Where to start

Most cooling calls fall into one of three situations.

Why cooling systems fail in July

Air conditioning fails the same way heating does: under load, at the worst moment. A system that ran acceptably through a mild June will give out during the first stretch of genuine heat, when it goes from cycling occasionally to running for days.

That is why cooling failures cluster — an entire region's marginal systems give out in the same week, which is also the week every HVAC company is booked solid. The failure was developing long before; the heat only exposed it.

The counter to that is the same as on the heating side. An inspection in spring finds the weak capacitor, the restricted coil and the low refrigerant charge while they are still scheduling questions rather than emergencies. If your system is working now but has not been looked at in over a year, seasonal AC maintenance is the more useful call.

What to expect when you call

  1. You describe what is happening

    Whether the outdoor unit runs, whether air is moving, how warm it is getting, when it started. These details genuinely narrow the diagnosis.

  2. We diagnose before quoting

    We identify the actual fault rather than estimating from a description. Refrigerant systems in particular are not something to guess at.

  3. We explain what we found

    The problem, what fixing it involves, and what it means for the system overall — including whether it is worth fixing.

  4. You decide

    Nothing proceeds without your approval, and where repair and replacement are both reasonable we lay out both.

Cooling equipment we work on

Central air conditioning — the ducted split systems most common in our area, with an outdoor condenser and an indoor coil paired to your air handler or furnace. Repair, maintenance and replacement.

Heat pumps — systems that cool in summer and heat in winter from the same equipment. Increasingly common, and worth understanding if you are replacing a cooling system anyway.

Ductless mini-splits — for additions, converted spaces, rooms that never cool properly, and homes without ductwork. Often the right answer for a single problem area rather than replacing a whole system.

If comfort problems persist after the equipment is working correctly, the issue may be air distribution or the building itself — see indoor air quality and energy efficiency.

Air conditioning questions homeowners ask

Why is my air conditioner running but not cooling?

This is one of the most common calls we get, and it has several possible causes: restricted airflow from a dirty filter or blocked coil, a refrigerant problem, a failing compressor or capacitor, or a system that has iced up. The distinction that matters is whether the outdoor unit is running at all. If the indoor blower runs but the outdoor unit is silent, that narrows things considerably. Mention which it is when you contact us.

Should I cover my outdoor AC unit in winter?

Generally no, and a full wrap can cause problems. Outdoor units are built for outdoor conditions, and sealing one up traps moisture and gives rodents an attractive sheltered space to nest in wiring. If you want to do something useful, keep the top clear of leaves and debris and make sure nothing is piled against the sides restricting airflow. If you have a heat pump, do not cover it at all — it runs year-round.

How long does a central air conditioning system last?

It varies with equipment quality, installation, and how consistently the system has been maintained. Maintenance is the variable homeowners control, and it shows: systems that get annual attention tend to reach the upper end of their range. Rather than quote a figure that may not apply to your equipment, we would rather look at what you have and tell you where it actually stands and what to plan for.

Why is one floor always warmer than the other?

Heat rises, so upper floors are harder to cool — that part is physics rather than a fault. But a pronounced difference usually involves something fixable: duct design or leakage, insufficient return air upstairs, a system sized for the square footage but not the layout, or insulation issues. Sometimes the answer is a ductless mini-split for the problem area rather than replacing a system that serves the rest of the house well.

Is it normal for my AC to run constantly on very hot days?

Longer run times during extreme heat are expected — systems are sized for design conditions, not for the hottest few days of the year, and a correctly sized system will run nearly continuously during a heat wave. What is not normal is running constantly while the house gets steadily warmer, or running constantly in ordinary summer weather. Those suggest lost capacity, airflow restriction or a system that was undersized.
