Questions You Should Ask When Replacing your HVAC System

If you are considering replacing your HVAC system, you will no doubt have questions. Knowing the right questions to ask so that you can make an informed decision. Here are some questions to ask before you buy your new system. By asking the right ones from the outset, you will be able to find the right HVAC system to meet your needs.

What to Ask When Replacing your HVAC System

Q. Should I be looking at getting all of my HVAC equipment replaced at the same time?

A. Yes, all the parts of your HVAC system should be replaced at the same time to ensure that they work together properly. Replacing only part of your system may seem like the more economical way to go, but it could lead to service problems later on.

If the system is mismatched, it may not give you the level of energy efficiency or performance you are looking for. If you are replacing an older part of the system (piping, ductwork, furnace, or the outdoor unit of a heat pump) you’ll want to match the new part as closely as possible to the existing system.

When installing a new, high efficiency heat pump or air conditioner, the old ductwork could affect performance. It could have leaks, be inadequate for the new system, or not be the right size. Have the contractor perform a thorough inspection. All ductwork must be properly sealed and insulated, and the right size for your home.

Q. What size system should I buy?

If the system is too small, it will not heat or cool your home efficiently. Choosing a system that is too large will cost more and will not give you accurate temperature and humidity control.

Ask your contractor to prepare a detailed load calculation for you. It will determine the capacity of the equipment you will need and the correct distribution of air to each room in your home.

Q. What type of system is best?

When you are looking for an HVAC system, you have several choices available. When looking for a cooling system, you’ll notice that their efficiency is rated as a SEER (Seasonal Energy Efficiency Ratio) number. Highe numbers indicate that a unit is more energy efficient. Cooling systems must have a minimum SEER rating of at least 13.

What is the Difference Between an Energy Savings Plan (ESP) Maintenance Agreement and a Warranty?

As a homeowner, you’ll want to be proactive about taking steps to protect your heating and cooling equipment before any problems occur. Before you can make a decision about whether you should choose between an Energy Savings Plan (ESP) Maintenance Agreement and a warranty, you’ll want to make sure you understand the difference between these two items.

Difference Between an Energy Savings Plan (ESP) Maintenance Agreement and a Warranty


When you buy an ESP from Air Depot, you get a discount on parts and labor for any needed repairs on your heating and air conditioning equipment. A warranty usually has a specific list of repairs it will cover and you may have to pay a deductible for covered services.

Air Depot gives its ESP customers preferred day service when they call before noon for repair service on their heating or cooling equipment. Home warranty companies usually don’t offer this service, and customers may end up waiting several days for a technician to come to their home.

Buying an ESP means you will keep up with your scheduled maintenance on your heating and cooling equipment in your home. Air Depot’s ESP includes three inspections per year (with a written report):

  • The Cooling Maintenance Tune-up (May)
  • The Heating Maintenance Check (October)
  • The Annual Major Maintenance (February)

These checks are essential to keep your system running at peak efficiency and will extend its service life. If you don’t keep up with your regular maintenance and have the records to prove it, a warranty may not cover the cost of repairs if a failure happens or your equipment breaks down. Having the ESP in place can help to support the warranty.

Signing an Energy Savings Plan Maintenance Agreement with Air Depot means you get a heating and air conditioning contractor you can trust who will respond every time your system needs servicing, repairs or maintenance. When you choose a warranty, you have no control over which company will be dispatched to come to your home to provide services.

Which Programmable Thermostat is Right for Me?

Buying a programmable thermostat makes good sense if you want to keep your energy costs down. If no one is home during the day, it doesn’t make a lot of sense to spend money running your air conditioner at the same temperature as in the evening when you and the rest of your family are at home. During colder months, the thermostat can regulate the heat in your home in the same manner. How do you decide which programmable thermostat is right for you? Here are some factors to consider:

Choosing a Programmable Thermostat

Programibility – Level of Control

How much control do you want to have over your heating and cooling system”

You can get a seven-day controllable system that will let you set different programs for different days. This is a good choice if your schedule tends to change on different days of the week. This type of thermostat usually has four temperature periods per day.

A 5+2 model uses an identical schedule on weekdays and another one on weekends.

If you choose a 5-1-1 model, you will have the same schedule on weekdays and separate ones for Saturdays and Sundays.

