McCrea is a family owned business that has served our area since 1936. Financing and rebates are available on Trane systems installed by McCrea. Resistrictions apply and these are limited time offers call for details. "Its hard to stop a Trane"

"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."

"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"

"Ok, some neighbors complaint how expensive Holtzople can be, but boy, you don’t get such quality and service elsewhere. We have had them for decades and this year needed a new unit because ours was so old, and this latest model was installed in three days, right before that June heat wave hit. And you get two free inspections following installation to see that it is working optimally with the most incredible work force ever—on time, competent, polite, caring and oh so concerned that you are a satisfied customer. For our money, they don’t come any better! And you’d be amazed at the nos. of people who agree with us!"

"I called to get an inspection done on my AC unit and was quoted $90 for the inspection plus $120 an hr for ADDITIONAL hrs. I ASKED when do I know when the “additional hrs start”, He stated that the tech would let me know once the inspection was done and then at that time he would let me know if there was work that needed to be fixed or if there was nothing then the service would end and I would only have to pay the $90. They charged me $210 for the inspection. I called and requested that we both listen to the call (Because all calls are recorded) They played the call, heard what the rep said and then stated they would get back to me. When I finally reached them again (they never called me back), they stated I would not get a refund, then replayed the call cutting out the part when the rep stated clearly that the service was only $90. They not only GASLIGHTED me, but they altered the recording. $120 may not matter to most but it sure matters to me."

FAQs for window a/c unit service or relocation projects in Knoxville, MD

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
