Frequently Asked Questions About AC Replacement
How much does a new AC cost?
The cost of your new AC will be affected by a few things, such as the type of system you need and the size of your home. We offer complimentary estimates for our affordable AC replacement and installation services, so don’t hesitate to contact us and learn more for free!
How long does an AC unit last?
An air conditioning (AC) unit typically lasts between 10 to 15 years. However, its lifespan can be extended with regular maintenance from our AC experts. Factors such as the unit’s model, usage patterns, and how well it has been maintained can affect its overall longevity. If you’re not sure of your AC’s age, or you’re not sure if it’s operating as efficiently as it used to, give AJM Mechanical a call – we’ll be happy to take a look.
How long can a house go without heat?
Some AC installations can take days – but when you call AJM Mechanical, you can expect a much faster process. In most cases, we can install new AC units in a day or less, sometimes even half a day. Of course, there are always exceptions, but we will go over our timeline with you before we get to work so you know exactly what to expect.
What AC unit should I get?
Choosing the right AC unit depends on a lot of things, including the size of your home, your cooling needs, energy efficiency ratings, and your budget. We usually advise our customers to pick a system with a high energy efficiency rating, as this can help you save on energy bills. Our HVAC contractors will be more than happy to help you shop around and find the right system for your family and your budget.
Need a New AC? Top Signs From Philadelphia's AC Replacement Experts
We’ve lived in the Philadelphia area for decades, so we know just how hot it can get – especially in those historic homes. It can be hard to know when you need a new AC, and that means it can break down when you least expect it. Our expert AC contractors at AJM Mechanical are here to share some signs that it’s time to replace your AC.
Your AC is Over 15 Years Old
The lifespan of an AC unit typically ranges from 10 – 20 years, but in our experience most systems give out around the age of 15. If your unit is more than 15 years old, it might be more cost-effective to replace it rather than paying for repairs all the time or putting more money into a unit that you’ll have to upgrade in a year or two anyway. Our team at AJM Mechanical will evaluate your system and help you make the most cost-effective choice.
Frequent Repairs
If you find yourself calling us for repairs more often than you used to, it’s a clear sign that your AC unit is on its way out. Frequent breakdowns are not only inconvenient for your family – they’re also a sign that your system is struggling to keep up with your cooling needs. This means your AC could be wasting valuable energy and making your energy bills higher. Let us help you save money by having us take a look at your AC.
Increasing Energy Bills
An unexpected rise in your energy bills can indicate that your AC unit is losing efficiency. As systems age, they have to work harder to cool your Philadelphia home, leading to increased energy consumption and higher bills. When you add up the cost of frequent repairs and higher energy bills, it can actually be more cost effective to replace.
Inconsistent Temperatures
If some rooms in your house are too cold while others remain warm, it could signal that your AC unit is no longer able to distribute air evenly throughout your home. This inconsistency often points to a failing system that needs an AC replacement – although we can try to repair it first. However, we do offer free estimates for installations, so you can get a personalized, professional quote at absolutely no cost to you.
Strange Noises or Smells
Unusual sounds, such as grinding, squealing, or rattling, or odd smells coming from your AC unit can indicate serious problems. These could range from electrical issues to mold growth within the unit, both of which are signs that an AC replacement might be the best option for your Philadelphia area home.
Your AC Uses R22 Freon
The production of R22 Freon, a refrigerant, has been phased out due to its harmful environmental effects. If your AC unit still uses R22, you’ll have to upgrade your unit to a system that can use a different refrigerant. Not sure what refrigerant your AC uses? Have one of our expert HVAC contractors at AJM Mechanical take a look. We’ll help you decide if it’s a better choice to upgrade your AC to a newer, eco-friendly model.
