Degree-day

« Back to Glossary Index

A degree-day is a measurement used in HVAC and energy analysis to estimate the demand for heating or cooling a building. It is calculated based on the difference between a base temperature—commonly 65 degrees Fahrenheit—and the average outdoor temperature for a day. For heating, degree-days are calculated when the outdoor temperature is below 65°F, and for cooling, they are calculated when the temperature is above 65°F. This metric helps predict energy usage and system requirements to maintain comfort indoors.

Good service.

Audray Jones

First of all they are very courteous people. Secondly they gave me an appointment asap and was there right on time in which I was able to keep track of the arrival by text messages. They diagnosed the problem and it was resolved in less than 30mins. I am truly grateful for Paradise Heating and Air. Thank you for your service. Side note: they chose the best name for the company. I was in Paradise after the repair lol

Charles Reynolds

Jonathon, as always, provided great service! He is very efficient and honest. Thanks Jonathon, Charles

Jessica VanLandingham

He was on time and got the insulation job done quickly. I had contracted with another company who no-showed twice, so being able to call Paradise and get it done within a short time was great.

Love their service. They are very prompt and courteous. They get any issues resolved immediately and are amazing to work with!

SteelCityScreenPrint

Paradise answered my call late at night and made me an appointment for first thing in the morning and even showed up early. They crawled under my rental house through the dirt and mud to inform me that my landlord had me living in a dangerous environment. He was upfront and honest about everything and let me know the steps I needed to do to get my family out of this situation. No bandaid fixes from these guys, they do things in a professional manner and I couldn’t be more appreciative. Top notch customer service. Highly recommend!

Melanie Kettle

They scheduled me in a timely manner. The technician (Jonathan)was very professional, explained the system, and answered all my questions.

Brian Motley

My unit for upstairs had a major leak in the evaporation coils. Jonathan and Matthew came over and spent an hour here investigating and giving me my options. I decided to replace the whole unit and they were here on a Saturday replacing the unit. The knowledge that Jonathan possessed was second to none. The experience was excellent I will be using them again and I highly recommend them.

Ralph Ozley

Jon showed up as planned and committed to. A big plus was that he had the components on his truck to fix the broken part. Had my heat running after a 1 hour service call. Yes, I would recommend Paradise Heating and Air ...5 Star rec.

john DiOrio

Jonathan and the Paradise team are the best. In my 50 yrs of home ownership, I haven't had anyone I've trusted more. My wife and I downsized recently, and Jonathan helped us upgrade old to new heating & air units, including thermostats and attic insulation. Paradise Heating & Air is a great company... glad we found them years ago.

Mark Hamblen

Did a very thorough job of servicing my system. Will use again.

Buckley Rose

Awesome customer service. Exceeded my expectations compared to past experiences with different companies

Sandy Hicks

Being a first time customer I was extremely impressed with how punctual and professional the technicians are. I highly recommend Paradise Heating and Air

Danna Jones

Great service - always on time and very professional.

Dave Meyer

I was extremely impressed with Paradise Air and am very glad I found them. I have a very old HVAC system they needed some ducts and a condensate pump replaced. They were extremely thorough and clearly explained everything they planned on doing. The price was excellent given how much work they had to do in the crawlspace and the extra time they spent with me advising me on how to get as much out of my old system as I could. They weren’t there to try to sell me a new system. They were there to repair what I asked them to at a reasonable price and help me extend the life of my current system. I won’t even think of calling anyone else from now on.

D. C. Smith

Replaced a furnace vent pipe and roof cap, Jonathan and Matt were competent technicians and explained everything to me clearly and the quote and the final price were the same. comparing quotes, they were very competitive and provided a high degree of professionalism on the job. Thank you very much.!

Edna Cumbee-Montieth

We had Jonathan out to service our unit today. The service was quick and efficient! Jonathan’s experience speaks for itself! We highly recommend Paradise Heating and Air for all your HVAC needs. Trevor and Edna Cumbee-Montieth Hoover, AL

Ruthie McNeil

I was fortunately able to get an appointment for the next day. Jonathan & Austin were prompt and kept me advised of their arrival. They quickly found the problem with my "heat" and were able to fix it without problems. They were very friendly and professional, and I felt that their pricing was fair and reasonable. Thanks again, Guys! UPDATE: I once again had a very good visit from Paradise Heating & Air - they are very prompt and reliable and do an efficient job - thanks once again! I definitely recommend these nice guys!!!

