"Have used this company for several years; was very, very happy initially with the improvements made to the lawn and the customer service. We would often pay for the extra services as we felt they would have a positive impact on our curb appeal. In the past year, the quality of our lawn care and the way it looks has declined. We now have more weeds in our lawn than we did when we initially started using the service. We have paid for the extra weed treatments on top of the monthly treatments but there has been little to no improvement. We have asked for advice but there is clearly a frustration with us as customers that is evident. Our last email/communication has not received any response. We are now moving on to another company in the hopes our lawn will improve."

"I have been a customer for a very long time and this scheduled maintenance and dryer vent cleaning was done by Cesar. I have to say he is one very thorough technician and I was very pleased with his inspection and vent cleaning. His service was so different than some of the ones I've had before. I even had one inspector tell me he didn't need to check in my attic which houses one of our two units. Let me tell you about Cesar, he even cleaned up behind my dryer for me. This is something that is rare in customer service. I have my HVAC seasonally maintenanced and never had a inspector be as thorough as him. The pictures he took and explained to me and the one problem he found that no other inspector had found in all this time. I tried to spare him from the attic heat for the repair and have him return on another day in the morning but he didn't mind going back in there to fix the problem for us although it was in the dead heat of the day. I just hope the company sees this review and knows what a good technician they have in Cesar."

"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"

FAQs for swamp cooler service or repair projects in Frederick, MD

A well-maintained swamp cooler can last between 10 and 15 years. Its longevity depends on usage frequency, water quality, and proper care. Regular maintenance, like winterization and protective measures, can preserve your system's efficiency and prevent premature breakdowns, ensuring reliable cooling performance over its lifespan. Hiring a professional to take care of any repairs over your swamp cooler’s lifespan will ensure it’s restored to proper functioning and can help it last longer.

You should consider replacing your swamp cooler if it shows signs of severe corrosion, inadequate maintenance, advanced age, restricted airflow, or ongoing leaks. When repair costs and performance inefficiencies make restoration impractical, replacement may be the best option. Evaluating these issues with a professional ensures you choose the most effective solution, preserving comfort and cost efficiency while avoiding further deterioration of the system.
