"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"

"McCrea replaced a 20 year old HVAC system with a new Trane 4-ton XL16i condenser, XV80 furnace and new coils. The salesman, Mark, was very responsive to my request for quote changes or additional items, including financing options. He was very knowledgeable and patient through the entire process as I worked with other companies for competing quotes. As a result of Mark’s recommendations and excellent pricing, I added on a new Aprilaire 1210 filter box (including replacing a portion of the return duct work/box) and an Aprilaire 600M whole house humidifier. I was able to schedule install four days after signing the contract. The installers, Charles and Christian, arrived on time and removed the old and installed the new in about 7 hours. They provided an overview of system operation and cleaned up so well, you couldn’t tell that a significant installation had occurred. I would recommend McCrea, especially Mark, Charles, and Christian to anyone...they were professional and did an excellent job. My home is so much more comfortable with a system that will be better on the summer and winter utility bills."

"I couldn't be happier with the service I received from McCrea Heating and Air Conditioning Services of Maryland. Upon returning from vacation on a 100 degree July day, I found my old HVAC system basically dead (90 degrees in my kitchen!) ... Shane immediately came out to provide an estimate, we signed a contract on the spot, and he kindly provided some freon to hold me over until the new system could be installed. Brian and Nick showed up exactly on time to install the unit, used drop cloths to protect my flooring, and were exceedingly polite and professional throughout. I'd highly recommend this organization."

"If you want honest, straight-forward, complete, and competitive pricing for a new HVAC system, go to Bluestar Air Mechanical. Our 21-year old systems needed replacement and we began our quotation/search process. Amongst the 7 companies we inquired with, Bluestar had the most comprehensive explanation, set of offerings, and was patient with us as we completed our comparisons. John promptly and completely answered all of my questions ranging from installation, future usage, efficiency, and advice on what was necessary vs an accessory. Lynn at the office was prompt and courteous on all of my scheduling, dispatch, and payment inquiries. You'll get top notch quality, service, and friendliness if you work with Bluestar for your HVAC replacement needs."

"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."

"AMJ Air did an excellent job with my AC repair. The technician arrived on time, quickly diagnosed the issue, and explained everything in a clear and honest way. The repair was completed the same day, and my system has been running perfectly since. Professional, knowledgeable, and easy to work with—I highly recommend AMJ Air for any HVAC needs."

Heating and Air Conditioning questions, answered by experts

Yes, a frozen AC unit can affect your indoor air quality since the reduced airflow won't be as effective at removing air pollutants, like dust and other allergens. Additionally, ice around the unit can create excess moisture, leading to mold and mildew that can damage your home if you don’t catch it early.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.
