Signs Your System Needs Attention

Recognizing heating problems early can prevent costly breakdowns and keep your home comfortable throughout the winter. Watch for these warning signs that indicate your system needs professional attention:

Uneven heating: Cold spots or rooms that fail to warm up properly may indicate issues with the ductwork or system inefficiency.
Rising energy bills: Sudden increases in heating costs without explanation suggest your system is working harder than it should.
Frequent cycling: If your heater turns on and off repeatedly, it may be experiencing issues with its thermostat or mechanical failure.
Yellow pilot light: A pilot light that's yellow instead of blue can indicate dangerous carbon monoxide production requiring immediate attention.

“I had a new furnace and ac installed. Jonny and Tyler B did an amazing job from start to finish. They are both very good at what they do. They had to install new lineset for my new system and it came out looking awesome (even the city inspector commented on how good it looks). The sheet metal work on the new furnace that Jonny fabricated looks amazing as well. I will recommend One Hour Heating and Air to anyone and I can't thank Jonny and Tyler B for the awesome job they did!!”

“We just completed our fall maintenance appt. for our furnace with One Hour Heating and Air Conditioning’s technician, Joseph. He was on time, courteous, professional, and explained a few small adjustments that needed to be made with the furnace. He was knowledgeable and we were very pleased with his service. Thank you One Hour for your great service and technician!”

“Very good service from our technician Anson. He texted us with his arrival time about an hour before. He completed the furnace maintenance efficiently and thoroughly. He also took time to explain what he did and things that we should be aware of as well as things to do ourselves. I'm very pleased with the service and would recommend them.”

“Joseph C was our technician and he did an excellent, efficient and expedient job! He explained first to us what he would be doing and then when we had questions while he was working he answered those so that when he was finished we knew he completed everything satisfactorily. We even teased him about his pink booties. I realized he was representing Breast Cancer Aware month and was happy that the company supports that! Great job, Joseph and one Hour! Thanks so much!”

“Cameron had been at our home when we had problems with our mini split system, which he helped solve. So he remembers us, our system, and knows the importance of regular maintenance. He is a gem! Very well versed in our system, technically very up to date, and an extremely nice guy!!!”
