To ensure your home, family, or business, is not without safe, efficient, and relieving air conditioning, we examine a range of factors to determine the necessary repairs for your current air conditioning system.

What’s Wrong With Your AC?

The calls we get about problems with AC units tend to be similar:

  • AC won’t turn on.
  • AC turns on but doesn’t blow any air.
  • AC blows only warm air.
  • AC is making a loud noise.
  • AC is leaking.
  • AC unit is covered in ice.

Some of these problems are easier to fix than others, but all require a visit from an HVAC technician and a diagnosis. Once we determine what the problem is, we give you an estimate on how much it will cost to fix, along with our recommendations.

If your unit is old, your money might be better spent replacing it with a new, more efficient model. But our recommendations are just that: recommendations. The final decision about whether to repair, replace or do neither rests with the customer.

Deciding on Air Conditioning Repairs

To determine whether or not you should pursue air conditioning repairs, you may consider the following questions:

  1. How old is your current system?
  2. How frequently has it been repaired?
  3. Does it require additional refrigerant? (If so, this is a symptom of a coolant leak.)
  4. Is your energy bill increasing?

The older your system, the more frequent the repairs. As your air conditioning system ages, the complications of damage, rust, or possible leaks, dramatically increase. Furthermore, as technology is fast advancing, your older system might be more outdated than you think, running loudly, inefficiently, and, sometimes, unsafely. Older systems, usually, have been repaired frequently. When working with an older system, you may want to consider a complete air conditioning replacement. Take a moment and read our air conditioning installation page to see if our new air conditioning installation services better fulfill your needs.

If your air conditioning system requires additional refrigerant, there is a strong chance your system is experiencing a coolant leak. Coolant leaks can be dangerous, and cause your system to run inefficiently, raising the cost of your energy bill. A high energy bill alone can be symptomatic of needed repairs. Other signs your air conditioning needs immediate repairs are sluggish air circulation, weak air circulation, or completely stalled air circulation.

AC Maintenance = Fewer Repairs

The main cause for most AC breakdowns is a lack of proper maintenance. Some AC maintenance you can do yourself as a homeowner or a business owner, but other tasks you should leave in the hands of a trained professional. Talk to our team about what you can do to help keep your AC running smoothly, and read more about our recommendations for AC maintenance.

Regular maintenance not only helps in avoiding unexpected breakdowns but also extends the lifespan of your air conditioning system. By ensuring filters are clean, coils are cleared of debris, and electrical connections are tight, you can maximize energy efficiency and reduce operational costs. Scheduled check-ups can also identify potential issues early, saving you from costly repairs down the line. Notably, these practices are particularly important in Gaithersburg, where humidity and fluctuating temperatures can strain AC systems throughout the year.
