Do you service emergencies after-hours?

Yes, we offer emergency services 24-hours a day, year-round.

How much will my service cost?

The size and complexity of your HVAC issue will determine the cost. Because our trained, licensed HVAC technicians must diagnose the issue before we are able to quote you an accurate cost, we require an appointment to be set to complete a diagnostic on your system. Once the diagnostic is complete, your One Hour(R) technician will walk you through all costs using our Straightforward Pricing(R) Guide so there are never any surprise fees.

How often should I service my HVAC system?

It's ideal to service your cooling system each spring and your heating system each fall to ensure you find small issues before they become big problems.

How often do I need to change my HVAC filter?

Your filter should be changed every one to three months, depending on conditions in your home and your region's climate.

Do you offer purchase financing?

We work built relationships with several lenders to ensure our customers are able to restore comfort in their homes. Ask your technician about your financing options.

What are the advantages of a smart thermostat?

Smart thermostats learn a household's patterns and adjust heating and cooling according to when a home is occupied, give homeowners the ability to control the thermostat remotely, and enable homeowners to reduce their energy use, saving you money.

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.

What is a SEER2 Rating?

The SEER2 (seasonal energy efficiency ratio) is a measure of the efficiency of your heating and cooling system.The higher the SEER2 rating, the more efficiently a unit operates. The SEER2 rating of any given unit can range anywhere from 13 to 21.

“A few weeks back we had Seigert One Hour replace our upstairs AC unit and duct work in our attic and install a mini split system in our garage. They were excellent! The crew arrived on time and were extremely professional and courteous. They also completed each job in one day and did a great job of cleaning up any mess they made. I would highly recommend them for any AC job you are considering, and we are loving our new units. Thank you!”

“I recently had an AC unit installed by Siegert, and I couldn’t be more impressed with their service! The team was incredibly fast, completing the installation efficiently without cutting corners. Their professionalism was evident from start to finish—they arrived on time, worked diligently, and left the area spotless. What stood out most was their clear communication; they explained every step of the process in a way that was easy to understand and patiently answered all my questions, ensuring I felt confident in the system. I highly recommend Siegert one hour heating and air conditioning for anyone needing AC installation—top-notch service all around!”

“Shout out to Eden Garcia at Siegert One Hour Heating and Air! When my compressor unit broke down (fan blades literally broke off) suddenly in the middle of the day, I called One Hour to see if they could get anyone out that afternoon. Eden was able to make it over just past 4. He was confident it should just need that fan piece replaced and it should be running fine again, that it didn’t sustain any further damage. He was able to jump into action, get the part quickly before the parts shop closed for the day. The repair worked as he expected and my a/c was back running the same day! I appreciate his quick thinking and Siegert for having him on their team!”

“Eden from Siegert One Hour Heating & Air Conditioning was great at communicating clearly. He was great to work with. He was professional, empathetic to the state of our plumbing needs, and provided a follow up call to make sure he advised of all the work that had been completed. He went an extra mile to state that if I needed anything, he would be glad to follow up. Much appreciated. Thank you so much Eden! Regards- DH”

“The technician arrived on time, was very courteous and knowledgeable. Used shoe covers while in the house the entire time. Did a thorough review both inside and outside! Gave us information that would be useful to fix one of the problems he found. Highly recommend this company!!”
