What’s the best thermostat setting for summer in Glastonbury?

For optimal comfort and energy savings during summer in Glastonbury, set your thermostat to 78°F (25°C) when you're home. If you're away, raising it to 85°F can help reduce cooling costs. Using a programmable or smart thermostat can make these adjustments automatic and more efficient.

Do you provide emergency after-hours HVAC service in Glastonbury?

We are available 24/7 to take your call for emergencies. Our appointment hours are listed above.

How can I improve indoor air quality in Glastonbury?

To improve indoor air quality in Glastonbury, start by regularly changing your HVAC filters, scheduling routine maintenance, and using air purifiers. Consider duct cleaning if your home has excessive dust or allergy symptoms. Proper ventilation and keeping your home clean are key to healthier air.

How often should I service my HVAC system in Glastonbury?

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.

Do you offer HVAC financing in Glastonbury?

We work with several lenders to provide financing options for qualifying customers. Ask your technician about your financing options.

How often should I have my furnace serviced in Glastonbury?

It’s recommended to have your furnace professionally serviced once a year, ideally in the fall before the heating season begins in Glastonbury. Annual maintenance helps ensure safe operation, improves efficiency, and can extend the life of your system.

How often should I have my air ducts cleaned in Glastonbury?

It’s generally recommended to have your air ducts cleaned every 3 to 5 years in Glastonbury, or more often if you notice dust buildup, allergies, or musty odors. Homes with pets, recent renovations, or high pollen levels in Glastonbury may benefit from more frequent cleanings to maintain healthy indoor air quality.

How often should I schedule AC maintenance in Glastonbury?

You should schedule AC maintenance once a year, ideally in the spring before the cooling season starts. Regular tune-ups help your system run efficiently, prevent breakdowns, and extend the life of your unit, especially important in Glastonbury's summer climate.

What size HVAC system is right for my home in Glastonbury?

The right HVAC system size for your home in Glastonbury depends on factors like square footage, insulation, number of windows, and local climate. A professional load calculation ensures your system is properly sized for comfort and efficiency. Oversized or undersized units can lead to higher energy bills and uneven temperatures.

Very pleased with this company and our technician, Joshua. Scheduling was efficient and fast, they came out the same afternoon that I called. After I had another company come out that morning and tell us they could not fix my furnace dehumidifier, Joshua had it fixed in a short time after his arrival. Pricing was very fair. This is my new HVAC provider!

Andrew was excellent in his detailed review in quoting out a new heating/AC system for our home. He asked what I was looking for and we went room by room reviewing what was in each room. He confirmed that the current layout was very good and the system we had was the correct in its ratings. He prepared our quote as I had asked, no pressure with any additional ons or upsells as I was clear in what we were looking to do. He went over the quote with me line by line asking if I had any questions. Andrew was very polite and professional throughout the whole process. Can’t say enough good things about the dealings I have had with these two gentlemen along with the young lady I talked to on the phone. If you’re on the fence- call these guys.

"Great experience with One Hour Air! They showed up right on time, replaced my thermostat, and did a thorough AC maintenance check. Their pricing was very affordable and honest and their technician James was extremely knowledgeable. He explained everything he was doing and made me feel completely comfortable. He broke everything down clearly and never talked down to me or made me feel stupid. Highly recommend!!!

Glenn was very impressive. He was here for over 5 hours working very hard to find a solution. He also was very honest with me about the issues to our units and I appreciated that a lot. Highly recommend.

DeAndre Yarbrough, the service tech was knowledgeable, clear and concise in his explanations, honest about priorities (mega kudos on that front), pleasant and friendly in his demeanor. I, literally, have zero complaints. He was absolutely great. I felt very comfortable with his explanations and service on my system.
