Do you service emergencies after-hours?

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.

“(7/12/24) I was very pleased with the service that was provided to me today. My service provider, Mir, did a great job and was very knowledgeable. Keep up the great work, and I will definitely be a repeat customer. UPDATE!!! 7/24/24 There was a piece left off of my unit when the technicians came back to replace a part my unit needed after having the coils and blower cleaned. I was pretty upset with this situation, especially when the manager told me the piece I was talking about should have been removed at install. I knew this was not the case. Thankfully, they sent a tech back out here today to pit the part back in. Yasser, is who they sent out today. Thanks for moving on this quickly! I greatly appreciate it!”

“Hi it's Karen First of all I like to say how impressed I am with the wonderful service, the incredible work ethic and the hard work from the AC team that came to install my brand new unit today. They were punctual, very well mannered and very hard workers. I found the company through Google, the ease of appointment was simple and the next morning I had a text giving me all phone numbers for the repair I had scheduled. First of all I met Alberto within reaching the staircase he diagnosed my AC issue and I was very impressed how he knew it was 14 years old. It was a Rheem. He told me that the motor has to be replaced and possibly the compressor. He gave me 3 options, gave me time to decide, and advised I could talk to a salesperson that same day. So the office called me and scheduled salesperson for 3pm. This was yesterday. I had the pleasure of meeting the most delightful sales and extremely helpful/ accommodating associate Yurais. The office called and he came punctually at 3pm. He is extremely pleasant, he is a great communicator. I explained my budget and he did an analysis of my home and my AC needs and found me an outstanding unit. The next day, the team messaged me and called me before they arrived and worked on my unit non stop. They came exactly at the time I asked for. Very hard working, respectful to my property and stayed all day and until past 8 pm to ensure the unit was working perfectly. Yurais and Albert told me about the member program and I joined the service. It is twice a year and they service and maintain the AC. Yurais came by as well today on install day. Spent time at my home insuring everything went smooth and he answered my questions. Yurais even scheduled my plumbing as this company does Plumbing and electrical as well and while the crew worked Miguel fixed my toilet and drain. I give the company 5 stars but they deserve the whole galaxy of stars. I look forward to seeing my techs again for my service needs and also look forward to working with Yurais to see if I can get the UV light in my unit and get some duct cleaning. I am so happy God sent me this wonderful company and I am so happy I financed my unit. I really thought with my budget it be impossible but Yurais got me a great monthly fee through the finance company. The Financing is a very quick process and even the permits are included with AC purchase. I even spoke to a notary today. Unit has a wonderful warranty and I know I will enjoy this AC everyday. The company works 24x7 so they are there for your schedule. Thank you Team you are all amazing. I love my new unit. You made my day and we are very happy. My family and pets will be enjoying the cool AC. It was a pleasure doing business.”

“I recently had a routine air-conditioning maintenance appointment, and I couldn’t be more pleased with the service provided by Yasser. He was punctual, professional, and extremely knowledgeable. Yasser took the time to explain what he was doing and made sure everything was running efficiently before he left. He was respectful of my home, left the work area clean, and even shared a few helpful tips to keep the system in top shape. Great experience from start to finish—I highly recommend Yasser for any A/C maintenance needs!”

“Broken air conditioning is unwelcomed news in our area, however, the technician, Mr Mir, with One Hour Air came and determined that it was a faulty unit. We had to wait for the new unit to arrive, but Mier and his manager, Mr.Helio, sent us portable air conditioning for the few days that we waited for new unit. Excellent professional service and expertise. Highly recommend the company and technician.”
