There’s no reason to sweat and suffer through summer when you could be keeping cool with a new central air conditioning system. The first step is to have a Heritage HVAC specialist come out to your house and do a thorough analysis of your home’s cooling needs. This will help us recommend the best central AC system for the job.

It usually takes only one day to get a brand new central AC unit installed in your home by our 5-star technicians. We also do all of the necessary air duct work to minimize the amount of energy lost through the ducts when your new system is running.

Do You Need Central AC Repairs, a New System?

Homeowners can troubleshoot some common problems themselves, but most air conditioning issues require a professional HVAC technician who can also assess whether you need repairs or whether you’d be better served by a new, more energy-efficient central air conditioning system. Here are some common air conditioning problems and potential causes/solutions.

Problem: My Air Conditioner Isn’t Cooling Effectively
Potential Causes/Solutions: Possible causes include refrigerant that is low or leaking, thermostat issues, a clogged drain or a dirty filter. You can and should regularly change your filter (every 6-9 months for high-quality 4-inch-thick filters; as often as every 30 days for cheaper 1-inch filters). You can also check to make sure your condensate drain line is not clogged, and check your thermostat to make sure it is set properly and is reading the correct temperature. Issues involving refrigerant are best handled by an HVAC professional because EPA certification is required.

Problem: My Central AC Isn’t Working At All
Potential Causes/Solutions: First, make sure your thermostat is functioning; the problem could be as simple as a burned-out battery. Also, your outdoor compressor and fan controls could be worn out from turning on and off too frequently. If so, you’ll want to check (or have a professional check) your unit’s electrical connections.

Problem: My Air Conditioner Has Limited Air Flow
Potential Causes/Solutions: Your ducts could be clogged or constricted, or leaking air. Your filter could also be part of the problem, restricting airflow through your system, cutting its efficiency and reducing its ability to cool the air. For central air systems, our technicians check for and seal any duct system leakage as part of your periodic maintenance.

Problem: My Energy Bills Are Unusually High
Potential Causes/Solutions: A spike in operating costs most often signals inefficient operation. After a dirty filter, the most likely culprit may be a choked condenser coil. If so, it is probably time for a tune-up.

Frequently Asked Questions

Q: Should I turn off my air conditioning system while I’m at work?
A: No. Though that may sound like an efficient way to save energy, the opposite is true. Turning your system off during the day forces it to work harder to dehumidify and cool your indoor air when you get home, and to contend with heat that’s been building up in your walls and furniture all day. Instead, use a programmable thermostat to “set it and forget it” a maximum of 3 degrees warmer than your temperature setting when you are home.

Q: What is the expected life span of a central air conditioning system?
A: It varies, of course, but the average is 15-17 years. In some new construction projects where the emphasis is on keeping costs to a minimum, the less-expensive systems chosen may have a shorter lifespan, averaging 11-13 years.

Q: How important is proper sizing of a central AC system?
A: Proper sizing and installation are key elements in determining air conditioner efficiency. Too large a unit will not adequately remove humidity. Too small a unit will not be able to attain a comfortable temperature on the hottest days. Improper unit location, lack of insulation and improper duct installation all can greatly diminish efficiency.

Q: Do I ever need to have my refrigerant “topped off”?
A: No. HVAC systems do not consume the refrigerant as part of the cooling process. If the refrigerant is low, this indicates either that there is a leak or that it was set up improperly.

Q: How efficient are central air conditioners today?
A: Today’s most efficient air conditioners use 30% to 50% less energy to produce the same amount of cooling as air conditioners made in the mid 1970s, according to the U.S. Department of Energy. Even if your air conditioner is only 10 years old, you may save 20% to 40% of your cooling energy costs by replacing it with a newer, more efficient model.
