HVAC means Heating, Ventilation, and Air Conditioning. HVAC systems refer to air conditioners, furnaces, and any unit that cools indoor spaces during the summer and warm them in the winter.

In general, an HVAC system takes in air, heats or cools that air, and blows it into a room or any indoor space. While many homes have separate air conditioning and heating units, others have a heat pump that cools and heats the house.

Not only do HVAC systems maintain desired temperatures, but they also improve indoor air quality and regulate humidity levels. But most importantly, these units provide comfort all year round.
The SEER (seasonal energy efficiency ratio) is a measure of the efficiency of your heating and cooling system.The higher the SEER rating, the more efficiently a unit operates. The SEER rating of any given unit can range anywhere from 13 to 21.

“CJ was very helpful and polite. He showed up an hour earlier than estimated and gave us a detailed review of our system’s functions and maintenance needs.”

Dan Hartnett

“My wife and I are satisfied with the work form One hour heating. Eric and Paul were fantastic. Very professional.”

Charles Tate

“We were without heat and temperatures in the house were falling. One hour quickly scheduled Ramone to diagnose the problem. He located, picked up the part and had it installed quickly. The entire process, from time of notification to completion of the job was less than 5 hours. Nicely done!”

Rick Yates

“I am very satisfied! Mr. Ramon did an outstanding job. He is very professional, polite, and focused. I liked that he explained what was wrong and what he was going to do. The heater works now! Thanks!”

Alesel

“My 6 yr old heater made a high pitched noise mid Sunday morning and stopped working. That was scary. I called One Hour Heating and spoke with Robert at 10:00 and had no response as of 12:15pm. Placed a second call and spoke with Victoria explaining my issue. Josh S. and Jimmy came to assess the problem. I required a new motor and the concern was having that motor in stock. My thermostat read 65 degrees and my anxiety spiked wondering if a motor was available. I said a prayer and gratefully Josh called stating he and Jimmy were returning with a motor. What a relief! I want to compliment Victoria for contacting the Technicians. I want to compliment Josh and Jimmy for their professional skill replacing the motor and their kindness as people demonstrating a supportive attitude to an anxious customer. One Hour is fortunate having Phone Staff that contact Technicians in a timely way and skilled Technicians that assess and resolve heating issues. Thank you so much!”