Michael Robinson

Jonathon and Christian did an excellent job! We would recommend them highly!

Mary Cavett

Paradise has become our go-to HVAC company. We have used them for several smaller repairs and they always provides a reasonable price and didn’t try to upsell replacing our 30 year old unit before we were ready. Then, when we were finally ready to replace our unit we got quotes from Paradise and several other companies. Paradise was by far the best value not only in terms of price but also unit brand and warranty. We even ran all of the quotes through AI and his came in 1st in terms of value, price and ROI! Great company overall - can always trust them to provide great, high quality work and reasonable prices.

Eddie Dawson

Fast on time & courteous

Rory Chrane

Update: May 2026 Paradise came and serviced my business and home this week per the service agreement I asked them to sign me up for. Excellent trustworthy people and processes yields a top level result. You can trust them too. Call them and see what I mean. From the first phone call, I was impressed, I spoke to Jennifer and on a follow up call, I spoke to Gracie. Both are related to the owner Jonathan who came out today and gave me a breakdown and an idea of what is needed and proposed how to go about doing a mini split, which I’m excited to get done, so much so that I wanted to give a review, even before the work begins which I’m sure will be excellent. He recommended a good brand Mitsubishi and explained why he chooses them, giving a very detailed explanation. Jonathan was very personable and efficient and I look forward to the job being completed and future business with this company.

Dana Gaudet

I recently had this company come out to my home because my unit wasn’t working, they had someone out the same day. Jonathan was extremely professional and knowledgeable, definitely recommend this company!!

VWC

Amazing service and very helpful as well as willing to inform me of what was going on.

Melanie Authement

Honest and kind. Gave incredible price for work completed. Called and was able to come earlier than expected! Cannot recommend enough

Blake

We recently bought a home and right away one of the AC units failed. Of course it was after hours (do AC units ever fail not after hours?). I called Paradise Heating and Air and they dispatched quickly, diagnosed the problem, and had us cool and running again before the kids were even in bed. Jonathan figured out the issue fast, and the quality of work and the cleanup afterward were truly noticeable. They've become our go-to HVAC company, always a notch above on service and workmanship. If you need emergency AC repair or any HVAC work in Vestavia Hills or anywhere in the Birmingham area, don't hesitate to reach out to this team. Love working with them!

Christopher Lee

Jonathan was very knowledgeable and friendly. Appreciated his candor and non-salesy guidance. We will be using them again.

samuel wilson

Tech was on time, very professional, courteous, knowledgeable addressed my concerns about the system. Will definitely be recommending Paradise Heating and Air.

Abby Beckloff

I called at the end of the workday on Friday when we arrived back home from a trip and the temp in our house was 114! We had, fast, fair service and were cooling off within the hour I had called. Excellent experience!

Adam Myers

One of our AC units decided to give up, or so we thought. We had several companies come out and give us a quote to replace our unit, all exceeding $13k. Paradise came out, and instead of just giving a price to replace it, they asked if they could tinker with the equipment. They had it fixed within 10 minutes!!! Paradise gave us a quote so we have an idea of the cost for when this ancient unit ACTUALLY dies, and it was $3k-$8k cheaper than our other quotes!!! They could have easily just given us a price for a new unit like everyone else. I appreciate that Paradise put forth the effort to figure out the problem, and saved us THOUSANDS!!!

Kofi Creme

My unit was not working and they were working with my relatives. I asked if they would take a look at mine and they did with no problem. They told me what the problem was an within 2 days they had my unit up and running!

Katherine Marshall

Extremely nice, on time, helpful and explanatory. Very professional. Thank you

Linda Thompson

Jonathan and his helper were awesome. Keeping us informed as to what they were doing as they replaced our heating and air units. They were pleasant to have around and did a great job. They not only left the areas clean they hauled off all the old equipment. We would highly recommended them to everyone.