User Interface

Programmable thermostats are available in digital formats with buttons, and newer models feature touch-screen technology. As the technology becomes more advanced, they tend to get more complicated in operation and functionality. You may find a touch screen thermostat to be more convenient than pressing several buttons to enter your programming instructions, but you will need to choose a model that you will feel comfortable operating.


Each thermostat will have features that are specific to that model. You can find ones that offer remote-control operation, which is handy if you want to change your program without being close to the unit. Humidity control is another feature that you can get with a programmable thermostat. Too much humidity in your home can lead to issues with mould and mildew. You can even protect your setting with a password if you wish.

If you have questions about programmable thermostats or want to confirm that the one you are considering is compatible with your air conditioning system, call Air Depot at


Does it Make Sense to Replace your Air Conditioner in late Summer?


If you have been noticing that your air conditioner has not been working as efficiently as it should be, you may be wondering whether it makes sense to replace it in late summer or if you should hang in until next spring. It can be tempting to want to hang onto an older model unit so that you can get every ounce of usage out of it before you get a replacement, but this is probably not the best choice. In a situation where you have real concerns that your system needs to be replaced, now is not too late to replace your air conditioner.

Why You Should Replace Your Air Conditioner in Late Summer

  1. Your older model air conditioner can break down at any time.
  2. There is still plenty of hot weather ahead and unless you are prepared to take the chance of being suddenly without air conditioning, you may want to choose to have the unit replaced at a time that is convenient for you.
  3. A newer unit is less likely to need extensive (and expensive) repairs.
  4. Rather than spending money on several repairs for an older air conditioner, you will likely be better off investing in a new system that will probably cost less in the long run.
  5. Newer air conditioner systems are more energy efficient.
  6. An older air conditioner will likely have worn-down parts that will need to work harder to keep your home cool. You may even notice that your home has some spots that are warmer or cooler than others. Upgrading to a more energy-efficient model will help you save money on your energy bill.
  7. A new air conditioner system will probably cost more next spring.

The longer you wait to make a decision to upgrade your air conditioner system, the more it will likely cost you to buy it. If you need an air conditioner, the best time to buy one is now!

Contact Air Depot at 281-477-3700 to discuss your new air conditioner needs today. We can help you find the right size and type for your home so that you can keep your cool for the rest of the summer.



Tips for Dealing with High Humidity in your Home

In the summer, warm and sunny weather is welcomed but very few people can honestly say they like humidity. This type of climate makes it challenging to be outside for and makes us feel drained of energy after just a short time. Potential problems from high humidity in your home start once it reaches the 60 level percent range or higher. At that point, you may start noticing the following effects:

  • Indoor air feels “stale”
  • Relative temperature is higher than indicated (humid air at 80 degrees feels hotter than dry air at the same temperature)
  • Increase in “bad hair days”

These are frustrating problems, but there are more serious issues that can affect your home from high humidity. If the problem is not checked, it creates the perfect breeding ground for mold growth.

Potential Health Issues Linked to Mold Growth

Household mold needs a warm, damp environment in which to grow. It can trigger a number of health issues, including:

  • Allergies
  • Asthma attacks
  • Irritation of eyes, nose, and throat
  • Respiratory problems

How to Deal with High Humidity in your Home

To keep household mold and mildew out your house, you’ll want to make sure that the humidity levels are kept in the 45-55 percent range. There are a couple of ways you can do this:

  • Make sure that your home is properly ventilated. While it would be unwise to keep the windows open – this will only let in moist, humid air from the outside – you can make sure that you use the exhaust fans located in your kitchen and bathroom. These are the areas of your home which are most likely to have the highest levels of humidity.
  • Keep your air conditioner well maintained. As the air flows through your home’s vents, it passes over the evaporator coil and deposits moisture onto it, which is blown off and then moves through a condensate drain. If your air conditioner is not working properly, it will not dehumidify you home properly, and you could end up with a frozen AC coil. If you see an ice buildup on your air conditioner, you’ll need to arrange for a service call from an air conditioner technician.

At Air Depot, we want everyone to have a cool, comfortable home this summer. If you are having issues with high humidity in your home or need air conditioner repair, contact us at 281-477-3700 today!
