Default Guaranteed Temperature Reduction indoor during summer.

I am not a resident yet, but I was wondering if A/C contractors in TV will guarantee a 20 temperature reduction during a hot summer day? I am presently living on Long Island, NY and that clause was written into my A/C contract.
Second question: What indoor temperature do you prefer in the summer?
Thank you! MarvinH

Should go to the source and ask contractors.

The word of posters on a social media site is of zero value.

Dont know if there is any guarantee. We keep the temp at 72 during the summer and, even when the outside temp is over 90, it maintains the 72 degrees

I have never heard of an AC contractor ever making that type of guarantee anywhere. How would you enforce the guarantee?

We set an indoor temp of 76.

I find that the humidity setting is also important. We set the humidistat at 50%.
Many thermostats also include the humidity setting.

I wouldn't worry if I were you. The whole house AC units are very efficient & mine kept my house wherever I set it regardless of the outside temperature.

I don’t think the developer would include that in your contract.
Most air conditioning systems can only handle a 20-degree difference between the outside and inside air temperatures

When the house is designed there is a document supplied with the plans that covers the heat and AC load so that the HVAC system is sized correctly, I expect this would be the governing document. On a side note, we have been here over 10 years in a concrete block house, and have never had a problem with heating or cooling.

Check your contract to see if the guarantee is for a 20 degree F difference between the indoor set temperature and the leaving air temperature from the furnace. My heat pump generally achieves 20 degrees F when I run either air conditioning or heating.

I keep my thermostat at 77 degrees in the summer, 68 in the winter, and have the windows open in spring and fall.

The minimum AC sizing standard is the ability to cool a home to 78 to the 95th percentile of days that require cooling.

Now there are plenty of years where the 95th percentile does not apply. Also AC units are not precise in size. For example, it could be that your home requires a 3.15 ton unit. The closest size that will work is 3.5 tons, an increase of over 11% in cooling capacity.

I'm guessing you own an older home?

Newly constructed homes are required to meet the Florida Building Code, which is the International Building Code (IBC 2021), with some modifications. New construction is also required to meet the Florida Energy Code, which again, is the International Energy Conservation Code (IECC 2021).

What that means in simple English is, prior to getting a building permit (including an HVAC replacement), the applicant has to produce an energy audit/analysis to verify proper HVAC sizing for a given structure. The Code dictates the size (capacity) of the HVAC system.

HVAC systems installed in the USA, generally have to meet Energy Conservation Codes, which essentially dictates the cooling/heating capacity and rate.

As a practical matter, any HVAC system installed in a home in the USA, will surely lower your temperature more than 20 degrees. The only variable, is how long it takes (& that's regulated by the energy code). As a rule of thumb, an HVAC system can move temperature up or down, about 3 degrees per hour.

A residential house temperature is personal preference. In a work environment, OSHA requires a temperature of 68 -76. We cool our offices/retail properties to 74 degrees in the summer (not located in Florida). My house is set at 76.

Here's a couple of links that explain how it works and why you don't want an HVAC unit that's too big for your home, nor too small. Weird, huh? You should get a properly sized unit.

Sorry, I didn't read all of your post, when I posted my answer.

Mr VIllageTinker is correct. Florida law requires that you're supplied with the Energy Audit/Analysis when you buy a new home.

Please provide the link to that reference?

I set my 77 most or time. If I go too much lower my lung’s congest makes harder to breath.
