass with flying colors."

"Overall McCrea did a good job with my Sept 23, 2019, HVAC installation. The POSITIVES significantly outweigh the negatives: · They had the best price out of 6 proposals. · They agreed to add an additional HVAC return to the basement free of charge ($250). · They leveled my second old existing heat pump without asking...free of charge…I really liked that. · They told me that Fairfax county does a free inspection upon request. I’ve never had an installer tell me this…it is not in their interest to do so. The county inspection was primarily electrical but it was good to have even that independently reviewed. · They responded within 2 hours after I called about an installation problem. It turned out a condensate PVC pipe was installed wrong and tripped a cutoff switch. Everyone makes mistakes. I give them credit on this one because they responded quickly and repaired it quickly. · I requested a Trane and NATE certified installer and McCrea sent out Greg Dworchak who, along with 2 others did an excellent job. They were competent and friendly and answered all my questions very well. One NEGATIVE: · I liked the first sales person (Kris Kimmmel) who gave the initial proposal...very professional and friendly. My only concern was that he went on vacation and the follow up was slow. He did tell me he would be on vacation with limited email access. I emailed my intention to move forward on the proposal by the required date but the response was too late to get the significant Trane rebate. Weeks later I received a call from another representative (Chris Aiani) and he provided an acceptable proposal although it was a lower SEER unit (XR14) instead of the XR16i I originally wanted. Chris apologized to me about this and said they were re-organizing to provide more sales support and that this should not happen again."

"VS earned my trust and confidence and is now on my "use in the future list"! He was on time, professional and best of all, made only the repairs needed at a less than expected price. Over the years I have used a number of different HVAC repair services but I will say, VS has been the best. Highly recommended!!"

"Technicians were on time and very courteous.  They thoroughly inspected and cleaned my 15 yr old air conditioner and changed my air filter as advertised.  Although they indicated that the system was nearing the end of its life due to high readings for volts, and strain on the motor, etc., they did not pressure me to unnecessarily replace parts at this time.  They did provide me with a few options for repairing or replacing the system in the future should it fail, all without the high pressure attempt to sell me more than I need at the moment (something I hate). I would definitely recommend both the company and technicians to others."

Heating and Air Conditioning FAQs, answered by experts

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

HVAC companies may charge an hourly rate or a flat fee. Hourly rates typically range from $100 to $250 per hour, with an average around $175. Some contractors charge a flat fee for specific services, such as an inspection, which can cost between $150 and $500. The total cost of an HVAC service is influenced by several factors, including: the urgency of the service (emergency repairs after hours or on holidays cost more), the time of year, the type, size, and brand of your HVAC system, the specific repair needed, and whether you have a service contract.
