"Presidential customer for 25 years! I'm a family man and home is heaven. My wife and I just replaced one of three HVAC units in our home. The entire Presidential team helped us like family: selecting the right system, applying a whole bunch of discounts, choosing from amazing warranties, finalizing payment on a great price, immediately scheduling, and today removing the old system and installing a new system. And absolutely and completely clean and without damage to walls and floors! So easy! Thoughtful service."

"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"I had the best experience with Hecomo Heating & Cooling. My house's AC/heating system stopped working all of the sudden and the temperatures at the time were 90 degrees and up. I was desperate looking into many different companies. Many of them, came over to my house and did estimates at ridiculously high prices. Luckily, I found Hecomo. They came to my house, did an estimate and were ready to install my AC/heating unit very quickly and at a good price. Also, the customer service was great. They were there for me throughout the whole process. They explained to me everything that I needed to know about the system and the features. Everything is very modern and updated. I am very happy I found Hecomo."

"Everything went great. My AC died and it was close to 20 years old so I wanted the whole unit replaced. I have 4 young kids so no AC in the summer was not a pleasant option. The owner came out on site the day we called and was able to have the new unit installed the next day. I have dealt with many HVAC companies in the past as an Insurance Adjuster. These guys exceeded my expectations and were very reasonable on price. I highly recommend using Buric Heating and Air Conditioning!"

FAQs for window a/c unit service or relocation projects in Gaithersburg, 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.
