What is the best air conditioning brand?

There are many great air conditioning manufacturers out there, but at Dial One, we recommend and install Trane air conditioners. Trane air conditioners offer cost-effective, energy-efficient cooling with corrosion-free aluminum condenser coils. Available features like two-stage cooling, variable-speed compressors, and advanced sound insulation improve comfort and efficiency.

When should I replace my AC unit?

The older an air conditioner is, the more problematic and expensive it will be to operate. You should consider installing a new system when the current air conditioner is more than 10 to 15 years old, starts requiring frequent repairs, becomes inefficient (causing your energy bills to skyrocket), and/or has major issues like a failing compressor or coil leaks.

Review of Dial One Johnson Plumbing

Kerlin and Cameron were a pleasure to work with. They were polite, respectful, worked well together and explained all options and required decisions on my part with patience. The work they did replacing our kitchen faucet was flawless and they cleaned up everything as well as I could have! I commented the water pressure with the new faucet was noticeably better, Kerlin guessed correctly that we are on Rocket water. He foresees a white ring forming on the sprayer in time, and gave me the name of a product to remove it. We are very happy with the new faucet and the work Kerlin and Cameron performed. We look forward to calling Dial One Johnson Plumbing in the future. Thank you for your great service on the telephone calls as well.
