What does the One Hour mean in your company name?

The 'One Hour' in our company name indicates our guarantee to be at your home in the predetermined window quoted when you set your appointment. If we do not show up within that window, your service call fee is waived. 1. Express Appointment: This is an appointment that is scheduled during a specified one-hour time slot. You are promised that a technician will arrive at your home within this one-hour time window. You will also receive a call when the technician is en route to your home. 2. Reserved Appointment: This is an appointment that is scheduled during a specified, two-hour time slot. You are promised that a technician will arrive at your home within this two-hour time window. You will also receive a call when the technician is en route to your home. 3. Standard Appointment: This is an appointment that is scheduled during a specified four-hour time slot. You are promised that a technician will arrive at your home within this four-hour time window. You will also receive a call when the technician is en route to your home. 4. Stand-By Appointment: This appointment is for overflow situations. This appointment will not have a specified time. You will receive a call when the technician is en route to your home. 5. Emergency Appointment: This appointment is for an unspecified time after normal business hours Monday – Saturday and all day on Sundays/Holidays. Calls are dispatched in the same order they are received. You will also receive a call when the technician is en route to your home.

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 SEER Rating?

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.

“I had a great experience working with Bruce for my HVAC service. From the moment he arrived, he was professional, courteous, and clearly knowledgeable about his work. What really stood out was how well he explained the issue with my system. He broke everything down in a way that was easy to understand, without any technical jargon, which I really appreciated. I’d absolutely recommend Bruce to anyone in need of honest, reliable HVAC service.”

“Always professional and timely service. I have had the pleasure of using multiple services of One Hour. They perform twice a year HVAC maintenance and I have utilized their electrical and plumbing services. Most recent service from Max was prompt and though. He explained the next steps for managing my systems. Jeremy, from their electrical department, spent a day installing can lighting, under cabinet lighting and fixtures. I was completely satisfied with all the work that was done in my home. Office support staff are very kind and helpful in setting up my account for payments and appointments.”

“Bruce was very professional and personable. He was thorough in checking for the problem. He showed and explained the malfunctioning part and shared parts prices with me.”

“Signed up for the Comfort Club not thinking we would need it. HVAC technician Leif stopped by and honestly went through everything (checked the AC unit, the system in the attic, washed the unit and even checked the ducts). Once done he went over what he found and was very honest in his recommendations (necessities over basic one off items). Well worth the investment and am still shocked at the level of detail he went though along with the images he took! Very much impressed!”
