The relentless Texas heat is here which means HVAC replacement season is in full swing. Investing in an HVAC system is a big decision, and you don’t want to pick the wrong one for your home – so how do you know which system is the right one?
First, get familiar with the following equipment and efficiency ratings:
The table below shows efficiency ratings for good, better and best heating and cooling equipment.
There are 3 types of ratings that you should be aware of :
Why it’s important to have the right sized system.
Now that you understand the types of equipment and their efficiency ratings you can look at what size equipment is right for your home.
One of the biggest mistakes people make when selecting an HVAC system on their own is they tend to get a larger system than what they need which can lead to multiple problems.
Humidity is a key factor when talking about cooling a home – which Houston has plenty of. A cooling system that is too big will cool down the temperature in your home quickly, but it will not run long enough to remove the amount of humidity necessary from the air. This will result in your air feeling cool but clammy, yuck. To get rid of the clamminess, you'll end up turning down the thermostat even more which makes the unit run longer and increases the energy bill. Other disastrous results can occur from not ridding your home properly of humidity like mold and mildew growth along with other moisture related damage.
A properly sized unit will run just long enough to remove the necessary amount of humidity from the air allowing you to sit comfortable in your home at a higher thermostat setting which ultimately saves you money on your energy bill.

How to calculate the right system for your home.
To understand which system is a perfect fit for your home whether installing from scratch or upgrading an existing unit you’ll need to calculate the load of your home.
The load of the home is partly dependent upon the home’s square footage. However, a true load calculation goes beyond that. An accurate load determination includes building construction; orientation to the sun; “R” value of the insulation; number, size, and placement of rooms; number, size, and placement of windows and doors; types of windows and doors (thermal efficiency); number and arrangement of floors; and the climate. 
Sounds like a lot to consider, right? It is! Which is why relying on a professional is usually best for fitting a new system to your home.

You probably don’t think about your trusty HVAC system often. It’s kind of like breathing, your lungs are always working to pull new air into your body but it’s not something you think about. Just like your HVAC system runs behind the scenes to keep you comfortable in your home. As long as you’re comfortable, it’s just not on your mind. But the minute dull, hot air wraps around you like a blanket while watching TV – you instantly think, “Uh oh, what’s wrong with the AC?”.
What to look for when your HVAC system starts to fail.
Luckily, you don’t have to wait until your HVAC system stops working on a 95-degree day when your friends and family are coming over in an hour to celebrate your Son’s Birthday (that’s always when it happens, right?)
Be on the lookout for signs that your HVAC system might be reaching the end of its life:
1. No cool air. Period.
If you keep turning down your thermostat lower and lower and no cool air comes out at all, it’s pretty much a dead giveaway something is wrong. It could be that you need a Freon refill or something more troublesome like a blown compressor.
2. Wacky thermostat.
One second your thermometer reads 72-degrees, the next it reads 80-degrees. If your thermostat is set to one temperature but you keep noticing a fluctuation throughout the day, it could mean your thermostat needs replacing or it could be signs of a larger problem to come.
3. Run Forest Run.
If your AC is running all day long and never stops it could mean a multitude of things – anything from a dirty air filter, to your unit being undersized, to your ducts being clogged, to your unit simply being old. Usually, it is a combination of any of these. Like a beloved dog, HVAC units have a life span of around 15 years. If your AC is running all day, it’s a good idea to have it checked to see what’s up.
4. This room’s hot – this room’s cold.
If you feel like Goldilocks going from room to room trying to find the temperature that is just right for you – your AC might be ready to call it quits. An AC that isn’t working efficiently might not be able to pump cool air to the parts of the home that are further away, resulting in rooms that are cold and rooms that are hot.
5. Something doesn’t smell right.
Did that pesky squirrel hit the dust in the attic or What. Is. That. Smell?! If you’re picking up something stinky it could mean your unit’s wiring has burned out or there could be a build up of mold and/or mildew in the duct work, AC unit or both. This growth can have negative health implications for your family so if something smells bad, it’s time to have a professional come inspect your HVAC system.
6. A decline in the quality of air.
Last summer the house felt crisp, brisk and comfortable all summer long, like taking in a breath of fresh mountain air. This summer, the air feels heavier, almost like taking a deep breath on an ozone warning day in downtown Houston. Somewhere along the way, you feel like the air quality in your home has declined. This could be due to your ducts needing a good cleaning or it could mean your compressor or capacitor is failing. Either way, it’s time to get your unit checked out.
7. That doesn’t sound right!
If you start hearing bangs, clanks, screeches, whistles, grinding or grating from your HVAC unit, something’s up – usually broken motor bearings, slipped belts, or the system just needs a good tune-up with lubrication.
8. Is that a damp spot?
Woah – that area is supposed to be dry! Maybe your refrigerant is leaking or your conduit that disposes of condensation is broken or blocked. Don’t let obvious signs of dampness go unchecked – it can lead to mildew and mold growth that will cause even more complications down the road.
9. Higher energy bill.
Ouch – that energy bill hurt to pay! If you notice your energy bills climbing at a rate that is not normal for the time of the year, it could be that your HVAC unit is not running as efficiently and needs to be inspected.
10. Multiple Breakdowns.
If your HVAC system is being maintained as it should twice a year by a professional – it shouldn’t be randomly breaking down as most common AC issues are caused by a lack of maintenance. If you notice multiple instances where you’ve had to get repairs on your unit, it’s probably a sign that your system will need replacing soon. Talking with your HVAC professional will help you determine if it’s better to replace your unit now or continue risking costly repairs in the future.
When it comes to replacing your unit – nothing goes in the same way it came out. There are always newer, more efficient units on the market and better options for your home. Our specialists at County Air will help fit a system to your home and budget’s needs so you can stay comfortable year round.
