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.

“It was such a please to work with ‘One hour heating & A/C’. Called late in the evening with a emergency of co2 leak, got a pleasant call back from the owner himself on next steps and how to move forward he insisted on coming out to make sure my family was safe. I declined because the BCFD was already at my house and gave us at all clear, my service tech showed up on time and was so helpful yet full of knowledge. He serviced our unit and gave us peace of mind by walk through the whole house making sure the co2 was gone! Just amazing! Definitely would recommend.”

Lauren Redd

“From the moment I spoke with Jonathan this experience was exceptional. He explained some additional products and services that I could use and also order the parts the same day. When the technician (Ed) arrived he was pleasantly and professional. I had to make a run to go 5 minutes away to take my son to school and when I got back 10 minutes later he was done. I would recommend this company if you are looking for quality professional services. And no this is not a paid review. This is coming from a truly satisfied customer. Thank you One Hour Heating my family and myself really appreciates you!”

Octavia Battle

“Jon, the owner was very responsive. Their technicians were clean, professional, and not pushy at all. They took their time to explain the issues I was having, what likely caused them, and how the work they proposed would solve and prevent those issues in the future. They also made sure to show me what was happening instead of just telling me. I highly recommend them if you run into any HVAC needs!”

Daniel Schmerling

“I recently had an excellent experience with this company, notably due to Alex’s responsive, professional, and friendly service. From the moment I reached out, the team was quick to respond and schedule a visit. Alex stood out for his extensive knowledge and educational approach. He not only fixed our heating issue swiftly but also took the time to explain the process, ensuring we understood the work done. This level of customer care and expertise is rare and appreciated. I highly recommend their services for anyone facing heating problems. If you have the opportunity, specifically request Alex – his proficiency and approachable manner make a significant difference.”

Alexandré Wing

“Jonathan, the Owner, handled my anxious call to request service to my unit where heat and thermostat was not working. He patiently talked me through what the issue may be & provided much knowledge on my A/C & Heating inside & outside unit. Even though the weather prevented him from servicing the unit I feel he calmed my anxiety with great customer service and I trusted his diagnose that the fix would not be major. I will recommend him to others & look forward to working with him in the future. Thanks Jonathan for your time.”
