Forget about spring: summer is right around the corner. With rising temperatures and the high cost of living, the last thing you want is for your air conditioning system to break down in the middle of the season. You also want to make sure it’s working efficiently so you and your family stay cool while your energy bills stay low.
Here are the top tips from the professionals on how to do just that:
1. When should I upgrade my AC unit?
When it shows its age. Many AC systems last 15 years or more, but they begin to lose efficiency as they age, especially without proper maintenance. A few telltale signs that it’s time for a new AC unit include:
- Unusual sounds or smells when it’s turned on
- The need for constant repairs
- Uneven cooling across the rooms of your home
- A malfunctioning thermostat
- High energy bills
If you do have to upgrade your AC unit, choose a high-efficiency model. Efficiency is shown as a SEER2 rating (a measure of how much cooling you get for the electricity used); the higher the number, the less it costs to run. Estimates for AC replacement are free, with a clear written quote.
2. How often should I clean or change my AC filter?
Every 1–3 months, and more often in a dusty summer. Your air conditioning system is constantly pulling in dirt, dust and debris as it circulates air. When the filter gets dirty and clogged, airflow drops and the system loses efficiency.
To make sure your AC unit is ready for summer, clean or change the filter consistently.
3. How much space does my outdoor AC unit need?
Keep about 2 feet clear all around it. Air conditioning systems depend on good air circulation to perform properly, so keep the area around your outdoor unit free of debris and any plants growing around it.
4. How can I reduce heat gain in my home?
Heat gain is the heat that enters your home from the sun, appliances and electronics. More heat gain means more energy use, because your air conditioning system has to work harder to bring indoor temperatures down.
To reduce heat gain, you’ll want to:
- Seal any gaps, cracks and holes around doors, windows and ductwork
- Insulate your attic well to keep cool air in
- Consider energy-efficient windows (or window tint)
- Add awnings, curtains or blinds to block the sun’s rays
- Plant trees and shrubs around your home for extra shade
Reducing heat gain keeps your air conditioning system from going into overdrive and possibly wearing out at the most inconvenient time.
5. Do I need a professional AC tune-up every year?
Yes, once a year before summer is the best habit. Keeping up with AC maintenance is key to the health and life of your system. While you can do the tips above on your own, it’s best to leave the air conditioning and heating maintenance to the professionals.
AC technicians are trained to work with all kinds of units. They know how to keep your air conditioning system clean and in good working order from the inside out, so it lasts for years to come. An AC tune-up is $135.
| Tip | Who does it | How often |
|---|---|---|
| Clean or change the filter | You | Every 1–3 months |
| Clear 2 feet around the outdoor unit | You | Start of summer, then as needed |
| Cut heat gain (shades, sealing, insulation) | You | Once, then keep up |
| Professional AC tune-up | A technician | Once a year, before summer |
| Check whether an old unit is due for replacement | A technician, during a visit | When repairs or bills keep climbing |
Key takeaway: Keep the filter clean and the outdoor unit clear yourself, and book a $135 AC tune-up before the hot weather. Comfort Club members get their maintenance visits included.

Summer AC questions
How much is an AC tune-up?
An AC maintenance visit is $135. With the Comfort Club, the Single System plan ($9.95/month or $115/year) includes 1 visit a year for one AC, and the Full plan ($18.95/month or $225/year) includes 2 visits a year for heating and cooling.
When is the best time to book AC maintenance?
In spring, before the first hot spell. That gives time to fix anything the technician finds before you need the AC every day.
How do I know if my AC needs replacing instead of repair?
Age, frequent repairs, uneven cooling and rising bills are the usual signs. A technician can look at your system and give you a free estimate on a new one if it makes sense.

We’re open Monday through Saturday, 8 AM to 5 PM, and closed Sunday.
