We Can Fix Your Broken A/C System and Provide Preventive Maintenance

AC and Ductless AC repair and service

A broken air conditioning system can be extremely frustrating, especially since they most often seem to break down when the weather is scorching hot. Whether your system is no longer cooling, is leaking, or you’re experiencing short cycles, our HVAC professionals can repair your central A/C unit and ensure that your home is kept comfortable during the hot summer months.

Your home should be a haven of cool from the discomfort of summer heat and humidity, and scheduling routine maintenance is necessary to achieve this. When it comes to routine air conditioning service, it’s important to remember that industry best practices call for annual maintenance. Many manufacturers also require it so your unit stays current under warranty. We specialize in air conditioning maintenance and tune-ups to help ensure that your system meet warranty requirements and keeps you cool all summer long.

When performing an air conditioning tune-up, our expert HVAC technicians:

  • Check to ensure the correct amount of refrigerant
  • Test for refrigerant leaks using a leak detector
  • Capture any refrigerant that must be evacuated from the system
  • Look for duct leakage in central air conditioning systems
  • Measure airflow through the evaporator coil
  • Inspect electric terminals, clean and tighten connections, and apply a non-conductive coating if needed
  • Oil motors and check belts for tightness and wear
  • Check the accuracy of the thermostat

Common Air Conditioning Problems

While most air conditioning services require an HVAC professional, homeowners can troubleshoot many common home A/C problems. We’ve provided some information below to help you do just that.

Problem: How do I fix my air conditioner not cooling?

Potential Causes/Solutions: Possible causes include refrigerant that is low or leaking, thermostat issues, a clogged drain or a dirty filter. You can (and regularly should) change your A/C filter. You can also check to make sure your condensate drain line is not clogged, and check your thermostat to make sure it’s set properly and is reading the correct temperature. Issues involving refrigerant are best handled by an HVAC professional.

Problem: My central A/C 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 air ducts could be clogged, 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 conditioning systems, our HVAC technicians can check for 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 an inefficiency. After a dirty filter, the most likely culprit may be a choked condenser coil. If so, it’s probably time for a tune-up from an HVAC professional.

Frequently Asked Questions

Q: What’s the most important thing I can do to help keep my A/C system running smoothly?
A: Most importantly, you should change your filter regularly. This helps your cooling system operate at peak levels while improving indoor air quality. The U.S. Department of Energy reports that changing your HVAC filter can lower your air conditioner’s energy consumption by 5% to 15%. High-quality 4-inch-thick filters should be changed every 6-9 months, while cheaper 1-inch filters may need to be replaced every 30 days.

Q: What certifications does an HVAC technician need?
A: HVAC technicians handling controlled refrigerant are required to have Environmental Protection Agency Section 608 certification. State licensing requirements vary greatly, so homeowners can gain added peace of mind by choosing a contractor whose technicians receive advanced training and certification from NATE (North American Technician Excellence) — the nation’s largest nonprofit certification organization for heating, ventilation, air conditioning and refrigeration professionals.

Q: How will I know when to call for an A/C repair?
A: Signs that you may need AC service include: leaking around the outside unit, air coming into the house that isn’t cool enough, short-cycling or constantly turning on and off, higher-than-normal energy bills or excessive noise during start-up and operation.

Q: How long will my A/C system last?
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: 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 does an air conditioner work?
A: Heat is extracted from the home by passing indoor air across a refrigerant coil. Refrigerant lines carry the heat to the outdoor unit, where it is released into the outside air. A fan blows air across the chilled coils into your home. The cooling cycle continues until the indoor temperature reaches the thermostat setting. The process is explained in this Energy Saver 101 infographic from the U.S. Department of Energy.
